5 Mk4s diagrammed a day, the new fleet would of been at least 10.But the new fleet would have seen off the IC225s, so the carriages would have been the same? I know 225s can’t go to Middlesbrough, but the Azumas that would have to cover for them if they went off lease - and now don’t have to - can.
Not that I believe Middlesbrough justifies 1tp2h.
1tp2h to Bradford Forster Square could really threaten Grand Central. Mind you, seeing as they seem the much more expensive train to Doncaster, York and Wakefield than LNER and Hull Trains, I’m not necessarily complaining.
They can only do extra Middlesbrough with additional Azuma if mk4 go.
