I think it's fair to say that British governments of all colours have done the railways a massive dis-service, and that this goes back way before Beeching. The history of how the UK's railways got into this mess is a long and depressing onem and privatisation (and the current government's inability to fix it after 12 years) is only the latest chapter in a tale of interference, mis-management, and cuts. The system under which rail was common carrier worked well when there was no real road competition, but as government set all freight rates, rail couldn't adjust to compete, or recover their true costs.
@leswell - yes there is some good news from the rail industry. The issue at hand is really why it costs so much more to run than it did under state control, despite increasing fares and ridership, and whether the system is capable of ever handling the even larger passenger and freight numbers that would be required if oil dependency, climate change and congestion are to be addressed. At the moment it looks as if more capacity and greater ridership at lower fares would almost bankrupt the country (I exaggerate). The rest of the world seems to be capable of running a well used, intensive rail network at reasonable fares and recover much of it's costs (most true high speed rail - Eurostar excepted - seems to be at least marginally profitable), but the UK's insane organisational structure seems to dictate that profits are made and subsidies spiral out of control, without any real mechanism for the kind of investment in the future that is required.
Note also that the major projects such as Crossrail and High speed rail have not exactly sped ahead under privatisation. Rail re-openings almost completely stopped as well, as Railtrack's costs for doing the work doubled (or more). A lot more stations re-opened under the Tories than under the current Labour government.
Anyway, that felt more like 3c this time...
