On today’s timetable, Naas crossing is predicted to be closed for about 2 h 56 min between 06:00 and 22:00, across roughly 66 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 (02:20–02:21, 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 10:44–11:44 in the morning and around 17:04–18:04 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Naas is a automatic half-barrier crossing (AHB) on the Gloucester–Llanwern Exchange Sdgs 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.
