This SW locomotive was built in March 1937 by the Electro-Motive Corporation as Philadelphia Bethlehem & New England Railroad 206. From there, this 800 horsepower diesel went to the Steelton & Highspire (as SH 23), then to Maryland & Pennsylvania Railroad (as MPA 83) and then to Stewartstown Railroad (STRT 11). It is now, as seen there, owned by Allentown & Auburn Railroad, as their 206. (Topton, Pennsylvania – September 26, 2025). Photographed on railroad property with permission and full PPE.
