what's the real (as opposed to ideal) alternative?
The entirely real alternative is to build the tunnel a bit longer, say 4.5 miles instead of a niggardly 2.9 miles.This can't be claimed to be technically impossible as we built a rail tunnel of 4.5 miles under the Severn 150 years ago.
Nor can it be claimed to be too expensive as we are going to build a tunnel for HS2 under the Chilterns which will be 10 miles long.
Small wonder Scotland wants to break loose.
