Mortlake level crossing

How often it closes

On today’s timetable, Mortlake crossing is predicted to be closed for about 13 h 24 min between 06:00 and 22:00, across roughly 65 closures. The longest single predicted closure is 39 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: 6.8 min (00:01–00:08, 2 trains), 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.

Worst times to cross today

Closures cluster around 07:10–08:10 in the morning and around 15:08–16:08 in the afternoon. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.

About this crossing

Mortlake is a cctv-monitored manual barrier crossing (CCTV) on the Barnes–Twickenham line (Wessex route · ELR RDG1). A signaller monitors the crossing, confirms it is clear, and lowers the barriers 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 2,053 trains through this crossing.

100.0% of observed passes were being warned about on this page when they passed, and 99.3% of the warnings we could verify came true.

Typical timing error was ±31s (9 in 10 within 90s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
