Some bits of it are already open to passenger trains - Oxford to Bicester Village and Bletchley to Bedford for instance. Other bits will be a bit more tricky - a radio telescope currently occupies a 3 mike stretch near Cambridge for instance.
My understanding is that Bicester Village itself stumped up some of the cash for this. Correct me if I am wrong. Incidentally, the line run by Chiltern Railways is owned by DB. Yep, you read that right, German State owned railways. It is possible to have nationalised railways in the EU, it's only our own Government which thinks that privatised railways which have to be bailed out are the way forward.
Re structural funding it makes much more sense to me for the UK to be assessing its own needs
I don't know how many years they have been taking about re-opening this railway line, so what stopped the Tories making plans in 2010? I gather that there is a short stretch which has been built on which is one of the stumbling blocks.I didn't know about the radio telescope, I thought it was housing now in the way of the old line.
