EMD GA18

The EMD GA18 was an export locomotive built by GM-EMD in 1969. It was a derivative of the EMD G18 and was designed as an extremely light locomotive with low axle loading, using freight car trucks driven by cardan shafts and two traction motors attached to the underframe, and it was the successor to the EMD GA8. It was powered by an EMD 8-645E prime mover rated at 1100 bhp and 1000 hp for traction. Only seven units were built: one for Chile's Ferrocarril de Antofagasta a Bolivia, five for the Taiwan Railway Administration and one for Nchanga Consolidated Copper in Zambia. The Taiwanese units, named the S400 series, were equipped with a special cab signal display and track sorting devices for the Qidu hump yard and later pulled commuter trains. All have been scrapped except S405, which has been preserved.
