Baltimore & Ohio No. 50 - EMC 1800 HP B-B Diesel Locomotive
All were the mechanical ancestors to EMD's successful E-units, with identical pairs of 900 hp Winton 201-A Diesel engines, although they ran on AAR type B two-axle trucks instead of the A1A trucks of E-units. When delivered, the units were fitted with shrouding around their trucks, but this did not last long.
The boxy carbodies of all but the Zephyrs were the work of GE's Erie, Pennsylvania works, EMD having not yet developed the ability to produce their own bodywork. Like most boxcabs, they had control cabs at both ends, a feature that would only rarely be repeated in future North American locomotives, although it would become common elsewhere.
Baltimore & Ohio 50
Baltimore and Ohio Railroad #50 was fundamentally identical to EMC 1800 hp B-B demonstrators 511 and 512 when delivered. In this form, it hauled the first Diesel-powered Royal Blue until the introduction of the EA/EB units in 1937.
Following that, it had a semi-streamlined "shovel nose" applied to one end, and transferred to the B&O-owned Chicago and Alton Railroad to haul the Abraham Lincoln. When the Alton left B&O control in the merger that created the Gulf, Mobile and Ohio Railroad, #50 entered the GM&O roster as #1200. After World War II, the shovel-nose treatment was removed, restoring the unit to its prior boxcab appearance. The locomotive was placed into local freight service until it was retired, upon which it was donated to the Museum of Transportation, St. Louis, Missouri, where it remains.
