Railsimroutes returns – work resuming on projects, new website design, content updates including updated openBVE help guide and computing section, new UKTrainSys bugfix releasePosted by Anthony Bowden on 10th April 2019 at 11:58 pm
Railsimroutes returns – new site design, work resuming on projects
Well it’s been an incredibly long time since the last update here at Railsimroutes… In the intervening years I’ve been very busy, and many things have changed with real life taking precedence. I studied for a Foundatation Degree in Railway Engineering and embarked on a career with the real railway, which as you can imagine didn’t leave much spare time to devote to the simulated world of openBVE.
However I now feel able to return to the hobby and I would really like to get my projects released. I intend to finish off some of the tasks I started working on back in 2014, make the add-ons usable, and aim to get at least something released. These releases won’t be as polished as previous versions, but given that all material will be released as open source and placed into the public domain, it can always be improved upon further down the line (pun intended!).
Given how openBVE has developed lately, I also want to release the UK Railway Infrastructure Object Library soon to give the project a boost and provide a nice graphical upgrade for developers or users who wish to use its objects and textures.
UkTrainSys plugin update – bugfix release v0.3.2.0
Thanks to Chris Lees, I was notified (a long time ago!) of a bug in the Train Protection and Warning System (TPWS) simulation where an incorrect variable in the
ArmTss() method was reset upon passing an opposite-direction TSS f5 frequency. This was caused by a typo which Chris spotted in my code! Please head over to the UkTrainSys Plugin page for the updated version. I have also updated the Class 323 3D Cab Add-on with the updated UKTrainSys.
New website design and content updates
I wanted to learn HTML5 and revamp the design of Railsimroutes with a more modern format, using the latest web standards with a focus on current standards compliant browsers. So today sees the launch of the fifth incarnation of Railsimroutes, with a theme known as “Glass”. I hope you like the new design. It is aimed primarily at desktop PC and tablet users, but does employ responsive design for use on smartphones, which may be further enhanced in future.
- The new site design has been hand coded from the ground up to be fully HTML5 and CSS Level 3 compliant, and now fills a greater width of the browser window. Both a Light and a Dark theme variation are provided to suit your taste, with the Dark theme being the default.
- I have updated the openBVE Help and Installation Guides to reflect Chris Lees’ ongoing developments with openBVE. The new guide gives step-by-step instructions for installing openBVE 1.4.5.x in Windows 10 “Creator’s Update”, and now also includes a guide for macOS Mojave users (I am now a Mac user as well as die-hard PC enthusiast!).
- The About the Site and History section has been updated, and the previous “Clarity” theme can be seen in the Railsimoutes.net Archive.
- The Links page has been updated although this is still a work in progress. There are also many more non-railsim related links included near the bottom of the page.
- The PC Specs section of the site has now been significantly expanded, and renamed Development PC(s) and Network with a new URL. This section covers my long standing interest in computing, from my earliest PCs to my present day machines, including my office/development studio and networking setup, software choices, and so-on.
- Railsimroutes now has an SSL certificate installed, so the site can also be accessed via https://railsimroutes.net.
- I have also set up a mirror of the Railsimroutes website, which is also SSL enabled, at https://railsimroutes.com. This is hosted on my own server; feel free to use whichever you find more responsive.
More updates shall follow soon! I am working on the AWS/TPWS implementation in Watford Junction to Rugby next, and also the UK Railway Infrastructure Object Library. I’m working on these projects as and when I get the odd hour spare between my day job and other real-life stuff which has to come first, but I shall try and do more regular updates even if they’re not all that exciting!

openBVE v1.2.8 and increased rendering speed, openBVE v1.2.9 development branch with cross-platform .NET plugin support, Cross-City South v2.0 update, and openBVE performance with budget versus high-end CPUs, and discrete versus on-board graphicsPosted by Anthony Bowden on 14th October 2010 at 12:20 am
openBVE v1.2.8 released, with significant rendering speed improvements
openBVE v1.2.8 was released recently, which includes a reorganised renderer which can provide significantly higher framerates than the old renderer found in v18.104.22.168. This is achieved by rendering opaque faces (i.e. faces without alpha), using OpenGL display lists. There are two ways to enjoy the performance increase; if you currently have low framerates, then the boost could make routes more enjoyable, however if you already have high framerates, then you can increase the viewing distance significantly so that you can see much further away from the train, whilst maintaining similar framerates to those you are already used to seeing. You can visit the Official openBVE Homepage for the download and to read the changelog, as well as read this thread on the openBVE forum for more information.
