EMD G18

The EMD G18 is an export locomotive introduced by GM-EMD in the late 1960s. Standard EMD suffixes after the G18 designation show whether the customer bought traction motors for narrow gauge (U) or broad gauge (W) rails, an L marks a lightweight frame and a 6 marks A1A-A1A trucks. The related EMD GA18 is a G18 designed as an extremely light locomotive with freight car trucks driven by a cardan shaft, like its predecessor the GA8, and a further variation is the G18B. They are powered by an EMD 8-645E prime mover rated at 1100 bhp and 1000 hp for traction and were built with A1A-A1A or B-B trucks. Buyers included Chile, Indonesia, Iran, Israel, Peru, Saudi Arabia, South Africa and Spain, and Algeria bought many G18B and G18M units as light freight and shunting power from 1977.
