Speaking of locomotive surefootedness, I was immensely impressed, on a recent journey with the down "Ulsterman" from Euston, when "Royal Scot" 4-6-0 No. 46168, The Girl Guide, cleanly lifted a well-filled 15-coach train of 471 tons tare and 500 tons gross out of the terminus without the service of any banking engine.
