When the Deltas 4801/3-7 Go Xpress where operated at the start it was Deptford but then they got moved to South Shields depot for operation of the 2 services and I believe that was when they definatley went downhill as Shields had no interest as they knew they were for imminent closure..
I think the X50 was standalone for a short while and operated by Chester, after the original X20 ended.
