Automatic half-barrier level crossing on the Wales route (ELR SBA2).
| No trains in the next 30 minutes. |
On today’s timetable, Ynyslas crossing is predicted to be closed for about 1 h 17 min between 06:00 and 22:00, across roughly 29 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 (00:22–00:24, 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 10:48–11:48 in the morning and around 20:18–21:18 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Ynyslas is a automatic half-barrier crossing (AHB) on the Down–Aberystwyth line (Wales route · ELR SBA2). 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 171 trains through this crossing.
99.4% of observed passes were being warned about on this page when they passed, and 96.1% of the warnings we could verify came true.
Typical timing error was ±376s (9 in 10 within 630s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
