GM&O RS1 1122
Title:  GM&O RS1 1122
Description:  Gulf Mobile & Ohio Railroad RS1 1122 at Glenn Yard on the southwest side of Chicago, Illinois on February 14, 1965, photo by Chuck Zeiler. Built in January 1949 (c/n 76625) it was retired in September 1976. Note that the road number is painted on the headlight glass L&N style. The GM&O must have been pleased with a 1000 hp road switcher, because the RS2 was in production at the time this unit was built, offering 1500 hp in a similar configuration. The RS1 production ran from the first unit for the Rock Island in 1941 to the final units for the NdeM built in 1959-1960.

Title:  GM&O RS1 1122
Description:  Gulf Mobile & Ohio Railroad RS1 1122 at Glenn Yard on the southwest side of Chicago, Illinois on February 14, 1965, Kodachrome by Chuck Zeiler. The RS1 was powered by a 6-cylinder inline turborcharger McIntosh & Seymour Model 539 diesel prime mover producing 1000 horsepower. The GM&O purchased 24 RS1's (road #'s 1102-1117 and 1120-1127) and through merger with the Alton Railroad acquired another 10 (road #'s 50-59). The RS1 holds the record for the longest running production of a single model, first produced in 1939 at the request of the Rock Island, and concluding with an order for the NdeM in 1960.
