A GPS speedometer for trains
A GPS speedometer for trains, with the dial scaled up to 360 km/h (240 mph) so even high-speed rail stays on the gauge. See how fast your train is really going in km/h or mph, with the top and average speed for the trip. Everything runs on your device; nothing is uploaded.
How Train Speedometer works
How fast do trains go?
Commuter trains typically run at 80–160 km/h, intercity services around 200 km/h, and high-speed lines such as the TGV, Shinkansen or CRH reach 300 km/h or more — which is why the dial here goes to 360. This tool reads your phone's GPS to show the real speed as you ride.
Tips for trains
- Sit by a window — GPS struggles when surrounded by metal and in tunnels.
- Start tracking once the train is moving and allow location access.
- Expect brief drop-outs in tunnels and cuttings; the reading recovers when the sky is visible again.

Frequently asked questions
How fast is my train going?
Start the tool by a window and it shows your train real speed from GPS, up to 360 km/h on the dial.
Does it work in tunnels?
GPS is lost in tunnels, so the reading pauses and recovers once you are back in the open.
Is it accurate on a fast train?
Yes — with a clear signal it tracks high speeds well; sit near a window for the best fix.
Do I need an app?
No — it runs in your browser.
Is my location stored?
No — it is processed only on your device.
Is it free?
Yes, completely free.
