Theres a reasonable chance that VTEC will hit the Open Access operations harder than previous operators of the ECML franchise have, or make it harder for new applications on their line.
GNER seem to have been too tied up with their parent companys troubles in later years.
NXEC had ambitions of their own to stifle potential Open Access paths (trying to move into the Harrogate market to stop potential bids for such a service).
East Coast seem to have been pretty modest, seemingly no commercial motive (hence the lax approach to bothering to check tickets I think the new franchise will surprise a few people whod got away without tickets...), not interesting in getting into fights for territory.
The new franchise is going to have additional resources to play with (compared to a fleet thats been pretty stagnant since privatisation, apart from an odd HST here and there) and therefore have the tools to compete on Wearside (faster service to Sunderland than Grand Central can offer), Teesside (actually serving Middlesbrough) and Bradford (again, faster than GC) and possibly Kirklees (actually serving Huddersfield).
So, that leaves GC as number one in smaller markets like Hartlepool, Brighouse and Halifax, as well as competing for cheap fares at York/ Doncaster etc with a TOC thatll see a significant increase in seating capacity (when the 800/801s arrive) and therefore more capacity to dump cheap tickets onto the market.
Theres probably a market for some of the GC services, but if they arent operated by the main ECML TOC then they may struggle at the bottom of the market - £25 tickets to London sound good to a passenger but youre going to have to pack a lot of them onto your three hundred seat 180s to have the same revenue as an 800 where most passengers are on standard/open tickets.
If VTEC get a bigger share of the ORCATS market for Sunderland/ Bradford/ Teesside to London and defend their share of the York/Doncaster to London market then GC are going to find things a lot tougher than they did against the softie East Coast. Would you be surprised if VTEC question the methodology of the ORCATS allocation at York/ Doncaster to try to secure a bigger slice of the cake for themselves?
Certainly I expect them to put up a robust defence against any further applications/ paths (whether thats GC running through Leeds, applications for services from London to Yorkshire via Manchester Victoria), whereas EC may have been meeker.
From the noises Ive heard, the new franchise seems less interested in competing to Hull possibly because theres no way of competing with them without clear duplication (other than going via Goole instead of Selby?), or because Hull Trains have got the market sown up pretty well.
(obviously theres a certain enthusiast hypocrisy about Open Access firstly the TOCs shouldnt be allowed to fight back against Open Access operators, though it was okay for the Open Access operator to set up in the first place line of argument, secondly the we shouldnt have a fragmented railway, things were better when everything was BR, but if operator specific tickets and confusing restrictions mean I can get to London for £25 then Im all for it line...)
