is a small railway simulation game. You are in control of a small section of track, and must ensure that as many trains get through the section as fast as possible. To control the trains you set the points in the section of track to redirect and halt trains.
There are three different levels of difficulty in the game. On the more difficult levels you have to get some trains through faster than others, or you have to direct trains to follow certain routes. If you do not follow the given route or cause these trains to wait for too long, you'll lose points. The game ends if you allow two or more trains to collide.
Main Line features game save, high scores, sound effects, and more.
