What's the current line speed between Royston and Cambridge (and beyond).
I remember a major track improvement project about nine years ago which
clipped an astonishing [sarcasm] one and a half minutes from the time to
London, through South Cambs. But the trains don't feel particularly fast.
80mph perhaps...

90 mph between Hitchin and Cambridge, but with quite a few local
restrictions to lower permitted speeds.
