The OpenBVE Project

This site is the home of OpenBVE - a license-free, open source, free of charge train driving simulator.


This program includes detailed per-car simulation of the brake systems, friction, air resistance, toppling and more. In 3D cabs, the driving experience is augmented with forces that shake your simulated body upon acceleration and braking, as well as in curves. Besides that, OpenBVE features a 3D positional sound system best enjoyed with surround speakers, 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.

Compared to other simulators of the genre, especially compared to commercial games, OpenBVE has its main focus on realism, not necessarily on user-friendliness. You should be willing to study operational manuals for the routes and trains you want to drive, and will in many cases not get along by just memorizing a few keystrokes. If you can identify with this focus, OpenBVE might be the right simulator for you.

You can obtain the OpenBVE program software free from this site along with instructions & information.
All celtictrainsim routes and trains are compatible with the program from here. It is recommended that users of earlier program versions update to this build for trouble free operation of cts products.

In addition to information for users of the sim there is also documentation and information to those involved in creating content (route  and train files) as well as a discussion board, where problems may be resolved.
It is recommended that users visit this site for all info and queries regarding the use of the sim program, although queries concerning specific route/train items should be addressed to that item’s provider, whenever possible.

Further help, if needed, may be available by visiting user forums. A recommended one is BvE Worldwide which is free to register and use. Visit http://bveworldwide.unlimitedboard.com/