Here are some framerate and image quality comparisons which I conducted on my main development PC (Core 2 Quad Q9650 / GeForce GTX 260), showing some notable improvements:
|On the left is openBVE v22.214.171.124, and on the right, the new v1.2.8:|
openBVE’s default viewing distance is 600 metres, however, here are some screenshots showing what the upcoming Watford Junction to Rugby route looks like with an increased viewing distance of 2000m. This particularly benefits the straight sections of this route, allowing you to see more than one upcoming signal at the same time. Thanks to the new renderer, it’ s possible to significantly increase the viewing distance, while still having very playable framerates on a good computer with reasonably detailed exterior car objects:
Most people are reporting better performance with the new renderer, however if you notice any previously unseen stuttering with the new renderer and detailed routes, I’d really appreciate it if you could contact me with some information about your computer’s specifications and the route being used, as it might be useful for me to know, when I draw up recommended system requirements and openBVE settings, particularly for the upcoming Watford Junction to Rugby project. Thanks.
openBVE v1.2.9 development branch released, enabling support for cross-platform .NET train plugins
The latest version 1.2.9 development branch of openBVE, includes support for .NET assemblies (plugins), which enables cross-platform plugin compatibility, just as with openBVE itself. With previous versions of openBVE, and of course BVE Trainsim, only Win32 C++ plugins were supported, which limited their use to the Microsoft Windows platform, leaving Linux and Mac users to rely on openBVE’s built-in safety systems only, with a great deal of functionality found in plugin enabled trains unavailable. With .NET assemblies, these can be written in a variety of languages which target the .NET framework, such as C# or Visual Basic .NET, and users of non-Windows operating systems can also enjoy enhanced train functionality once new .NET plugins start to appear.
Anyone with at least some programming experience can visit the .NET assembly train plugin section on the official openBVE website, to download template projects to help you get started. If you’ve already developed a Win32 C++ plugin previously, you might prefer to look at the “C# project files (for updating from Win32 plugins)” download specifically. Anyone interested in making general comments can do so in this thread on the openBVE forum, while anyone wanting to help improve the design of the plugin API by making suggestions, can visit this thread instead.
I’ve started writing a replacement .NET plugin for the class 323, although I’ll design it such that it could be used with other trains too. I’ll release the new .NET assembly and publish the source code when there’s something worth showing, unless someone else writes a plugin which is sufficiently good enough, before me.
Birmingham Cross-City South v2.0 update
If you’ve been keeping an eye on the news infobox at the top left of the blog (or my Projects page), you’ll have noticed that I’ve been continuing work on the pointwork along the Cross-City South route, and I’ve also been working on updating the pointwork on the approach to Birmingham New Street as well. All pointwork between Alvechurch and Five Ways is now finished, and ready for animation to be applied prior to release. The pointwork on the approach to Birmingham New Street is a rather difficult task though. At this location, there are single and double slips, switched diamond crossings and three-way points, all crammed into a rather small space, and all located on quite a sharp curve. There are also a variety of point machines, including electric, hydraulic clamp-lock, and Westinghouse electro-pneumatic types, as well as cast manganese steel and conventional frogs. I like to model these kinds of details, so I’ve spent quite some time working on this area – I’m not finished yet, but will be shortly. Cross-City South was originally designed with a 25 metre block length in mind, however the pointwork doesn’t fit neatly, so much of the pointwork is contained in two large set-piece objects instead. I always felt that this task was going to be the hardest part of the Cross-City South v2.0 upgrade, as it’s rather tedious and difficult (and indeed I was right), however for me, the route wouldn’t be complete without it, as I want Cross-City South v2.0 to be of the same standard as Watford Junction to Rugby, so I’ll endure the pain.
