How Is Train Speed Measured?

GPS Satellite Signals

Your phone receives signals from multiple satellites simultaneously. By measuring the time signals take to arrive, GPS calculates your precise position.

Doppler Speed (most accurate)

Modern GPS receivers measure the frequency shift in satellite signals (Doppler effect) to derive velocity directly — often accurate to ±0.2 km/h at train speeds.

Haversine Distance Formula

When Doppler speed is unavailable, we calculate distance between GPS positions using the Haversine formula — which accounts for Earth's curvature — then divide by time.

EMA Noise Filtering

GPS data is noisy. We apply Exponential Moving Average smoothing and discard samples with accuracy worse than 200m to show stable, reliable readings.

Full Technical Explanation

How many km/h does a passenger train travel?

Most passenger trains operate between 80 and 200 km/h. Commuter trains run slower (40–80 km/h) due to frequent stops, while intercity services reach 160–200 km/h on main lines.

How fast is 300 km/h in mph?

300 km/h equals approximately 186 mph (miles per hour). Our speed converter lets you instantly convert between km/h, mph, m/s, and knots for any speed.

Can I calculate train speed online?

Yes. TrainSpeedTest.net measures your actual GPS speed in real time. We also offer a speed calculator to compute speed from distance and time, and a unit converter for all common speed units.

What is train speed measured in?

Train speed is typically measured in kilometres per hour (km/h) in most of the world, or miles per hour (mph) in the USA and UK. Railway engineers also use metres per second (m/s) for technical calculations.

Frequently Asked Questions

Everything you need to know about online train speed testing.

How does TrainSpeedTest.net measure train speed?
We use your device's GPS via the browser Geolocation API. Your phone receives satellite position data, which we process using the Haversine formula and apply EMA smoothing to produce accurate real-time speed readings. All processing happens locally — nothing is sent to our servers.
Does it require an app download?
No. TrainSpeedTest.net runs entirely in your web browser on any device — iPhone, Android, tablet, or desktop. Just open the website, grant location permission, and start testing.
How accurate is the train speed reading?
Under good GPS conditions (open sky, above 20 km/h), accuracy is typically ±2–5 km/h. The tool applies filtering to reduce GPS noise and spurious jumps. It is a measurement estimate — not an official railway instrument.
Does it work in tunnels?
GPS signals are blocked by tunnels, so speed readings will pause or show zero inside a tunnel. Measurement resumes automatically once the train exits and GPS reacquires satellite lock.
Is my location data sent to a server?
Never. All speed calculations happen locally in your browser. Your GPS coordinates are never transmitted to our servers or any third party.
What speed units are supported?
TrainSpeedTest.net supports km/h, mph, m/s, and knots. You can switch between units at any time without restarting your trip.
How fast does a passenger train typically travel?
Local and commuter trains typically run at 40–100 km/h. Regional express trains reach 120–160 km/h. Intercity services run at 160–200 km/h. True high-speed trains operate at 250–350 km/h.
What is the fastest train in the world?
In regular commercial service, the Shanghai Maglev reaches 431 km/h. Japan's SCMaglev holds the world speed record for a train at 603 km/h (achieved in testing, 2015).
