You're a trackman who's terribly busy. There are so many trains on the track, and they're all in a hurry. Regulate the train traffic in such a way, that the trains don't collide. By clicking on the signals, you make them turn red or green. By clicking on the switches, you turn them and make the trains change tracks. You earn extra money by making the trains stop at the train station. Do your best and let the trains arrive at their destination without colliding!