Here’s a screenshot of one of the Birmingham New Street pointwork objects:
At first glance it doesn’t look like much, but on closer inspection, it’s actually rather detailed and intricate. This object features 4076 vertices, and loads 9 textures. Each rail is carefully texture mapped, to ensure that the Pandrol rail fasteners are as closely lined up with the underlying sleepers as possible, and that the inside of the railhead as depicted in the texture, matches the mapping on the object. Depending upon the location of a rail within the point assembly, different kinds of rail fasteners are depicted. If you examine the existing equivalent object in Cross-City South v1.31, you’ll notice that that old object is afflicted with z-fighting issues; I’ve taken special care to ensure that this doesn’t happen with the new version. In the case of the cast manganese steel frogs, these feature a combination of 3D geometry and use of a photographic texture of the prototype, to create the desired 3D effect:
Each fishplate is also modelled in 3D, and these are also responsible for much of the vertex count, incidentally – this also means that they can be easily removed to create a lower detail object, however. Each point blade has a texture depicting baseplates beneath it, and where the tie bar assemblies will go, oil-stained ballast is featured. The object has also been designed in such a way, that animating any of the point blades is very easy to do in future. I’ll post a screenshot of the object within the route, once I’ve finished the second of these pointwork objects, improved the appearance of New Street station a bit, and finished some other things.
Prior to starting on the New Street pointwork updates, I also spent some time working on the Kings Norton area. In the existing Cross-City South v1.31, I didn’t lay any track in the sidings to the west of the station, and instead, I included a simple texture depicting a pair of tracks on a flat surface to the right of the loop siding. Cross-City South v1.31 was designed for BVE Trainsim 2 and 4 with their cab-only view and lower resolution, of course, so there wasn’t much point in modelling the extra tracks. With openBVE, it’s well worth adding them, however:
Here are some screenshots of the updated pointwork and track geometry at Kings Norton (I’ll replace these points with the more recently installed concrete sleeper versions soon):
You might have noticed that scenery has been improved a little in those previous three screenshots; I’m currrently adding the embankment/tree alpha shadow technique I developed for Watford Junction to Rugby, throughout the Cross-City South route as well. Here are a few more screenshots showing the latest scenery enhancements I’ve been working on, as well as little things like extended length sleepers beneath electric point machines, and disused trackbeds:
Sometimes I see people talking about poor framerates or image quality in 3D games which they use, such as openBVE, or others. Upon finding out about the system specifications in use, the cause of the low performance, in the case of Windows 7 and Vista, is often due to inferior graphics drivers being used (i.e. those bundled with Windows by default or obtained via Windows Update, rather than from the graphics card manufacturer). However, the other frequent cause of unsatisfactory performance, is a slow graphics card, and sometimes, a slow CPU.
Personally, I’ve used less-than-stellar graphics cards in my desktop PCs for use with openBVE, but being a geek, I’ve never used on-board graphics solutions (integrated on the motherboard) in a desktop PC before, as I’ve always dismissed them as not being up to much. It occurred to me that perhaps I was being too hasty in writing integrated graphics off, as I’ve never actually tried to play games on such a solution in a desktop PC myself. The same goes for budget CPUs, such as those in Intel’s Celeron or AMD’s Sempron lines – I’ve never been interested in them as I’ve always viewed them as merely cut-down versions of “real” fully-featured CPUs, such as those in Intel’s Pentium and Core product lines, or AMD’s Athlon and Phenom lines.
So, I thought I’d test openBVE on a contemporary budget PC to find out what it was capable of, with the cheapest of Intel’s newer CPUs that I could find – a socket LGA 775 based Celeron E3300 with the Wolfdale-3M core (the same core used in Core 2 E7xxx and Pentium Dual Core E5/6xxx processors), which runs at 2.5 GHz with 1MB of Level 2 cache. This CPU is combined with the cheapest of all graphics solutions – on-board graphics integrated onto the motherboard – in the form of Intel’s “Graphics Media Accelerator” X4500, which is a part of the G41 Express “Eaglelake” chipset. I was also curious to find something out – if a choice has to be made between a better CPU or a better graphics card, which is the best to go for where openBVE is concerned?
