This is one fun train game. You drive your polar express train along the tracks and you pick up additional train-cars. You do that when you change the red-green switch and change the path of the train. Lead your train to where you want it and avoid crashing. You will crash if you do not change the switch on time. You can also control the speed of the train and you can brake by using switches in the lower part of the screen. If you need additional info you can find it inside the game. Keep in mind at all times, passenger safety is above all!
