Ever wondered "how fast is my train going?": now you can know instantly. Free GPS train speed checker, no app needed. Works on any rail service worldwide.
Tap Start GPS and allow location access
Open this page, tap Start GPS and keep your phone near the window. The train speed test shows the current speed of your train in km/h or mph, updated every second, together with the top speed and average speed of the journey so far.
Switch units with the buttons under the gauge. Most passengers in India and Europe read train speed in km/h, while mph is standard in the UK and US. Knots and m/s are there too if you need them.
| Type of train | Typical speed |
|---|---|
| Metro and suburban | 30 to 80 km/h |
| Express and mail trains | 60 to 110 km/h |
| Semi high-speed (for example Vande Bharat) | Up to 160 km/h on approved sections |
| High-speed rail (bullet trains in Europe, Japan, China) | 250 to 350 km/h |
Tunnels, deep cuttings and metal carriages can block GPS for a short time. The reading recovers on its own once the signal returns. Mobile data is not needed after the page has loaded, as explained in does GPS work on trains?
Travelling by road instead? Use the bus speed test or car speed test.
To run a train speed test, tap Start GPS above and allow location access. Your phone reads its position from satellites and this page converts it into live speed, so you can see the speed of your train in km/h or mph within a few seconds. No app, no sign-up, and it works on any rail service in the world.
Train operators don't always display speed for passengers. The train's control cabin shows it, but the passenger saloon typically doesn't: unless it's a premium service with a travel screen. That's where this free train speed test comes in.
On a smartphone, your GPS receiver queries satellites every 1–2 seconds to calculate your precise position. From consecutive positions, this GPS train speedometer derives your speed. On high-speed rail this means you can watch the speed climb past 200, 250, even 300 km/h in real time, right from your seat.
In long underground tunnels, GPS signals are blocked by hundreds of metres of earth and concrete. The displayed speed will hold at the last known value or drop to zero. Once the train exits the tunnel, the receiver reacquires satellites within a few seconds and accurate readings resume.
The fastest commercial rail services currently operate in China (CRH380A at 350 km/h), France (TGV at 320 km/h), and Japan (N700S Shinkansen at 285 km/h). The absolute speed record for a rail vehicle is 603 km/h, set by the SCMaglev in Japan in 2015.
Yes, in most cases. This train speed checker uses your phone's GPS, which works through train windows to reach satellites. Long tunnels or reinforced roofs on underground sections may block the signal temporarily: readings resume once the train re-emerges.
High-speed trains like the TGV, Shinkansen, and CRH reach 300–350 km/h in service. Some test runs have exceeded 570 km/h.
Above-ground and elevated metro sections work well. Underground tunnels block GPS signals, so readings will freeze in those segments.
GPS requires line-of-sight to satellites. Underground tunnels block those signals entirely. The speedometer holds the last known speed or shows zero until the signal returns.
Using your phone for personal speed tracking as a passenger is legal virtually everywhere. Always follow any device-use rules posted by the train operator.
