DL 430) was a diesel-electric locomotive of the switcher type constructed by ALCO of Schenectady, New York; a total of 126 locomotives were built between May 1955 and December 1960. The S-6 was a development of the earlier S-5; instead of the 800 hp ALCO 251 engine on the previous locomotive, the S-6 used a 251A or 251B engine rated at 900 horsepower. The locomotive rode on two-axle AAR trucks, giving a B-B wheel arrangement. A cow-calf version was produced exclusively for Oliver Iron Mining Company, who bought two: this was the SB-8/SSB-9 (DL-441).
