I hope this doesn't happen, but:
6001 & 6002 - Chester Le Street allowing 3962 & 3965 to transfer to Percy Main for the 327. This will allow Go North East to withdraw 3866 & 3867. 6003, 6004 & 6005 - also to Chester Le Street, so three more Lolynes can be withdrawn. 6006 & 6007 - Riverside so two of either 3818/19/24. 6049 - Riverside and branded for the TTX meaning 6084 could be branded for the TEN services. 6050-55 - Stanley - help wiithdraw the Lolynes and Olympians. 3943 - Stanley along with 6050 - 6055.
16x E400MMC for service X1, with 2 acting as spares, and one could be allocated to service X88 on the weekends.
