ABOUT THE RAILKING O SCALE SD-9 DIESEL LOCOMOTIVE

In the General Motors' Electro-Motive Division time line, 1954 holds significance for two important events. In that year, the manufacturer produced its 15,000th locomotive and introduced the 1,750-h.p. SD9. The road switcher was produced until 1959. Basically, an elongated — and, some might say, handsomer — version of EMD’s very popular GP9, the SD9 spread the same horsepower over two additional axles, resulting in a lower loading on each axle. This made the engine more suitable for use on light rail and in situations requiring power at low speeds, such as hump yard service.

The RailKing Scale model of the SD9 is built to 1/48th scale proportions and is thus somewhat larger than typical RailKing diesels. O gauge operators looking for scale proportioned locomotives will find durable, yet well detailed, RailKing Scale models to be an excellent alternative to more expensive O scale diesels.
