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.
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.
