Western Maryland Railway (WM) 75 & 76   

Delivered by General Electric in August 1943, units 75 and 76 were the Western Maryland Railway’s only GE 44-ton switchers. Built to work the road's extensive tidewater terminal facilities around Baltimore, they were assigned primarily to the sprawling yards, pier trackage, and car floats at Port Covington, as well as tight street-running switching around the Hillen Street terminal.   

Powered by a pair of Caterpillar D17000 diesel engines, their compact center-cab profile and lightweight footprint made them ideal for navigating the sharp curvature and weight-restricted trackage of dockside industrial spurs. Cloaked in WM’s clean black switcher livery accented with classic block lettering and diagonal safety stripes along the pilots, the duo shuffled freight along the harbor for over two decades until increasing car weights made the 380-hp switchers obsolete. Both were retired and sold off together in September 1964, with No. 75 later preserved at the Southern Michigan Railroad Society.
