The Indian locomotive class WDM-2 is a class of diesel-electric locomotive that was developed in 1962 by American Locomotive Company (ALCO) for Indian Railways. The model name stands for broad gauge (W), Diesel (D), Mixed traffic (M) engine, 2nd generation (2). They entered service in 1962. A total of 2700+ WDM-2 was built at ALCO and Banaras Locomotive Works (BLW), Varanasi between 1962 and 1998, which made them the most numerous class of mainline diesel locomotive until its successor the WDM-3A.
The ALCO DL560C is a series of diesel-electric locomotive with AC electric transmission designed by the American Locomotive Company and produced under license by Banaras Locomotive Works (BLW) Varanasi, India for Indian Railways as their classes WDM-2, WDM-3A/2C, WDM-3D and WDG-3A for operation in India. The locomotive is fitted with a 16-cylinder ALCO 251 B,C diesel engine. In the early 1960s Indian Railways needed a reliable diesel workhorse to gradually replace its steam locomotive fleet. Equal numbers of ALCO's DL560C and EMD's G16 were chosen for trials. More locomotives of each of these were purchased for more trials. Indian Railways was keen on producing these locomotives in the country rather than depending on imports. EMD did not agree for a Transfer-of-Technology, while ALCO did. Thus ALCO DL560C was chosen for the job due to its easy maintenance, reliability and simple operation. And from then on vast numbers of this loco in different configurations have been produced and they still continue to dominate the diesel route of Indian Railways.
