I must disclaim, I have no real interest in trains, but this is my second nerdy train post on the blog in a year!?
With all this talk of a new HS3 line I thought I’d compare reported operating speeds against average speeds across some of the better known lines. The results are in:
I tried to keep the distances similar when calculating average speeds from stations, but didn’t do too well. The average speed is the length of track from Station A to B divided by timetabled route length.
So it would appear the proposed HS2 will operate at speeds of up to 225mph (25mph faster than the Shinkansen) but still be 76mph slower on average.
