On today’s timetable, Pontsarn crossing is predicted to be closed for about 4 h 30 min between 06:00 and 22:00, across roughly 105 closures. The longest single predicted closure is 4 minutes. Freight paths scheduled “as required” — most don’t run on any given day — aren’t counted here; when one does run, the live timeline above shows it.
Longest closure so far today: 1.5 min (00:03–00:04, 1 train), timed from trains actually seen on the signalling wire — the window edges use the same per-type margins as the forecast, since barrier positions aren't in any feed we can read.
Closures cluster around 08:15–09:15 in the morning and around 16:25–17:25 in the afternoon. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Pontsarn is a automatic half-barrier crossing (AHB) on the Ninian Park–Bridgend line (Wales route · ELR SWM2). The approaching train itself triggers the closure at a fixed point on its approach. Forecasts here combine the working timetable with live train-movement data (and live signalling where the crossing has it), so they reflect actual running including delays and freight — though they can still be wrong when the network is disrupted.
We score this page against what actually happened on the railway — over the last 7 days that covered 6 trains through this crossing.
100.0% of observed passes were being warned about on this page when they passed, and 100.0% of the warnings we could verify came true.
Typical timing error was ±12s (9 in 10 within 99s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