I ran the hardware in a few configurations, and tested openBVE’s performance with my upcoming Watford Junction to Rugby route. Here are the results, and in all cases, the best image quality that each graphics solution is capable of was selected, and in all except the last test (number 4), the following constants apply:
CPU: Intel Celeron E3300 @ 2.5 GHz
RAM: 2 GB PC-6400 DDR2 SDRAM (dual-channel configuration)
Operating System: Windows XP Home Edition (32-bit)
openBVE version: 1.2.8 (Sharp transparency, 1920×1200 fullscreen, 600m viewing distance)
Test setup 1:
Graphics: Intel GMA X4500 (G41 Express Chipset, 128MB shared video memory) [Antialisasing: n/a, Anisotropic Filtering: 2x]
|Bourne End Junction||9|
Test setup 2:
Graphics: AMD/ATI Radeon HD 2600 Pro (256MB DDR2) [Antialisasing: 8x, Anisotropic Filtering: 16x]
|Bourne End Junction||24|
Test setup 3:
Graphics: NVIDIA GeForce GTX 260 (896 MB GDDR3) [Antialisasing: 16xQ, Anisotropic Filtering: 16x]
|Bourne End Junction||101|
Test setup 4:
Lastly for comparison purposes, here’s what we get when the GeForce GTX 260 is paired with a faster and more powerful quad-core CPU:
CPU: Intel Core 2 Quad Q9650 @ 3 GHz
Graphics: NVIDIA GeForce GTX 260 (896 MB GDDR3) [Antialisasing: 16xQ, Anisotropic Filtering: 16x]
RAM: 4 GB PC-6400 DDR2 SDRAM (dual-channel configuration)
|Bourne End Junction||160|
From these results, we can see that the budget Celeron E3300 is actually a rather nice CPU (which isn’t too surprising I suppose, given the architecture in use), and more than good enough for highly detailed routes such as Watford Junction to Rugby when paired with a decent graphics card. By comparing the two GeForce GTX 260 results, we can see that the speed of the CPU matters, however performance is also very clearly determined by the graphics hardware, and I would say that it’s the more important factor when it comes to openBVE performance. While I didn’t test the Core 2 Quad CPU with Intel’s GMA X4500 integrated graphics, I think it’s highly unlikely that framerates would have been much higher with this combination (overclocking the Celeron E3300 from 2.5GHz to 2.92GHz, made a difference of only around 1 fps when the integrated GMA X4500 was used). Intel’s on-board graphics is simply too slow, and the image quality is a bit poorer too, as there is no antialiasing, and the anistropic filtering level is rather limited (compare this screenshot using Intel’s GMA X4500, and a screenshot using the GeForce GTX 260). Intel’s driver control panel claims to support 16x anisotropic filtering, although openBVE/OpenGL reports that 2x is the maximum supported. The framerates don’t tell the entire story either though, as the much faster GeForce GTX 260 graphics card also gives more fluid and stutter-free performance than the budget Radeon HD 2600 Pro does. This is especially true when large textures, animated objects and higher levels of antialiasing and anisotropic filtering are used, as well.
So, if anyone is thinking of upgrading their computer soon and would like to run something like Watford Junction to Rugby, and money is tight, then my advice would be to bias your budget in favour of getting the best graphics card possible, while trying to keep some balance between the CPU and GPU in terms of what each is capable of. For the energy conscious amongst you, also bear in mind that newer generation graphics hardware tends to be more power efficient for a given level of performance. While quad core CPUs are nice to have, dual core CPUs are just fine, too. Indeed, running openBVE on only two of the four cores of the C2Q Q9650 CPU, by setting the affinity for the OpenBve.exe process accordingly, makes only a small difference to performance. Running openBVE on only a single core, even at 3 GHz, does result in performance being halved though, therefore I can’t recommend a single core CPU any more, when dual core CPUs are so common now. Of course, if you can live without the rich graphics or geometrical complexity of the latest openBVE routes, and only want to run less demanding examples, or those previously designed for BVE Trainsim, then even the cheapest contemporary hardware including on-board graphics, may suit your needs just fine where openBVE is concerned, if you don’t mind losing a little image quality and have realistic expectations.
