XurChooChoo by TheLunarCraft is a game where you must ensure that a set of trains can pass through correctly by means of changing the orientation of the train tracks.

Gameplay

You start the game with a set of 2 tracks perpendicular to each other, forming a crossing/junction. The central track is on top of a light signal. Tapping the screen will place the track down.

To change the track orientation, tap the screen. This is the only entity that can be altered. A light in the middle will indicate the direction from which the subsequent train will come (green means a train is coming, red means it is not). Note that the train can come from either side of the junction.

A point is added anytime a train successfully crosses the junction. The trains come one at a time, so there is no danger of collision. The game gets more difficult as the frequency of trains crossing increases. The game ends when you fail to align the central train track properly, causing the train to crash.
