The Alco S-6 (specification DL 430) was a
diesel-electricswitcher locomotive constructed by
ALCO of
Schenectady, New York; a total of 126 locomotives were built between May 1955 and December 1960. The S-6 was an improved version of the earlier
S-5.
Design
Visually indistinguishable from the S-5, the S-6 used an ALCO 251A or 251B prime mover rated at 900 horsepower (670 kW). The locomotive rode on two-axle
AARtrucks, giving a
B-B wheel arrangement. ALCO produced a
cow-calf variant for the
Oliver Iron Mining Company designated SB-8/SSB-9, two sets were produced of this version.[3]
