Possible they're keeping it to cover for teething issues (given they're new, it'll be a case of waiting for ADL to fix any issues under warranty so might not be as quick as a depot could do it), or for the entry into service of their deckers (I've not seen any of 7515/6/53/54 in service there, and 7556 is/was dead at Ashington last week).
2837 is the only one of Northumbria’s M950s being retained - the 555 doesn’t enter the CAZ zone so does not need to be operated by a Euro6 vehicle. Likewise, 2601-3 are being retained for the 553 for the same reason.
