About this app

🚃 How fast is the train I'm on going right now?

The scenery passing by outside the window, the feeling of acceleration on your body—
"I wonder how fast this train is going right now?"

Answering that question in real time with just GPS, the "ImaTetsu Speedometer" is a GPS speedometer specifically for trains.

It works on Shinkansen, limited express trains, and conventional lines. It automatically recognizes the route and displays the distance to the next station,
a timeline of all stations, and a speed graph. It makes train travel, trips, and family outings even more enjoyable.
