Does HS2 pass the Butterfield test?
Despite my opposition to High Speed 2, I am quite a big fan of HS1, the line which runs from St Pancras to Ebbsfleet, Ashford and on to other towns in north and east Kent. I also think HS3 — a proposed line linking the cities of t’Northern Powerhouse — is a good idea. Why the inconsistency? Well, I believe HS1 and HS3 are significant innovations whereas HS2, though it costs far more and covers a much greater distance, is not. In fact I would argue, counterintuitively, that HS2’s greater length is precisely what makes high-speed rail less necessary: the cost of the longer journey means that most people do not make it very often.
