On today’s timetable, Duncrun crossing is predicted to be closed for about 2 h 30 min between 06:00 and 22:00, across roughly 30 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.
Closures cluster around 07:03–08:03 in the morning and around 12:00–13:00 in the middle of the day. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Duncrun is a automatic half-barrier crossing (AHB) on the Castlerock–Bellarena line (NI Railways route). 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.
