The EMD SW1 is a 600-horsepower (450 kW) diesel-electric switcher locomotive built by General Motors Electro-Motive Division between December 1938 and November 1953. Final assembly took place at EMD's plant in La Grange, Illinois. The SW1 used an EMD 567, V6 engine, which generated 600 hp (450 kW). 661 locomotives of this design were built, even though diesel switcher production was suspended between 1942 and 1945 by the War Production Board. The SW1 has a singular look with its sandbox in front of its radiator .
The SW1 in Z
The SW1 is made solely of thin-etched nickel-silver and brass castings. It uses a coreless 8 mm motor, with a two stage reducer: the 1st stage with belt, and the 2nd stage with worm and wheels on the two central axles. The two central axles are rigid, and the two front axles are on a pony truck. 6 wheels take electricity.
The truck faces are rigid and do not turn, but with the small length of this model, it is not very visible.
The model comes with body mounted "GH" couplers. It also features LED direction-controlled lighting.
They are available for DC power OR for DCC (with Z2 decoder).
Minimum radius : 195 mm (the "small" MTL track radius)