For example: [ Uchibo – Intel GMA X4500 | X-City South v1.31 – Intel GMA X4500 | Saijou Line – Intel GMA X4500 ]

Transition curves and superelevated track created using the Object Bender tool, and Cross-City South v2.0 progress updatePosted by Anthony Bowden on 5th September 2010 at 7:30 am
I’ve been doing some more work on Cross-City South v2.0 during the past couple of weeks or so, and I’ve been making good use of odakyufan’s new Object Bender tool, where incidentally, the code was so well written and the functionality comprehensive enough, that Object Bender has been made into an official openBVE tool. Please see the new Object Bender section on the official openBVE homepage for more information: Developing for openBVE: Object Bender.
The output from the tool is such, that I’ve decided to replace all the curved track objects used in the Cross-City South route with new objects generated by Object Bender (from a set of “template” objects which form the intial segment in each type of track – please see here for an example of what I mean), and later I’ll do the same with Watford Junction to Rugby, too. I had already manually created a full range of suitable UK style track objects incorporating cant, as well as objects to be used in transition curves, however these objects had one rail lowered and the other raised in height, to suit the cant model used in older versions of openBVE (therefore enabling the wheels to be visibly touching the rails at all times in earlier versions). openBVE v126.96.36.199 features an improved superelevation model however, where one rail is raised above the other (which remains at the same level), so the existing objects were no longer so suitable.
I had started to make some progress in manually modifying my existing objects, however Object Bender has now saved me many days of work, possibly weeks, thereby preserving my sanity and enabling me to easily generate a much more comprehensive range of superelevated track and transition curve objects to create some very nice results, even better than what I’ve shown in Watford Junction to Rugby for a long time now. The slight downside is that the generated objects have a larger filesize compared to the objects I’d entirely hand-written, however Object Bender’s command line arguments also let me automate and recreate many hundreds of track objects, from a handful of source objects, with great ease via shell scripts. This benefit is simply too good to pass up – if I decide that I want to improve or alter my depiction of track in future, all I have to do is edit the handful of template objects and I can recreate the entire library of track objects with just a double-click. An example batch file for Windows users, based on the one which I’ve written for myself, can be found below, along with a sample shell script for Linux users too.
Here’s a selection of screenshots to demonstrate what nice results can be gained quickly, thanks to Object Bender and a little object building skill:
Birmingham Cross-City South v2.0 with superelevated track and transition curves, created via
odakyufan’s Object Bender tool. Also note the embankment (dike) with curved cable trough
in the last screenshot, with the vegetation handled via Object Bender’s /a command-line
argument (please see the Object Bender documention for a tutorial).
One problem I have encountered during the latest Cross-City South superlevated track upgrade so far, is how to accomodate pointwork (switches) on superelevated curves. There are examples of this at Longbridge, between Northfield and Kings Norton, and just after Kings Norton, too. On Watford Junction to Rugby, I took the easy option and handled such situations by transitioning back to uncanted track on either side of points (only with the visual representation of the track – the cant applied via the .Curve command remained constant throughout the points). With Cross-City South v2.0, I’ve decided to gradually alter the height of the other tracks leading towards and away from crossovers connecting superelevated tracks instead, while also rotating the point objects around the Z-axis. This way, the crossover itself is superelevated to the same degree as the tracks being crossed between, which looks better visually, and I presume it’s also more prototypically accurate. Here’s an example between Northfield and Kings Norton, with some new custom pointwork objects I’ve been working on for this location (amongst others):
Birmingham Cross-City South v2.0 with superelevated track and custom-built crossovers.
Note the clamp-lock point machines, too.
Object Bender has most definitely made route building easier and more enjoyable for me, however one problem which needed to be solved, was that when a track object is superelevated, the terminating height of the ballast shoulders on either side of the sleepers is also altered. In a route, and depending upon the design of the track objects, this can lead to gaps appearing between tracks running side-by-side, and between the ballast portion of the track objects and dikes (i.e. the embankment beneath the track):
Depending on the design of track objects, gaps can appear
between the ballast shoulder and dike, or a parallel track,
when superelevation is applied via Object Bender.
