BAHN is a simulation of large rail networks (High speed service Germany, Metro Paris or London or larger). You can choose from over 9000 different rail vehicles from the world. While running the simulation, you can build new lines and edit existing ones, even when running some hundreds of train simultaneosly. The traffic can run scheduled or by random, or both combined. In the Internet you can find hundreds of example layouts. Remark about shipping "via E-Mail": After registration, the registration data are sent only, not the complete software.
