Derived from the EMD SD70MAC, it is powered by a 4,000 hp (3,000 kW) 16-cylinder EMD 710G3B prime mover. Thirteen were built by EMD as order #958647, and a further eight were exported in kit form and assembled in India. The class entered service in 1999. A Dedicated Passenger version of this locomotive, the WDP-4, has also been produced, with a Bo1-1Bo Wheel Configuration, which entered service in 2001.

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 remain the main diesel traction power of Indian Railways.
