Stops and timetable
Timetable of the latest run from the operator’s GTFS (3 stops).
Last 90 days, 44 runs. At intermediate stops it is an estimate from the delay at origin and destination. Delays over 2 h count as “> 2 h”: our data does not measure them exactly.
| Stop | Sched. | Usually | 9 days in 10 |
|---|---|---|---|
| 21:38 | on time | on time | |
| 21:57 / 21:58 | ≈ on time | ≈ +1 min | |

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.
