Train Speed Test

See how fast your train is really moving. From suburban commuter rails to 300 km/h high-speed trains (TGV, ICE, Shinkansen, Frecciarossa), read your live speed right from your passenger seat.

How it works

Measure High-Speed Rail Velocity

  1. 01

    Take a Window Seat

    Rail car metal frames shield signals; window glass allows satellite reception.

  2. 02

    Start Tracking

    Activate the speedometer before the train accelerates out of the station.

  3. 03

    Watch Top Speed

    Observe high-speed cruising speeds between major cities.

Technical Details

GPS Through Train Windows & In Tunnels

How modern train design affects GNSS satellite reception.

Coated Thermal Glass

Modern high-speed trains often use metallic heat-reflective coatings on windows that attenuate radio signals; placing your phone directly against the glass helps signal lock.

Tunnel Dead Reckoning

GPS signals cannot pass through mountain tunnels. SpeedReflex filters tunnel exits so position jumps do not corrupt your genuine max speed.

FAQ

Train Speed Test FAQ

Does GPS work on high-speed trains?

Yes. Satellite GPS receivers have no trouble tracking velocities up to 1,000 km/h. Keep your phone near the window for optimal reception.

Why does speed drop to 0 in tunnels?

Mountain tunnels block line-of-sight satellite signals. The speedometer will re-acquire your true speed within seconds of exiting.
