reteps if it's the one I am thinking of then the tunnel was already there, it was part of the closed Penrith to ****ermouth freight line. It was covered in an episode of "Walking Britains Lost Railways" with Rob Bell.
This is what is sorely lacking in the UK, joined up thinking. They are already excavating for HS2, so bury the lines. You need cooling, so run the North<>South water transfer pipework alongside to cool it. Three projects in one.
Unfortunately it's the same old story in the UK, the kind of thinking where the council will resurface your road then the water board will come and dig it up two weeks later to lay new pipes.
