As a long time lurker I finally felt it was time to post.
Can somebody explain the purpose of the blockade around Harrow on the Hill over the Easter weekend. The twitter feed suggested it was to do with pointwork and approach speeds?
On my most recent journey on Tuesday there appeared to be many orange people on the track still working (especially on the slow lines north of HotH). There also appeared to be lots of new ballast, some grey cables and some points appear to have been freshly painted white again.
What effects will it have on journeys and/or the timetable and was it in any way connected with the ATC signalling upgrades?
I had noticed the changes (visually) south of platform 5 and 6, but having ridden on a slow train, arriving at platform 6 and changing to the slow line, the train still shakes quite a bit over the points, as before with the scissors.
