Hi all, just a few mild and minor curiosities based on some things I saw whilst out yesterday.
Firstly, an engineering train during the day: presumably not super rare, but a first for me other than at an active work site. I saw this on platform 5 at Harrow on the Hill at around 1130. It was signalled onto the southbound fast/main line after a brief stop in the platform. I was talking to a member of staff at the time who made a few suppositions, firstly that the train may have been en route to Watford and secondly that although such a movement would typically reverse south-north via the siding, it may have been that yesterday control preferred to reverse it at Neasden due to perturbation at the time caused by a signal failure at Eastcote. Could anybody shed any light? I saw the train heading back north between Preston Road and Harrow at around 1145, and then again heading southbound through Harrow, sometime around 1300.
A little while after this I travelled from Harrow to Uxbridge and back, and my travelling companion and I were curious as to whether we might see the engineering train for a fourth time, heading back in to Ruislip depot. The siding was very much empty when we travelled past westbound, but on the return leg I was somewhat surprised to see it occupied by a 72 stock train. Once again, could anybody shed any light? I am aware that overhaul work is taking place on this fleet and I am quite sure I recall hearing that this is happening at Acton. However, what I am almost certain of is that the actual transfer of units on or off the Bakerloo line has to take place outside of traffic hours, as it would involve units travelling over the Jubilee line with it’s incompatible signalling. Hence, the appearance of a unit in the siding so far ahead of the end of service is/was a bit puzzling. Without wanting to get ahead of myself in case there is a quite different explanation, I would have thought that siding sees fairly regular use for service recovery reasons, as well of course access to/from the depot, even if there are no longer any booked reversals. Surely therefore they wouldn’t have left the 72 there until a move 10 or so hours later??
As always, many thanks in advance
