Background
Rail fan is based on the Train Simulator engine, and has a tourist mode to provide extra thrills as you travel around Japan and Chicago.
Gameplay
There are three rail systems to play on in Railfan. Some of Tokyo's JR system is modelled in the game, as is a track from Kyoto to Osaka. Chicago's Brown line is also included. The goal of the game is to run the train properly by making sure you get to your stops on time and stop properly at each one.
