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 shops in 1935.[1] The Lord Baltimore was built under the direction of the road's Master Mechanic George Emerson, and was said to have been inspired by the English locomotive King George, 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 the typical operating pressures were more commonly 250psi. 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, DC. Later on that year it was sent to the B&O-owned Chicago and Alton Railroad. It returned to the B&O in 1942 and after work in the B&O's shops it was renumbered to #5340 and assigned to service between Washington, DC and Cumberland, Maryland. Shortly afterward, it was withdrawn from service and stored at the railroad's shops in Baltimore, Maryland. In 1949, it was scrapped.
