Train Journey Average Speed Calculator

For a train journey, measure average speed from distance and elapsed time using your entered values.

How to use Train Journey Average Speed Calculator

1. Enter Distance, Elapsed Journey Time, Distance Unit. 2. Use an entered rail distance and overall average for the chosen journey. Station waits, transfers and timetable availability are not added automatically. Kilometres pair with km/h and miles with mph. Changing the selector labels existing inputs; it does not convert them. 3. Select Calculate or press Enter. 4. Select Copy result to copy the answer, or Reset to clear the form and result.

Why use this tool?

Compare train journey planning assumptions on one consistent distance and time basis.

How the calculation works

Average speed = distance ÷ positive elapsed time in hours. Use an entered rail distance and overall average for the chosen journey. Station waits, transfers and timetable availability are not added automatically. Kilometres pair with km/h and miles with mph. Changing the selector labels existing inputs; it does not convert them. Durations round to the nearest second; other quantities round to at most six decimals (percentages to two). Nonzero subprecision values are identified.

Example

Worked example: Distance = 225; Elapsed Journey Time = "2 h 30 min"; Distance Unit = "kilometres". Result: 90 km/h.

Practical tip

Use distance and time measured over the same interval, with the same decision about including stops.
