Recorded from 00:01 to 23:58. The figures use the last delay announced at each of the 76,587 stops that had one, as the operator sent it. Cancelled trains (marked cancelled, or with every stop skipped), skipped stops and values over an hour early or twelve hours late are left out, as are 10 placeholder values the feed sent instead of a time (a train “here, now” hours late, or one time repeated at every stop). 100% of the stops of the trains that ran (skipped stops aside) had a delay.
The archive saw 4,805 of the 4,816 trains the timetable planned for this day.
Not counted in the trains planned: 312 more trains the timetable lists on lines the live feed has not carried in the week before (TER).

What the columns mean
service_date- The day the train was scheduled to run.
route- The line, as the operator names it (for example IC 3 or S2).

stop_sequence, stop_id, stop_name- Which stop along the route: its position, code and name.
