Automatic half-barrier level crossing on the Wales route (ELR SWM2).
| No trains in the next 30 minutes. |
On today’s timetable, Naas crossing is predicted to be closed for about 3 h 35 min between 06:00 and 22:00, across roughly 79 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 08:17–09:17 in the morning and around 19:17–20:17 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.
We score this page against what actually happened on the railway — over the last 7 days that covered 1 trains through this crossing.
100.0% of observed passes were being warned about on this page when they passed, and 96.5% of the warnings we could verify came true.
Typical timing error was ±48s (9 in 10 within 48s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
