On today’s timetable, Traeth Mawr crossing is predicted to be closed for about 46 min between 06:00 and 22:00, across roughly 17 closures. The longest single predicted closure is 2 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 (06:53–06:55, 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 06:50–07:50 in the morning and around 17:56–18:56 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
The crossing is on Snowdon Street in Porthmadog, Gwynedd, next to Gelert's Farm station.
Traeth Mawr is a automatic barrier locally monitored crossing (ABCL) on the Minffordd–Pwllheli Station Sidings line (Wales route · ELR DJP). 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.
