About Late Trains

What's here

Per-train history built from recorded station arrivals — reported by Pakistan Railways' own systems, and by GPS where those are missing: typical (median) delay, on-time percentage, day-of-week patterns and per-station breakdowns, alongside the published timetable for each service.

How a delay figure is made

• Collect — a collector polls the public live feed on a fixed interval and archives every response verbatim, append-only, before any processing. Every later figure is recomputable from that archive.
• Arrivals from Pakistan Railways — where the feed reports a station arrival and its delay, that is stored as given, labelled on the page as coming from Pakistan Railways' own record.
• Arrivals from GPS — for the rest of the journey, the train's GPS trail is compared against station locations. Entering a station's geofence stamps the arrival time for that service date. This path depends on the upstream GPS feed, which goes quiet from time to time — recorded arrivals do not stop when it does.
• Compare to the timetable — arrivals are matched to the schedule in force on that date. Timetables are versioned, so a schedule change does not re-score older history. The difference is the delay shown on every train page.

Statistics appear for a train once it has at least a week of usable history. When the upstream GPS feed goes quiet, GPS-derived arrivals pause and resume on their own; gaps stay gaps. Operator-reported arrivals are a separate path and are not affected by a GPS outage.