I’ve solved this problem, by expanding the ballast shoulder in the track object to include two faces at increasing angles, such that at the maximum level of visible cant I’ll ever apply in my routes (160mm in my case), no gaps appear and the cable trough isn’t obscured, while I can continue to use only one template object for creating the full range of curved track pieces, at differing degrees of superelevation, via Object Bender. The ballast portions of the dike objects are also extended. This solution does lead to more faces being rendered, but hopefully it’s not too much of an issue, performance wise. Here’s a screenshot:
Extended ballast shoulders in both the track and dike objects,
to remove visible gaps when cant is applied via Object Bender.
Object Bender supports some markup which can be applied to template objects before they’re processed, for example, to determine the desired texture coordinate shifting in generated segments (please see the Object Bender documention on the openBVE homepage for more information – I think the tutorial is clear enough that I don’t need to explain it further). I was originally going to suggest expanding the supported markup a little, so that Object Bender could be instructed to leave the X and/or Y coordinates of any vertex as it is in the original template object, which would for example, solve the ballast shoulder issue above in an easier way for the object creator. However, I quite like the appearance of the solution I came up with, so I don’t think such a change to Object Bender is too important, but might be nice to have, nevertheless.
Lastly, for more advanced users, or beginners feeling more adventurous, here’s a sample batch file for Windows users, and a bash script for Linux users, which you can adapt and expand if you want to automatically create a range of curved objects using Object Bender’s command line interface, rather than the GUI. There is a simple example of a suitable batch file included in the Object Bender documention, however rather more can be done with batch files/shell scripts. These following example scripts use variables to reduce the amount of duplicated text that you might otherwise need to type, and they also create a logfile which you can read, which is handy if you’re generating a large number of objects, to more easily check for any errors which might have occured during a lengthy object bending batch process.
For the Windows batch file, you need to give it a .bat extension. The text highlighted in red (including the less/greater than characters), should be replaced by any paths or filenames which are appropriate for your purposes. Where <Your_File_To_Append> is concerned, this object file could contain fishplates for example, or overhead wires, which are appended to the object generated in the previous line (please see here for more information). You can see fishplates added to my curved wooden sleeper based track objects in the above Cross-City South v2.0 screenshots – this is how they were appended to the files generated via Object Bender.

Linux users can adapt the following shell script to make use of Object Bender for automating the creation of multiple files. Your script should be given a .sh file extension, and be made executable (for example: chmod +x myscript.sh). The script can be executed from the Terminal prompt by typing, for example: ./myscript.sh). Don’t forget that Object Bender requires Mono to be installed, too.

openBVE v1.2.5, Watford Jn. to Rugby progress, class 390 Pendolino, other developer’s add-ons, Cross-City South bugfix, and one million visitsPosted by Anthony Bowden on 31st January 2010 at 5:50 pm
openBVE v188.8.131.52 released
openBVE v184.108.40.206 was released a few days ago, and various changes have been made to openBVE since my last blog entry. In this release, the main form (i.e. the window for route selection, setting options, etc.) is smaller so that it can be used on smaller screen sizes (e.g. 800×600) or with larger fonts, and if the window is resized, the new size is saved between sessions. The player’s train now derails when passing the end of the track, as well.
Michelle has also written an impressive RIFF/RIFX/WAV PCM/ADPCM parser, which she’s ported from openBVE’s successor to openBVE 1. This removes the need for two dependencies, namely ALUT and SDL, and her parser supports a wider range of sampling rates. Other improvements recently, include a shortening of loading times for routes using detailed animated objects (which eventual users of the projects being developed here will appreciate). Also, there’s the addition of the $Include preprocessing directive which allows text in other files to be parsed in place of the directive in a route file (with random selection of multiple included files), and point-based turns (via the .Turn command) are smoothened out, which gives much more pleasing results. Please see » this thread « for more discussion about these latter features.
