It’s 8.16 on Tuesday morning and I’m actually writing this on a moving Elizabeth line train. Moving in the sense that we’ve just zipped from Paddington to Liverpool Street in 13 minutes – which if nothing else will be a boon for City commuters from west of London. Moving also in the sense that I’ve been writing about the project formerly known as Crossrail, first in optimism but later in frustration and rage, since its then chairman Terry Morgan gave me a personal tour of the Bond Street diggings back in June 2013.
