Back in July, service 86 was revised to operate between Concord and The Galleries only (and hence the PVR of service 86 reduced to 1 vehicle, from 2). 705 was hence released for cascade back then, but used at Washington until 3rd September on a Miscellaneous Works board, so a double-deck vehicle could be released to Riverside for Metro Replacement.

As soon as the content of this Miscellaneous Works board was lost entirely on 3rd September, it was no longer required at Washington (which is why 705 transferred to Peterlee at the weekend).

So two spares for the X1 (currently 6141/42) - as before - with 3943 being allocated to scholars 885 and a peak-time X1 run.
Three spares for the 4 and 5/50 (5324, 5337 and 5338) - as before.
One spare for the indiGo Washington network - as before (but now covering a smaller PVR, so a higher spare vehicle percentage overall).

The B7TLs withdrawn from Washington are removed from the fleet as a result of the loss of Miscellaneous Works contracts, so no need for them to be replaced.