Watford Junction to Rugby progress update
It’s been quite a while since I posted any updates regarding my routes, so I thought you might like to know what’s happening with the Watford Junction to Rugby project this time. I’m relatively happy with the state of the permanent way and between-station railway related lineside objects, so I’m now implementing some more scenery enhancements, including improved under-bridge shadow effects, moving road vehicles, and lineside buildings. I’ve also, at last, started working on the stations and so far I’ve created new photo-realistic lamposts, photo-realistic 3D platforms, and various signs.
Previously, the underbridge shadows I’d implemented were simple untextured meshes with alpha applied via the SetColor command. In addition, I’ve now applied a small 8×8 pixel texture where the outer 28 pixels act as the transparent color, and the inner pixels are nearly black. When this texture is applied to the existing shadow meshes and the color adjusted accordingly, smoothly transitioned shadows can be achieved. I’ve also added deeper shadows to the sleeper textures to improve the appearance of the track, and added more blue colouration along with reducing the lightness of the railhead, to make the rails look a little more metallic. I’m also implementing shadows cast by platforms and embankments as well. The way in which I’ve implemented the latter can give the appearance of dappled sunlight caused by trees, and increases the effect of warmth created by sunlight and the realism of locations within cuttings, although this feature will be optional in the final release as there’s a possibility that it may incur a performance penalty on slow graphics cards. Lastly, I’ve added some new photographic backdrops which I’m experimenting with at the moment. Take a look at the following screenshots to see how the route is coming along (please note that there may be some inaccuracies, as the route shows trackwork or infrastructure as it was in different eras simultaneously at the moment):
Class 390 Pendolino
Some of you may remember that the class 390 Pendolino was given an » openBVE exterior car update « some time ago, thanks to Cramaboule. I’m pleased to announce that I’m now working with Cramaboule to produce some detailed exterior models of a similar quality to the class 323 I’ve demonstrated previously, along with a full 3D cab, so there will be some more nice looking rolling stock to run on Watford Junction to Rugby. I’ll post some screenshots as the models are developed, but for now here are some photos of what we can look forward to:

Other more recent openBVE add-on releases
Since my last blog entry, some high quality openBVE add-ons have been released. Just in case anyone missed these releases, here are some screenshots and links to some excellent new add-ons with rather beautiful graphics:

Upcoming openBVE projects to keep an eye on…
There are a couple of new projects in the works which I’m personally very much looking forward to seeing, namely » Odakyufan’s « representation of the Odakyu Odawara Line running from Tokyo’s Shinjuku station, and the new Iida line currently being developed. The latter will of course be known to BVE users as one of Gaku’s classics (see my links page), but the new Iida line, train and exterior car objects being developed at » http://mus-iida.jpn.org « look beautiful and very realistic so far.
Some superb early screenshots of » Odakyufan’s « representation of the Odakyu Odawara line were also published a little while ago. The Odawara line starts from Tokyo’s busy Shinjuku station, and the line is well known for it’s Romancecar limited express services for tourists visiting Odawara and the surrounding resorts, but it’s also a busy commuter route and the Odakyu Electric Railway uses it’s own OM-ATS safety system, which will be simulated in a semi-realistic way due to the absence of detailed technical information. Odakyufan has a goal of modelling at least the first five stations, and this will be interesting to see, as this section of the line is surrounded by densely packed buildings. The screenshots showing the exit from Shinjuku station, Japanese 1500V DC catenary and Tokyo’s buildings all look very promising indeed, and easily recognisable, even at an early stage of development.

Cross-City South bugfix
|I’ve uploaded an update for Cross-City South v1.31, which fixes the following issues:|
- Incorrect pathname in route files using the class 323 passenger views.
- The ground repeater signal prior to Birmingham New Street station is now accurately modelled, such that the red aspect is nearest to the driver (i.e. the signal is as though it were upside down now, as in reality). Many thanks to Paul Sladen for pointing this out.
- In the night routes, “P” has been added as the ArrivalTime argument of the Five Ways .Sta commands (to indicate that trains are not meant to stop). Thanks again to Paul for bringing this omission to my attention.
- Also in the night routes, the repetition count for Background(0) has been added, which was missing previously, leading to a horizontally compressed background image.
