Open the Speed Test on Your Phone
Use a modern mobile browser and open CheckTrainSpeed.com while you are travelling. The tool works without installing an app or creating an account.
Allow Location Access
Tap Start and allow location permission when your browser asks. GPS movement data helps calculate live speed, top speed, distance and trip time.
Keep the Phone Near a Window
Train roofs, tunnels and stations can weaken satellite visibility. A window seat or open route usually gives better GPS accuracy.
Read the Dashboard
The live speed meter shows current speed in km/h. The side cards show top speed, average speed, distance, trip time and GPS accuracy.
