How we measure

On time: under 5 min

A train counts as on time if it is less than 5 minutes late at its next station. Trains without live data are not counted.

Within 15 min

The broad threshold, close to what most operators report: the share of tracked trains less than 15 minutes late.

Every minute

Every minute, the state of each tracked train is recorded; the day is the average.

A usual day

The comparison is with the average of the four previous same weekdays, as soon as two of them have been measured.

On a route

Delay counts on arrival at the final stop, once the train has arrived. Both directions are combined.

And the operators?

Deutsche Bahn counts a train as on time when it is less than 6 min late. Their figures therefore do not compare directly with ours.
