Train speed tracker with GPS
Track train speed from your phone using GPS. zigmaty shows live speed, max speed, average speed, distance, elapsed time, GPS accuracy, signal quality, and a chart for the current trip.
Train GPS works best near windows and above ground. Tunnels, stations, metal roofs, and coated glass can reduce signal quality.
Common questions
These answers cover accuracy, privacy, installation, units, and the best way to use this page.
Can GPS measure train speed?
Yes, when your phone can receive a stable GPS signal, it can estimate train speed over the ground.
Why does train speed stop updating in tunnels?
GPS needs satellite visibility. Tunnels, underground stations, and some carriages can block signal.
Can I see max train speed?
Yes. zigmaty tracks maximum speed, average speed, distance, elapsed time, and recent chart readings.
Does it need the train Wi-Fi?
No. Speed comes from GPS location, not Wi-Fi or mobile internet speed.
Can I share a train trip summary?
Yes. Stop the trip and use Share to create a summary of speed, distance, and time.
How to get better results from Train Speed Tracker
Train Speed Tracker is useful as a passenger speed tracker or secondary speed display. Keep the phone where it can see the sky, because roofs, tunnels, stations, and tall buildings can weaken GPS.
zigmaty asks for location only when you start tracking. Speed, alerts, charts, and trip history are calculated locally in this browser.
More questions about Train Speed Tracker
What is the best way to use Train Speed Tracker?
Start outdoors or near a window, allow location, wait for a stable GPS signal, and keep the phone secure while moving.
Why can the speed reading change suddenly?
GPS speed can jump when signal is weak, the browser updates slowly, the phone enters battery-saving mode, or buildings and tunnels block satellite visibility.
Can I use Train Speed Tracker for official speed or navigation decisions?
No. zigmaty is a browser utility, not a certified dashboard, navigation system, or safety instrument.
