Sorry folks, but this seems like a lot of pointless bickering.
HS2 is being built.
Phase one will not be having any additional stations.
Preliminary work has already commenced at various points all along the proposed route.
There are work sites and compounds being established at various locations, nature reserves and wildlife refuges being created, utility services surveyed and preparations being made for their relocation, buildings being demolished etc, etc.
It could still be cancelled, with a few £billion already spent or committed written off in the process, but the first elements of the major construction work are due to commence in the not too distant future, which would then make cancellation of the project even more unlikely.
