The ALCO Century 636 was the most powerful single-engine diesel locomotive constructed by ALCO. The locomotive had a C-C wheel arrangement and 3600 horsepower (2.7 MW). The locomotive rested on a pair of trucks of all-new design, known as the Hi-Ad, standing for 'high adhesion'. Visually, it is almost identical to the Century 630.
Production
Besides the 34 C636s built in 1967 and 1968 for American railroads, 17 C636s and 37 M636 were built for the Australian company Mount Newman Mining in 1968. Also entering service in 1968 were 39 C/M636s for Hamersley Iron. Robe River was the other Pilbara-based company to acquire units of the C/M636 type, with 12 entering service in 1971.
