You are right though, Britain really ought to be much further ahead with railway infrastructure. It's a huge problem in Wales - an airport link recently opened between North and South Wales because by car it takes half a day and it's even longer by train. We'll see what the Wales Transport Strategy and regional committees come up with.
You can guarantee that when Britain does start to sort out it's act with high speed rail links, it will only be for select bits of England. Wales will be left off the map completely. Ad astra per aspera
I'm not sure I understand, do you mean that tunnelling teams failed to meet? If that is the case, you must have been misinformed back then: the information that may have been corrupted was that one of the tunnel boring machines was simply driven to the right of the tunnel axis before the end point and left there, because that was deemed cheaper than dismounting it & transporting the parts all the way back. *Lunatic*, n. One whose delusions are out of fashion.
