7701-19 due to start entering service later this coming week - Ashington drivers all need familiarisation. Obviously lots were also photographed without vinyls, so they will all need applied before entering service here.
There's 10+ spares isn't there, on paper anyway? Quite a few really, obviously ignoring reliability here. Believe they usually work on a 10% rule and that's well over.
Unless there's another 2 which Ashington haven't put out Blyth currently have 6 vehicles and Ashington only have 4 vehicles from the swap so who knows.
