So I've mentioned previously that it's possible for Derwentside's low height PVR to be reduced only to 4x and with same overall PVR of 17x and no major route changes.

If the X10 was increased to half hourly NCL-Peterlee (or X9 reintroduced), would it not make sense shifting all E400MMC to Riverside and have the following to sort the vehicle shambles out?

- X10 (NCL - Peterlee increased to half hourly) - PVR 6x

- X21 standalone (4 boards) - PVR 4x

- X21 (4 boards) /X71/X30 - PVR 8x, driver reliefs at Gateshead, NCL bound driver does X21>X71>X71>X30>X30>X21 with southbound driver doing round trip to West Auckland

Would be risky interworking the X21 with X30 & X71, but layover time in Consett would be 23 minutes so any delays could be recovered.

Would require 17x E400MMC with 6377 also used on the X10 and still leave 3x spare E400MMC. Also not forgetting, that the low height PVR would only be 8x. So full height deckers if needed could still be allocated to the X10 and the 4x standalone X21 boards.

Then for Consett, they get the 12 back in place of losing the X30 & X71 (interworking with the 6 - PVR 9x) and all E200MMC based out of Consett with the X66 getting a stop-gap until the EV's arrive. Then obviously 6356-63 and 6308-14 (with X20 getting a stop gap until cascaded B9TLs available) do the X32/X45/X70/X73 (PVR 13x) with 2x spares available.
