136-588: The 21st century, used to be a dominant gauge at that time. After the introduction of YDM-1 locomotives by the North British Locomotive Company , Indian Railway considered more powerful ones and hence General Motors Electro-Motive Division (EMD) and the American Locomotive Company (ALCO) submitted designs of YDM-3 / YDM-5 ( 12-567C ) and YDM-4 respectively for new diesel locomotives. Each company supplied 30 locomotives in 1961. While
153-777: The YDM-3 was 13 tons lighter than the YDM-4, Indian Railways opted for the ALCO design because of the heavier axle load and technology agreement that would allow these locomotives to be manufactured in India. After Banaras Locomotive Works (BLW) completed construction of its factory in Varanasi, production of the class began in India. The initial 30 YDM-4 locomotives supplied by ALCO in 1961 were numbered between #6020 and #6049. Another batch of 8 locomotives soon followed and were numbered #6105 to #6112.
