The US locos were maintaining their speeds for mile after mile, up hill and down hauling 1000 tons trains. keep to the Fen Causeway
Not quite. It is true that the LNER's Mallard might have briefly touched 125 mph on the way down Essendine bank, while a heavier Milwaukee Road test train maintained 120 mph for over five miles, with a possible maximum of 125 or 126 mph on a slight downgrade, but the best performances with steam Hiawathas were 30 miles or so at 100 mph but not exceeding 110 with at most nine car trains.
But I'm with DoDo in championing the Milwaukee Road as operator of the world's fastest steam engines. (And there's a lot about the Midwest Hiawatha line through Hampshire, Genoa, and Kirkland in my back yard that hasn't been properly investigated.) Stephen Karlson ATTITUDE is a nine letter word. BOATSPEED.
