Maine Central EMD SW7 & SW9

The Maine Central EMPD SW7s were equiped with road-style MU and were painted in road colors, they were not intended for yard work. They entered service at Waterville in September 1950, breaking in on mainline locals, before moving to Bartlett within a month. Joined by SW9 334 eleven months later, the foursome took over local and helper operations on the Mountain, replacing Ten-wheelers on Mixed 377/378 to Beecher Falls, Mikados in helper service and working locals to Rigby and Gilman "in their spare time". When SW9 335 arrived in January 1954, the last 2-8-2 in standby helper duty was shipped to Waterville, totally dieselising the Mountain Sub. The local schedule kept the handsome switchers busy: Bartlett local RZ-2 departed Rigby 9am Monday, Wednesday and Friday, returning to Rigby 8am the following day using a single SW. A pair would be called about 3 am to help RY-2,

Pine green with gold band. In the summer of 1984 they were renumbered to MEC 933 and MEC934 in order to avoid conflict with Boston & Maine's former Conrail GP40-2s, and then became Springfield Terminal 1432 and 1433.
