Each run is closed into train_runs (country, train number, service day) from the live positions. Final delay = last delay seen. Partial coverage: the feed stopped before the final stop (last value used, hatched in the chart). No data: a run without any valid delay; counts as neither on time nor late. Data collected since 11 July 2026.
