The Legacy of U.S. Army 8669: A Historic RSD-1 Locomotive

The U.S. Army 8669, a remarkable RSD-1 locomotive, stands as a testament to the engineering prowess of the American Locomotive Company (ALCO). Crafted in 1945, this locomotive sets itself apart with its six axles, in contrast to the RS-1’s four. With a robust power output of 1,000 horsepower, the 8669 has been a force to reckon with.

After its tenure with the U.S. Army, the locomotive found its next mission with the U.S. Air Force at Eglin Air Force Base. By the end of 1978, the Tennessee Valley Railroad Museum (TVRM) became its proud custodian. As a seasoned diesel-electric locomotive, the 8669 has played a pivotal role in powering TVRM’s passenger trains, notably the Missionary Ridge Local and several extended excursion trains.

Currently, the 8669 is taking a well-deserved rest and is on display at Grand Junction. While it awaits essential electrical and mechanical repairs, visitors can marvel at this historic locomotive and appreciate its significant contributions to the world of rail.