Existing Cross-City South v1.31.03 users can simply download a small update to v1.31.05 here: xcs_1_31_05_update.7z [180 KiB]. If you’re using a version earlier than v1.31.03, you might be better off downloading the full route pack again, which also now includes the aforementioned update. The previously separate class 37 and 158 route files are now included in the main download as well. Please also note that BVE 4 doesn’t work on my current Windows 7 64-bit/NVIDIA GeForce GTX 260 setup, so this update has only been tested in openBVE, as it’s inconvenient having to dual boot or use another computer every time I want to check some minor thing in the old BVE 4. There aren’t any changes which should affect BVE 4 users, but if any issues arise, please let me know with as much detail about the problem as possible, and I’ll investigate.
I noticed that the site has had it’s one millionth visit today (as opposed to page view), insofar as it’s possible to measure such things — the actual number of users of my routes will likely number in the low thousands, of course. Thank you to everyone who has taken an interest in my work during the eight or so years since this site was launched!
25th April 2009
Ubuntu 9.04 “Jaunty Jackalope” (which is a Linux distribution for any dear readers who may not be particularly au fait with the wonderful world of operating systems…), has just been released. With this version, it’s possible to install a seperately packaged, unofficial version of openBVE maintained by Paul Sladen (currently at v220.127.116.11; the » official openBVE « release is at v18.104.22.168 at the time of writing) via the ‘Applications’ > ‘Add/Remove…’ menu item (I haven’t used Kubuntu in a while and I’ve forgotten what the equivalent in KDE is). A specially prepared, public domain version of the Cross-City South route (v1.31.03) is also installed automatically when openBVE is installed via this method, along with a reduced functionality (plugin DLLs don’t work on non-Windows operating systems), public domain version of the class 323 which Steve over at » trainsimcentral « also kindly donated.
X-City South v1.31.03 is just a cut-down version of the public release available from this site, with the copyright files removed and alternative backdrops added, and fewer route files; I prepared it so that openBVE could be considered for inclusion in Ubuntu’s list of installable open source applications, as for a game engine to be accepted, it requires some equally permissively licenced game data to be supplied with it. Eventually the Ubuntu X-City South package should be identical to the official X-City South v1.4 package once it’s been released, and I hope to send any updates to Paul so the Ubuntu version is kept up-to-date; by implication, X-City South v1.4 will be entirely copyright free as well. Any copyright material, like the Birmingham New Street announcement audio files, will be available as an optional extra only.
After installing the latest ATi Catalyst drivers (and, at last, my Radeon HD 2600 Pro graphics card finally works with Ubuntu), it was nice to see openBVE running in Linux myself, and with decent framerates too. The framerate in the first screenshot of XCS v1.31 was 80 fps (90 fps in Win XP), and in the third screenshot, showing XCS v1.4, 17 fps (20 fps in Win XP). The latter screenshot actually includes more animated trees than will feature in the final XCS v1.4 release though, and in-cab, I was seeing up to 30 fps):
I admit there was also some momentary fascination after I turned on Ubuntu’s “Extra” visual effects option which enables hardware accelerated graphical effects to be applied to windows, and watched my X-City South v1.4 development route carry on running at 25-30 fps while I distorted and bounced the poor helpless openBVE window around the desktop (sorry I wasn’t able to capture a screenshot, just a low quality video still):
I may be finding that framerates are just a bit lower than in Windows XP, but they’re still good and I enjoy using openBVE in Ubuntu instead. The application’s forms all rendered nicely although the loading and error dialogs remained visible once the SDL window was created; I’ll carry on testing it and see if I notice any other issues.
Any Windows users who might be considering trying openBVE on Ubuntu, should remember that plugin DLLs don’t work natively on non-windows operating systems, so various functions in BVE 4 trains like TPWS won’t work. For this functionality to be available in Linux, you’ll need to use openBVE with Wine instead, which isn’t quite as easy to set up (I haven’t personally had time to try it yet, but as shown in this » YouTube video of the Northern Line « for example, if you do go to the trouble, it’s well worth it).
Edit (1st May ’09): I have tried and succeeded in getting openBVE v22.214.171.124 running with Wine and Mono 2.4 for Windows in Ubuntu since this entry was published, and it was quite easy after all. See the comments for more. 🙂
