Train Clock

This is an app that helps you learn how to read a clock. The minute hand is a Shinkansen, the hour hand is a conventional train, and the second hand is a steam locomotive. The trains are displayed randomly. When you tap the Shinkansen icon at the bottom of the screen, the Shinkansen used as the minute hand changes to another Shinkansen. When you tap the conventional train icon, the train used as the hour hand transforms into another train. At the top of the screen, trains stop at a station at random. Every two minutes, a train departs.
