Baltimore and Ohio No. 2 Lord Baltimore

The Baltimore and Ohio Railroad's sole class V-2 4-6-4 steam locomotive, No. 2 Lord Baltimore, was constructed by the railroad's own Mount Clare Shops in 1935.^[1] It was built under the direction of the road's master mechanic George Emerson, and said to have been inspired by the Great Western Railway locomotive 6000 King George V which had appeared at B&O's 1927 Fair of the Iron Horse.

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 Shortly afterward, it was withdrawn from service and stored at the railroad's shops in Baltimore, Maryland, and was scrapped in 1949.
