I guess when you look at the rolling stock situation, East Coast are already looking at more rolling stock so they can extend hourly to York. I would be good if these are all electric. Options they have looked at so far are.
1. Breaking up an mk4 set, so they have a series of shorter ones for less well used services (coupled with spare coaches) Not sure what they have spare to be honest but it would mean 9 coach for London - Edinburgh and maybe 7 coach for London - York.
2. Obtaining another HST.
Whatever they don't have enough stock for all the asparations. I think this is in order of current preference.
1. Make the x08 London - York path hourly
2. Extend all Newcastle terminators to Edinburgh
3. Extend some York terminators to Newcastle
4. More services to Bradford / Skipton
I think they will need 1 new set for option 1, 2 new sets for 2 (3 in total)
Investigations have also taken place for the 2016 timetable of something like this.
1. London, Newcastle, Edinburgh
2. London, Peterborough, Newark, Doncaster, York, Darlington, Durham, Newcastle, Alnmouth, Berwick-upon-Tweed, Edinburgh
3. London, Stevenage, Peterborough, Grantham, Newark, Reford, Doncaster, York, Northallerton, Darlington, Durham, Newcastle
4. London, Peterborough, Doncaster, Wakefield Westgate, Leeds
5. London, Stevenage, Grantham, Doncaster, Wakefield Westgate, Leeds
I suspect that the stopping patterns will be debated a lot. North of newcastle will always be a hard demand to satisfy. I don't know if hourly fast London - Edinburgh has demand but maybe in 3 years time it may do.
As I have said on other threads I would like to see open access operators stop at some of the smaller stations. Would HT doing London, Peterborough, Grantham, Newark, Retford, Doncaster onwards to Hull be a bad thing. Well yes if you want to get from London - Hull as quickly as possible. But the Grand Central could stop at other stations and still make it to York on its existing path.
