Manual gate level crossing on the Western route (ELR SWM1).
| No trains in the next 30 minutes. |
On today’s timetable, St. Mary's crossing is predicted to be closed for about 2 h 34 min between 06:00 and 22:00, across roughly 37 closures. The longest single predicted closure is 3 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: 3.2 min (00:49–00:53, 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 07:37–08:37 in the morning and around 17:47–18:47 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
St. Mary's is a manual gate crossing (MGH) on the Swindon–Stroud line (Western route · ELR SWM1). A signaller or crossing keeper closes the gates across the road 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.
We score this page against what actually happened on the railway — over the last 7 days that covered 120 trains through this crossing.
100.0% of observed passes were being warned about on this page when they passed, and 99.5% of the warnings we could verify came true.
Typical timing error was ±68s (9 in 10 within 150s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
