Railsim is one of the oldest train simulators I own, and it looks even older. However, it is still one of my favorites. In this playthrough, I try out the fictional Redwood-Blacktown commuter route (in the USA/CAN version of the simulator) with a freight train headed by 4 SD40-2 diesels.

Railsim can still be downloaded from:

Jens Schubert has since developed a sequel known as ZUSI available here:
