Be thankful for ferrous panels and fridge magnet technology. Trying to label aluminium or plastic faceplates would be a real nightmare. Post-it notes would have to do.

The TEW panels are plastic but have a steal plate glued on the inside so the fridge magnet technology will still work, but for some reason it doesn't work on VDU's :lol:

VDUs need Tip-Ex or Snopake, but we are drifting away from Luton.

Thanks for all your replies, general as well as specific.

TBW between Harpenden and Leagrave - does that mean the cross-overs both ends were usable as normal, with effectively temporary plain line between them?
Was it one block section for the whole 8 miles? If so, with a 25 minute transit time, that means max 2 TPH on each line, and any attempt to run more than that would be doomed to fail.
The transit time suggests trains had to stop at each signal and either speak to someone on the ground or to the signaller. Why is that necessary, when there is known to be no signalling throughout the 8 miles? If non-stop passage is allowed, then the transit time should be a little over 10 minutes, at 50 mph. If a stop at each signal is required, then there is little prospect of exceeding 50 mph, to answer RobMorel.

John Webb at St Albans reports that the turn-back siding was still in use on Wednesday afternoon. That doesn't fit with what I saw later in the week from the south - nothing running north of Blackfriars (from Sutton) / City Thameslink (from Brighton). Did GTR just give up and try to blame NR infrastructure damage far more than was needed?

crossovers at both Harpenden and Leagrave junction fully available so block section station to station affected trains stop on entry to collect movement authority ticket and stop at the end to surrender it, signals in between can be ignored
3 trains an hour (2xTL, 1 X EMT) just about worked with skip stopping at stations whilst maintaining a service at Luton Airport Parkway
As to St Albans centre siding, throughout the incident a 'splii' service North and South was brought in with some extra services Kentish Town to St Albans
- More on the lost art of the handsignaller -
