Two versions were built, with the same RSD-7 model designation but different specifications and power ratings, although both used the ALCO 244 engine in V16 configuration. Specification DL-600, of which only two were built, developed 2,250 hp (1,678 kW; 2,281 PS) and used the 244G engine. The revised specification DL-600A, numbering 27 locomotives, was rated at 2,400 hp (1,790 kW; 2,433 PS) and used the 244H engine. The RSD-7 was superseded by the ALCO 251-engined ALCO RSD-15, which looks very similar. The RSD-7 was the last ALCO diesel built with a 244 engine.Both rode on a pair of three-axle trucks with all three axles on each truck powered; this is a C-C wheel arrangement. These trucks have an unequal axle spacing due to traction motor positioning; the outer two axles on each truck are closer together than the inner two. The RSD-7 used the GE 752 traction motor. The six-motor design allowed better tractive effort at lower speeds."@en }
