openBVE, a license-free, open source, free of charge train driving simulator, which is intended to be compatible with routes and trains developed for an existing simulator called BVE Trainsim. However, openBVE features unique extensions and will be further expanded at the wish of the community beyond mere compatibility. The simulation is being developed primarily for Windows, but support for Linux and Mac is also being prepared.
With the current versions, you can use most of the material ever written for BVE 1, BVE 2 and BVE 4 with only minor differences in reproduction and behavior. Physics-wise, openBVE includes detailed per-car simulation of the brake systems, friction, air resistance, toppling and more. Besides that, openBVE features a 3D positional sound system best enjoyed with surround speakers, some versions of the Japanese safety systems ATS-SN, ATS-P and ATC, train exteriors and timetables for the current run. Finally, via the main menu, routes and trains be easily selected to start a new session, the controls can be configured to keyboard or joystick devices and a variety of options can be selected.
Operating system: Windows XP, Vista, 7, Linux, or Mac OS X
Mono, a .NET implemention, and OpenAL, an audio library for positional 3D sound are required.
