Train Chains

Trains roll out of the tunnel, each painted in a station's color. You run the switches. One tap flips a switch; the solid branch with the arrow is where the next train goes. Send every train to the station of its own color, and keep the yard moving as the trains speed up.

Easy to learn, hard to put down. Every run starts calm and gets faster with every few deliveries. Three wrong stations and the run is over; one tap and you're back on the line.
