In addition, I have seen photos of some of the 22072-22082 batch working on the "E" services during the Volvo B10BLE era.
That wouldn't require the entire South Shields screen list to be loaded into the Sunderland fleet.
Incidentally, the Stockton fleet have Hartlepool routes programmed into the screen list - however only the 1 (with very basic screens) and the 7 (with proper screens)
