In June 1987, I saw this EMD built SW8 800 hp switcher #C989 switching at the
Coors's Golden brewery. It was built in 1952 and is still in service with Coors.
SW8 switchers were built between 1950 & 1954 and this loco was ex-Rock
Island 832 (built in Nov 1952, serial number 16630) and it entered Coors
service in February 1981
