On today’s timetable, Marston crossing is predicted to be closed for about 1 h 16 min between 06:00 and 22:00, across roughly 35 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 (05:43–05:44, 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 07:29–08:29 in the morning and around 19:14–20:14 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Marston is a automatic half-barrier crossing (AHB-X) on the Bletchley–Millbrook (Bedfordshire) line (West Coast South route · ELR BBM). 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.
