Check Your Train Speed Online

Want to know how fast your train is travelling? SpeedoLab's free train speedometer lets you estimate your current train speed using your phone's GPS. Start the tool during your journey to view speed readings in km/h or mph, along with your maximum and average speed.

The train speedometer works through GPS, so readings may vary depending on signal quality, your device, and surrounding conditions. It is a speed estimation tool, not an official railway tracking or train running status service.
