• At DPSimulation we host a wide range of Train Simulator freeware including Train Simulator add ons, Train Simulator free routes, Train Simulator free scenarios, Train Simulator free reskins and Train Simulator free content.
• Open Rails: free train simulator that supports the world's largest range of digital content. Download the installer 08 December 2018, 44MB) Key Changes in v1.3. Timetables can join and split trains to form new trains. Or you can try out the 2 self-installing models on our home page - both free of charge.
• Electrification of the Cross-City Line with the UK's MkIII 25kV AC overhead system began in 1991, and the route was energised in 1993. Initially, electric services were operated by ageing class 304, 308 and 310 EMUs, as the then new class 323s weren't ready en-mass until 1994-1995.

So what is SimSig?

Welcome to the world of railway signalling! SimSig brings the signal box to your home PC and with it the enjoyment and frustrations of running today's (and some of yesterday's) railways. How often has your train been delayed because of 'signal failure' and you've wondered why trains can't be routed around the problem - or why it is even a problem in the first place? You'll soon see exactly why - with SimSig!

Welcome to British Trainz. This is a fan site for the Trainz railway simulator series. Here you will find freeware releases made by myself (Marky7890) for trainz. The scenery items are mainly based on real buildings around Cornwall and West Devon (for routes I'm currently building).

SimSig puts you in the seat of a signaller, also called a Dispatcher or Network Control Officer, operating signalling screens based on the widely used IECC and Westcad graphics used in the UK. That is, you operate the signals and points/switches in order to get trains to their destinations on time. SimSig has a wide range of areas you can operate including large portions of the UK, a small US simulation, and a couple of Australian areas. Each has its own challenges and skill level, the latter ranging from easy to mentally complicated.

The Brief Specs

• Replicates the operation of British IECCs (Integrated Electronic Control Centres)
• All signalling equipment simulated (track circuits, points, signals, etc.)
• Correct signalling (overlaps, aspect sequencing, approach control)
• Emphasis is on quality and realism, not quantity
• Used by signallers, drivers, and other professionals from all over the world
• User oriented - tell us what you want, we'll try to produce it!
• Free demo downloads of every simulation available right now

SimSig runs on Windows 7, 8.0, 8.1, and 10.

SimSig also runs on emulators such as Wine for Linux and Crossover for Mac. This is not guaranteed but we try to keep such emulators supported. Tablets and phones are not supported.

How much is it?

You can peruse prices in our Shop but we have several free simulations, then range from under £10 upwards, depending on the complexity of the simulation. All simulations come with an evaluation period so you can try before you buy.

Can I play with friends?

Yes! Many of our simulations are suitable for multiplayer. The larger simulations have as many as nine positions keeping people busy. But many simulations also have optional automation such as ARS (Automatic Route Setting) which means you can run a larger simulation by yourself.

Multiplayer works over the Internet, or your home LAN. One person acts as the host while others connect with an IP address and port number. We have run multiplayers across the world with members in the UK, the US, Australia, Europe, and elsewhere.

Many simulations can be 'chained', which is where adjacent areas can be linked together to form a larger area.

Can I contribute?

Unlike other products, anybody can write a timetable using the in-built timetable editor. We also do not charge for extra timetables. Our files area has plenty of user-contributed timetables to download.

Sorry, users cannot produce simulations themselves.

What does it look like?

Here we have the free Liverpool Street simulation running. ARS (automatic route setting) is setting the routes but we can easily take over. The eighteen platforms at Liverpool Street in London are very busy during the morning rush hour that we see here. The blue four-character labels are the train descriptions (like a flight number) such as 2H07. The signaller can identify the routing and destination of the train from that train description. The flashing white blobs indicate that a train is ready to depart. White lines show route set for trains, while you can see the signals showing red (stop), yellow (caution), double yellow (preliminary caution), or green.

This animated GIF is running at approximately 4x normal speed.

You must download and install the system files (from the Download Now! link above; under 3MB) before any simulations can be played

Installation Questions from the FAQ

Which platforms does Open Rails run on?

Open Rails works well on Windows PCs from Windows XP* onwards (including Windows 10). It does not work on Windows XBox, Windows Phone or non-Windows platforms.

* Windows XP requires Service Pack 3 (SP3).

32-bit or 64-bit Windows?

Open Rails is currently a 32-bit program that will run on either 32-bit Windows or 64-bit Windows. When run on a 64-bit Windows system there are some benefits as follows.

Programs compiled for 32-bit Windows are always limited to using a maximum of 2GB of memory. Many current PCs, especially 64-bit systems, have more than this. Fortunately it is possible to compile a program, for 64-bit systems only, which can use up to 4GB of memory and this is called a Large Address Aware (LAA) option. The downloads include both the usual version and the LAA version and you choose between them in the Options form.

What hardware does Open Rails require?

• Processor : 2.0 GHz (32 or 64-bit)
• Memory : minimum = 0.5 GB, recommended = 2 GB
• Hard drive : 40 MB (but models require lots of space. The 6 routes in Microsoft Train Simulator require 1.4 GB)
• Graphics Hardware : minimum = 128 MB dedicated video RAM with Pixel Shader 2.0, recommended = 256 MB RAM with Pixel Shader 3.0
• Graphics Software : as provided by Windows. Open Rails currently uses DirectX^® - version 9.0c
• Sound : compatible with DirectX^® - version 9.0c

Do I need Microsoft Train Simulator installed to use Open Rails?

You do not need Microsoft Train Simulator installed in order to use Open Rails.

When Microsoft Train Simulator is installed, then Open Rails can safely make use of all the Microsoft Train Simulator content as it does not change any Microsoft Train Simulator files.

Most non-Microsoft Train Simulator routes, activities and rolling stock make use of some Microsoft Train Simulator content, usually sound files, textures and cab interiors. If products designed for Microsoft Train Simulator are used on a PC with Open Rails but not Microsoft Train Simulator, then they are likely to work but some sounds and textures will be missing. Such files will be listed with warnings in the Open Rails log file.

How can I recognise add-on products for Microsoft Train Simulator that require Microsoft Train Simulator files?

Add-ons designed for Microsoft Train Simulator may rely on files from the Microsoft Train Simulator product. For instance:

• Routes provided with an Install.bat file that copies shapes and textures from the routes on the Microsoft Train Simulator CDs.
• Locomotives that re-use cabviews or sounds from the locomotives on the Microsoft Train Simulator CDs (see folder TRAINSET).
• Rolling stock that have sound management (SMS) files that refer to wave files from the Microsoft Train Simulator CDs (see folder SOUND).

If I install Open Rails, will it change my Microsoft Train Simulator files?

Uk Train Simulator Free Download Windows 7

No, Open Rails does not modify any Microsoft Train Simulator files.

Does Open Rails suppport RailDriver?

Yes; this cab controller from P.I.Engineering is suitable for Open Rails and support for it is built in to the simulator. Installation instructions are included in the installation download (and also from this webpage). Eric Conrad has posted a detailed review on his MSTS Roundhouse blog which provides valuable advice for using this product.

Does Open Rails report data back to its creators?

Not at the moment. Data on how Open Rails is used will be very helpful for the project but, if we wish to collect usage data, we will inform you beforehand and you will always be able to opt out.
