On today’s timetable, Gaerwen crossing is predicted to be closed for about 3 h 50 min between 06:00 and 22:00, across roughly 50 closures. The longest single predicted closure is 6 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.
Closures cluster around 07:26–08:26 in the morning and around 20:02–21:02 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Gaerwen is a manually-controlled barrier crossing (MCB/MB) on the Bangor (Gwynedd)–Bodorgan line (Wales route · ELR CNH3). A signaller monitors the crossing, confirms it is clear, and lowers the barriers ahead of each train. 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.
