On today’s timetable, Liss crossing is predicted to be closed for about 6 h 4 min between 06:00 and 22:00, across roughly 83 closures. The longest single predicted closure is 6 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: 5.8 min (00:49–00:55, 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 07:13–08:13 in the morning and around 15:48–16:48 in the afternoon. Gaps between closures are longest outside those windows. Other days run a different timetable, so the peaks move.
Liss is a cctv-monitored manual barrier crossing (CCTV) on the Haslemere–Petersfield line (Wessex route · ELR WPH1). 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 728 trains through this crossing.
100.0% of observed passes were being warned about on this page when they passed, and 100.0% of the warnings we could verify came true.
Typical timing error was ±146s (9 in 10 within 176s). This scores when trains pass — barrier movements aren't in the public feeds we can score against.
