They can be used in service, yes, however using them on the X21/22 is doing them no good at all. There are plenty of services within the North East that they are well suited for, just not the X21/22.
Probably more likely to be 7472 than 7416?
7416 is more likely to move elsewhere because 7472 is likely to stay at ashington or be withdrawn
