The Tories have an undisputable history of hostility towards the railways. Macmillan gave us Marples who in turn gave us Beeching, and Major forced privatisation on us. Thatcher hated railways. Nobody who cares about this country's railways can ever vote Conservative with a clear conscience. As for this coalition, the best we can do is sit it out and hope that it falls apart after a year or two before any real damage is done.
Not strictly true. In fact the Labour party implemented the Beeching cuts, despite trying to get elected on a ticket not to. Indeed, after the 1955 rail strike, costs on the railways rose dramatically, not just as a result of the modernisation plan but union pay demands.
New Labour put in Network rail as a political decision, mainly as they party was run off Tony Blair's sofa. The biggest threat the the railways currently is their unsustainable cost (with NR being a big part of that) - and yes I agree the Tory privatisation was botched.
If you look what we got under the Tories: ECML electrification (admittedly done on the cheap), quite a few tram schemes, T&W metro, quite a bit of electrification and resignalling. On the flip side it was run on the cheap, the Woodhead line closed and the S&C was threatened with closure.
Always makes me laugh about is how ideological people get over political parties. The simple answer is it doesn't automatically follow that the railways are better off under one political party or another, it depends who is in those political parties, good management of the railways, the structure, and who is prepared to promote them.
Take New Labour for example: Alistair Darling and Stephen Byres had an almost complete disdain for them, and during the white paper they even asked if they were outmoded and should be closed. At the opening of the NET tram in Nottingham, Darling was heard to say under his breath 'let's hope this is the last of these ridiculous, expensive schemes' - and consequently pulled funding for schemes all over the country (apart from his own area). It wasn't until Adonis (and perhaps Prescott to an extent) that anyone in that party paid any attention to them. Most of the money always went on touchy feely stuff politicians think people care about, and where money has been spent, its mostly been wasted, mainly because of politics.
The only reason why some people think the Labour party are for the railways is the brainwashing from certain unions to vote Labour. While there are people who are in the Tory party, like John Redwood and Margaret Thatcher that are not all that keen on them, there are equally people that are: Steven Norris, Michael Portillio, George Young.
