In this game, player guides a train to pick up the exact resources and deliver them to the factory in the order exactly as requested within time limit. This is done by switching the tracks, signaling a train to go through or stop, and picking up the resources in the correct order. The train will only load up one cart at each resource. If the player picked up a wrong cart, he can click and remove it when the train stops. Passenger trains may enter the tracks from time to time, and it is up to the player to guide them to their destination safely. The game is over if the player causes a crash or runs out of time. Complete all levels to finish the game.
