Crossing & Train is an Android application developed by TKG研究所. It falls under the Lifestyle category and offers a simple train simulator experience for all train enthusiasts. The game is easy to play and can be operated by one finger. There are no game factors involved, making it a stress-free experience.

The gameplay is straightforward. When you tap the screen, a train passes by. The objective is to see and enjoy the train as it passes. As the train passes, a meter in the upper right corner of the screen increases. When the meter reaches its maximum, the level increases. It's worth noting that when the level increases, something good may happen, although it's unclear what that something is.
