The GE C36-7 is a 6-axle diesel-electric locomotive built by GE Transportation Systems, GE do Brazil and A Goninan & Co between 1978 and 1989. It is an updated GE U36C with a 16-cylinder FDL engine. It is externally similar to the GE C30-7 but has larger air intakes under the radiators. The dynamic brakes grids of later units are located in a high box behind the cab.[1] C36-7s were constructed with either 3,600 or 3,750 hp.[2]
