The Indian locomotive class WDP-1 is a class of diesel-electric locomotive that was developed in 1995 by Banaras Locomotive Works (BLW) for Indian Railways. The model name stands for 5 ft 6 in gauge railway, broad gauge (W), Diesel (D), Passenger traffic (P) engine, 1st generation (1). They entered service in 1995. A total of 69 WDP-1 units were built at Banaras Locomotive Works (BLW), Varanasi between 1995 and 1999. The WDP-1 served both passenger and freight trains for over 25 years. Despite the introduction of more modern types of locomotives like Indian locomotive class WDG-4, WDG-4 and electrification, a significant number are still in use, both in mainline and departmental duties. As of April 2022, 57 locomotives still retain "operational status" on the mainline.

History

The WDP-1 is a lower powered version of the Indian locomotive class WDM-2, WDM-2. These locos have a 2300 hp powerpack, . The engine is a converted version of the Alco 251C model with a 12-cylinder engine and low overall weight with a max. speed of 140 km/h, Bo-Bo fabricated bogies loosely based on the Flexicoil models. They are still in service and are homed either at TKD & BZA to haul short commuter trains and shunting around the area. They look just like all other ALCOs and are easily identified by the laterally “sculpted” and baldie grille-less short hood. WDP1M is a rebuilt version with better powerpack and better cooling via a modified radiator. The biggest change is in the suspension. Rubber springs have been provided instead of coil springs, along with other changes to the suspension and axle components. The scrapping of these locomotives has begun.
