Very much one of those services where 'anything goes'. Same goes for the other two as well.

DAF deckers would encompass both Lowlanders and ALX400s so its not unusual. Same as specific boards on 56/57s are allocated them to do with college loadings.
The 24 is undoubtedly the strongest of the 3, the 22 is more of an express into Durham going direct from Thornley to Sherburn though. I don't have enough experience of the network out that way to say whether they're performing massively well or poorly and I suspect a lot of the people posting don't either. There's very much a GNE biased view coming across for obvious reasons,, obviously the network has been cut back but services have to be profitable to be able to run and therefore once you get a profitable network you can add to it, rather than constantly cutting like Sunderland has seen.
