My Lords, I promise that I will be quick. This amendment concerns the need to keep the west coast main line trains running into Euston while HS2 is constructed. When the Minister kindly met me last week, I showed him a cross-section drawing that I received some time ago from HS2 which described building what most people call a bird-cage—it is a hell of a big bird-cage; it is several train storeys high—near Park Village East. It shows how HS2 trains have grade separation, but it is all underneath three or four tracks of the west coast main line. I cannot see how you can build this bird-cage underground and keep the trains running on top. I have not had a sensible answer from anyone as to how it will be done. Perhaps the bird-cage is being redesigned; perhaps the tracks will be moved over, if that is possible; but it is important that the Minister can confirm that the west coast main line trains will keep operating during construction, because the poor old commuters and long-distance passengers will not be very pleased if it is closed for six months.
I have not received any later drawings of that cross-section. Perhaps it has changed but, under the version I had, I should think that you would have to close Euston for about a year. I hope that that is not the case, and I am sure that HS2 is coming up with alternative designs, but somehow those four tracks going into Euston must be kept operational—except for the odd weekend or night. I beg to move.
