Data from Edwin Alexander, Iron Horse (Bonanza Books, 1950).
This design's unusual look stems from its Anglo-American origins. On the one hand, the steel came from Britain (16 cents a pound), the boiler was straight, the stack tall, and the wheel arrangement classical for a British "goods" engine. On the other the high running board, full cab, and large headlight gave it a North American appearance. Alexander (Iron Horse, pl 47) quotes Locomotive Superintendent Richard Eaton's annual report for 1860 in which he reports that Scotia and Erin have "commenced work most satisfactorily." Later these coal burners used wood and were fitted with a spark -arresting balloon stack.
