ALCo RS-1 on the Arkansas & Missouri Railroad


The Arkansas & Missouri is a Class III railroad established in 1986, operating a 150 mile (242 km) route which offers freight and passenger excursion trains, website.

The ALCo RS-1 was a 4-axle B-B type diesel-electric locomotive built by Alco-General Electric between 1941 and 1953 and the American Locomotive Company from 1953 to 1960, with a total production of 469. This model had the distinction of having the longest production run of any diesel locomotive for the North American market. The carbody configuration of the RS-1 pioneered the road switcher type of diesel locomotive. Most locomotives built since have followed this basic design.
The first thirteen production locomotives were requisitioned by the US Army, the five railroads affected had to wait while replacements were manufactured. The requisitioned RS-1s were remanufactured by ALCo into six axle RSD-1s for use on the Trans Iranian Railroad to supply the Soviet Union during WW2.
