Alco RSD-12

The ALCO RSD-12 was one of the diesel-electric locomotive of the road switcher type rated at 1,800 horsepower (1.34 MW), that rode on three-axle trucks, having a C-C wheel arrangement. 
171 locomotives were produced —Used in much the same manner as its four-axle counterpart, the ALCO RS-11, though the six-motor design allowed better tractive effort at lower speeds. 
Four examples survive today. NKP 329 is preserved as a museum display in Bellevue, OH. OERM 2954 (ex-SP 2954) and 2958 (ex-SP 2958) are preserved at OERM in Perris, California. Derelict LS&I 1804 rests in a shipyard in Escanaba, MI.
