What was the fastest steam locomotive?
LNER Class A4 4468 Mallard
Duddington, then aged61, climbed into the cab, turned his cap around (as had George Formby in the contemporary film No Limit), and drove Mallard into the history books. He had 27years on the footplate, and had once driven the Scarborough Flyer for 144miles at over 74mph (average speed), considered at the time to be the highest speed ever maintained by steam in the UK.
