Thanks for that.
Do you know which services over the Pennines remain 68 hauled? Are they the ones listed in my earlier post, or is there some new variant planned?
Sadly I don’t remember myself as I don’t sign the traction, but the information should be available soon.
I strongly believe it will be the diagrams you’ve posted AFAIK, utilising three units on rotation, with a set swap on the first half of diagram B. Ie one unit stays in Scarborough overnight and is swapped at Ardwick mid-morning with a new set
