Check Your Train Speed

See exactly how fast your train is moving with a live GPS speedometer. Works on suburban services, intercity expresses, and high-speed rail — right from your seat.

Typical train speeds

Commuter / suburban
60 – 120 km/h
Intercity / regional
120 – 200 km/h
High-speed (TGV, Shinkansen, ICE)
250 – 350 km/h

High-speed rail and GPS

High-speed trains can comfortably exceed 300 km/h on dedicated lines like the French TGV, Japanese Shinkansen, German ICE, or Chinese CRH. Because they run mostly above ground in open terrain, GPS reception is excellent and the dial above is calibrated up to 350 km/h.

Why the train ride feels slow

A modern long-distance train can hold a steady 200 km/h that feels quite gentle — far smoother than a car at the same speed. Watching a precise GPS speedometer is a nice way to appreciate just how fast you are actually moving compared to the landscape outside.

Tunnels and rural areas

GPS works fine in open countryside, which is where most fast train sections run. In long tunnels (Channel Tunnel, alpine base tunnels) you will lose the signal entirely until the train exits — that is expected, not a bug.

Tips for an accurate train speed reading

  • Sit by a window. The metal coach body and reflective glass coatings can sometimes weaken GPS signals — being closer to the window edge helps.
  • Allow 10–20 seconds after starting the test for the GPS to lock on, especially right after leaving a station.
  • For commuter trips, reset the trip just before the doors close at your origin station for a clean average.
  • On high-speed routes, the analog dial display gives a more dramatic, glanceable readout than the digital number.
  • In a tunnel, the speed will drop to zero — that is normal; it will resume once the train exits.

Frequently Asked Questions

It depends on the line and rolling stock. Suburban trains usually peak around 100–140 km/h, intercity services 160–200 km/h, and dedicated high-speed lines often run at 250–320 km/h in service. The GPS speedometer will show the actual figure for your specific train.

Yes, on the open sections of track. In tunnels (including the Channel Tunnel and many high-speed mountain sections) you will lose the signal until the train exits, which can be several minutes.

GPS itself stays accurate at high speed; the limiting factor is usually how often your phone’s GPS chip refreshes (typically once per second). The figure may bounce a little but will average to your real train speed.

It can attenuate it. Modern train windows are usually GPS-friendly, and sitting close to the window is enough. If the signal is poor mid-coach, just move closer to a window for a stronger lock.
