Equipment Information

Southern Pacific 1518 is the first SD-series (Special Duty) “road switcher” freight locomotive ever built. It was constructed at the EMD plant in LaGrange as prototype, or demonstrator, number 990 and was later sold to the SP. It is the forerunner of some 17,000 SD-series locomotives built between 1948 and the present.

COMPARE ME WITH: Chicago & North Western 1518, the first GP-series “road switcher” built by EMD. SP 1518 was closely based on the GP design but the SD-series was designed with six powered axles instead of four on the GP-series.
