On today’s timetable, Bollo Lane (Kew line) crossing is predicted to be closed for about 9 h 48 min between 06:00 and 22:00, across roughly 109 closures. The longest single predicted closure is 14 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 (00:11–00:14, 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 06:32–07:32 in the morning and around 15:33–16:33 in the afternoon. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Bollo Lane (Kew line) is a cctv-monitored manual barrier crossing (CCTV) on the Willesden Jn. High Level–Gunnersbury line (Anglia route · ELR BOK5). 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 496 trains through this crossing.
99.4% of observed passes were being warned about on this page when they passed, and 99.9% of the warnings we could verify came true.
Typical timing error was ±21s (9 in 10 within 73s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
