Bit torn on this one. It seems such a lot of money and disruption when the whole rail infrastructure needs to be improved. On the other hand I live in a town which will greatly benefit in terms of jobs and the local economy etc.
Surely it would be better to upgrade all our train lines to use them for freight. There are still lots of derelict goods yards that could be used for such a purpose, not to mention the chopping down of ancient woods etc.
