I have some questions about this:
Additional services in the peak: I knew this was in the pipeline, but what are Northern going to use to run these trains? There is already DMU substitution on Airedale/Wharfedale in the morning peak (normally a growly Perkins 158). I always put this down to a lack of 333s - or is it in fact related to the power supply?
Shipley: When these routes were wired, Platform 3 at Shipley was extended to accommodate 91+Mk4 rake, and is used bi-di for that purpose for Bradford services (albeit less often than originally anticipated). The HST ex-Skipton calls at Shipley platform 1, which can only accommodate the leading power car + 4 coaches, which it presumably does under grandfather arrangements.
AFAIK the 225s don't have SDO. I was once set down at Finsbury Park following a signal failure and the guard opened one local door and everyone had to use that. Took hours to alight. Will this mean that the ECML service ex-Skipton won't be able to use Shipley platform 1?
Hope not. I use this to get to work sometimes, although must admit not many board at Shipley, most having crushed themselves onto the Northern service 6 mins earlier.
In GNER days, I could theoretically have brightened my commute with a cooked breakfast en route from Shipley to Leeds although I accept it would have been a bit of a rush...
