For everyone’s general amusement, this week the 2107 London Bridge-Uckfield runs ECS back from Uckfield to London Bridge instead of operating in passenger service. This is allegedly to save a few minutes (it’s normally all-stops) to allow a possession to be taken earlier, on the East Grinstead lines north of Oxted somewhere, but nobody has thought to amend the Down trains after this time, which are running as booked until after the 2233 from Uckfield would have run through - and as such the line is staying open for pretty much exactly the same time period. In addition the 2233 from Uckfield is shown on the CIS/journey planners as both a bus (yes) and train (nope).
To cap it all, the stock from Uckfield then sits at London Bridge for half an hour and works the same ECS back to the depot as normal. For further unknown reasons, it leaves behind four coaches at LBG at 2107 and reattaches later. Lastly, the ECS moves for the stock from the 2207 and 2307 Down services both result in significant taxi journeys for the crew, thus longer diagrams.
Much grumbling has resulted from this...
