Frequently asked questions
How do I check my train's speed?
Open this page on your phone, sit near a window for the best signal, and tap Start. Your live speed appears in km/h or mph, and the top speed of the journey is recorded. Everything runs in your browser — your location never leaves your device.
Does GPS work inside a train?
Yes, usually well — trains have large windows and travel through open country, so the signal is often strong. It can drop briefly in tunnels or between tall buildings, then recovers. Sitting by a window helps.
How fast do trains actually go?
It varies widely — many intercity trains cruise around 110–160 km/h, express and high-speed services can reach 200–320 km/h, while local trains are much slower. This tool shows your train's real speed as you travel.
Is it accurate on a train?
With a clear view through the window, GPS speed is typically within a few km/h. It's a great way to see how fast you're really moving during the journey.
