I wonder, is it possible that at least some of the difference in subsidy levels is down to the fact the Northern run an ageing fleet of stock and keeping them running is cutting deeply into profits? From a passenger point of view there seems to be little wriggle room for Northern when a unit fails, so I imagine that keeping them in service is a constant headache for them. Is this even an argument for considering investing in new stock rather than hand-me-downs for the next franchise?
As for some of their routes, yes a bit like ScotRail or Arriva Wales they serve some far flung locations with sparse populations but is this really any justification for another Beeching style cull? Take the Esk Valley route to Whitby for example. OK, the bus is probably going to be a quicker run to Middlesbrough than the train. However one has to ask what is Whitby's biggest draw? Well it's obviously tourism, so would we really expect all people travelling by public transport to ram themselves onto the local bus services (currently 1ph from Middlesbrough by the X93 (although there are other longer services) or 2ph from Scarborough by the 93/X93, or the semi frequent Coastliner from Leeds & York), luggage an all? So it may be a loss maker at the moment, but if performs a valuable service for Whitby & the surrounding villages. Perhaps it was better connected to services at Middlesbrough, or perhaps there was even a through service from York it might attract even more patronage. Currently the connection time from the ex-Manchester Airport TPE gives only around 7 or 8 minutes connection which buggers up the job if your service is running late.
Northern have plenty of profit-earning routes, crammed to the hilt with passengers heading for places like Leeds, Manchester, Liverpool etc so there must be some way of balancing the profitable routes with the less so. And other major centres given better connections can easily be turned into profitable routes, you only have to look at the number of traffic jams across the North of England to realise there's plenty of potential new custom there. But the sparely populated areas should not be dropped from the rail network, because our transport network should serve people & not shareholders. And if that means continued subsidies, or even heaven forbid some form of re-nationalisation, then so be it in my opinion.
