The locomotive was constructed with an experimental water tube firebox, and operated at 350 psi when more typical operating pressure was 250 psi. The 84-inch drive wheels were the biggest ever on B&O steam. It was constructed to haul a new lightweight train, the Royal Blue, between New York City and Washington, D.C. Later that year it was sent to the B&O-owned Chicago and Alton Railroad. It returned to the B&O in 1942 during World War 2 and, after work in the Baltimore and Ohio Railroad's shops, was renumbered to #5340 and assigned to service between Washington, D.C. and Cumberland, Maryland. Shortly afterward, it was withdrawn from service and stored at the railroad's shops in Baltimore, Maryland, and was scrapped in 1949.
