On today’s timetable, Barnes (Hounslow) crossing is predicted to be closed for about 12 h 52 min between 06:00 and 22:00, across roughly 83 closures. The longest single predicted closure is 28 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 (00:03–00:06, 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 06:54–07:54 in the morning and around 17:42–18:42 in the evening. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Barnes (Hounslow) is a cctv-monitored manual barrier crossing (CCTV) on the Clapham Junction (C)–Twickenham line (Wessex route · ELR HOU). 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 979 trains through this crossing.
96.4% of observed passes were being warned about on this page when they passed, and 99.2% of the warnings we could verify came true.
Typical timing error was ±33s (9 in 10 within 86s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
