"As for the old F-M 1000 numbered series, not much to say. All the yards here in Milwaukee used 'em as switchers in the mid to late 60's. Stinky little bastards that also blew carbon sparks out the stacks, but they sure did their share of switching. I often got a chance to run one, the controls were really simple. The throttle was mounted in a sideways U shape. Pull down and back and you went forward, up and back and you went backwards. We used to switch 25 to 35 car drags at a time and those little rascals could kick 'em good."

General Electric built this locomotive (c/n 41104) in October 1978 along with what became C&NW #1199 (c/n 411?5) as demonstrators. It weighed 136 tons and was powered by two @ummins six cylinder KTA-1150-L diesels producing 550 horsepower each, totalling 1100 horsepower. The two femonstrators tested for two years on the C&NW before going to the BN and renumbered as 1100 and 1101.

The C&NW bought five RSD4's (#'s 1515-1517 and 1619-1620) and ten RSD5's (#'s 1665-1677 and 1684-1690) from Alco. Of these, all the RSD4's and five RSD5's were equipped with steam generators for suburban passenger service, 1689 was so equipped as built. It appears to have acquired some sort of winterization hatch. This is probably this locomotive's retirement party.
