Blackpool did not want people to have to change trains at Preston from Liverpool, under your proposal passengers would also have to change trains from Manchester at Preston. Would Blackpool be in favour of this or would it object? It would only have a direct service from York to Blackpool North. Could Preston cope with so many terminating trains and passengers changing from EMU to DMU ?
A number of Class 319's are currently at Wolverton, but not all will be needed in traffic until a few months after they should have been. Are Northern paying to lease the trains ? or paying for storage costs ? or does Porterbrook pick up the cost ?
All of the above are Network Rails problems due to late delivery of upgrades so does it pick up the costs or pay compensation ?
The risk will lie with DfT.
They may even have told NR to prioritise GW over NW, as it's a higher profile project.
Arriva will get a reduced financial target if necessary.
The 319s are probably on Porterbrook's books until they are fully modified for Northern's use.
They were not due in service until Dec 2017 anyway.
I shouldn't think anybody is thinking of hiring loco-hauled 442s.
Scotrail DMU cascades are also going to be late because of EGIP wiring delays.
I guess we should just be grateful that the Ordsall Chord is on schedule.
I would guess the Airport-Blackpool will run through whatever happens.
The Hazel Grove and Victoria services might be truncated at Preston, but we don't know the wider impact of the electrification delays.
