You'd still have to do Newcastle and back in less than 2 hours unless there was an interworking somewhere. Remember the allocation then was generally a couple of NCP2 Olympians or a B10BLE thrown in - both more capable than an E400.And that is why the X19 would interwork with the full X21's. This is what the interworking pattern would look like
Full X21s
- X22 Ashington 0025 > Newcastle 0123
- X21 Newcastle 0130 > N'Biggin Cresswell Arms 0245
- X19 N'Biggin Cresswell Arms 0259 > Newcastle 0401
- X19 Newcastle 0408 > N'Biggin Cresswell Arms 0510
- X21 N'Biggin Cresswell Arms 0521 > Newcastle 0638
- X22 Newcastle 0645 > Ashington 0742
then...........
Short X21s
- X22 Ashington 0755 > Newcastle 0853
- X21 Newcastle 0900 > Ashington 0957
- X21 Ashington 1010 > Newcastle 1108
- X22 Newcastle 1115 > Ashington 1212
