On today’s timetable, Blackboy Lane crossing is predicted to be closed for about 5 h 36 min between 06:00 and 22:00, across roughly 120 closures. The longest single predicted closure is 4 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: 4.8 min (13:31–13:36, 3 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.
Closures cluster around 07:43–08:43 in the morning and around 14:17–15:17 in the afternoon. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Blackboy Lane is a automatic half-barrier crossing (AHB) on the Chichester–Havant line (Sussex route · ELR TBH2). 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.
We score this page against what actually happened on the railway — over the last 7 days that covered 1,101 trains through this crossing.
100.0% of observed passes were being warned about on this page when they passed, and 98.4% of the warnings we could verify came true.
Typical timing error was ±3s (9 in 10 within 120s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
