Check Your Metro Speed

Find out how fast your metro, subway, or underground train is moving between stations. The speedometer locks on whenever the train surfaces or runs above ground.

Typical metro speeds

Between busy stations
30 – 50 km/h
Longer interstation gaps
50 – 80 km/h
Express / outer sections
80 – 100 km/h

Metros, GPS, and tunnels

Many metro systems run entirely underground, where pure GPS does not reach. Whenever the train surfaces — bridge crossings, elevated sections, ground-level interchanges — your phone re-acquires a fix and you will see the live speed. Above-ground lines (like parts of London’s District line or Paris RER) give a complete journey reading.

What metro top speed feels like

Most modern metro stock is governed to around 80–100 km/h. That sounds modest compared to mainline trains, but inside a metro tunnel it can feel surprisingly fast because of the narrow walls flying past your window.

Why the average matters

On a stop-heavy line, the train might peak at 80 km/h but average only 30 km/h door to door. Watching the average climb between stations gives a much better sense of how "fast" a metro line really is.

Tips for an accurate metro speed reading

  • Sit near a window or near the front of the train where GPS can pick up more clearly during surface sections.
  • Reset the trip just after the doors close at your starting station for a clean average between stations.
  • On fully underground systems, the speedometer will only update when the train briefly surfaces — that is expected.
  • Keep the screen on by tapping occasionally — most browsers pause Geolocation when the screen turns off.
  • For elevated lines (e.g., Chicago "L", Berlin S-Bahn) you will get near-continuous readings throughout the journey.

Frequently Asked Questions

GPS signals come from satellites and can’t reach you below ground. The readout drops to zero until the train surfaces again. This is a limitation of any phone-based GPS speedometer, not a problem with our app.

Most metro systems top out around 80 km/h, with some modern stock (Singapore MRT, Beijing Subway, Paris Line 14) capable of 90–100 km/h on longer sections. Older systems may cap closer to 60–70 km/h.

Yes — light rail and trams run above ground, so GPS works the whole time. The speed range is similar to a metro, often topping out around 70 km/h.

No. GPS uses satellites, not mobile data. Once the page has loaded, the speedometer keeps working even when the train is between cell sites underground.
