Diesel Locomotive Works
The Diesel Locomotive Works (DLW) in Varanasi, India, is a production unit of Indian Railways. DLW stopped manufacturing Diesel locomotives in March 2019 as IR is moving towards 100% electrification of its rail network. Currently DLW produces only electric locomotives WAP-7(Passenger) & WAG-9HC(Freight). It was the largest diesel-electric locomotive manufacturer in India.

Founded in 1961, the DLW rolled out its first locomotive three years later, on 3 January 1964. It manufactures locomotives which are variants based on the original ALCO designs dating to 1960s and the GM EMD designs of the 1990s.[2] DLW has an annual production capacity of 250 locomotives[3] and plans to increase it to 275 based on the current demand.[4][5] Since inception, DLW has manufactured a total of 8099 various types of locomotives(figures as of 31 January 2018). DLW manufactured 334 diesel-electric locomotives during financial year 2016–17, which is the highest ever loco production by any loco manufacturing unit in India and bagged the "Best Production Unit Shield" for the second successive year.
In AUGUST 2019, DLW developed the India's first bi-mode locomotive, the WDAP-5.
Locomotives produced at DLW
DLW locomotives have power outputs ranging from 2,600 horsepower (1,900 kW) to 5,500 horsepower (4,100 kW). Currently DLW is producing WAP 7 and WAG 9 for Indian Railways. Some of its EMD locomotive products are WDP-4D, WDG-4D, WDG-5 and others as of June 2015.DLW Stopped Production of WDG4D and WDP4D in March 2019.DLW recently started producing HEP capable WAP-7 high horsepower Electric Locomotives and its series starting from 37*** and WDM-2G genset locomotives. Recently, it has been allotted to Santragachi & Tughlakabad Loco Shed.
The designation of the locomotives follows the Nomenclature of Indian Railways. Prototypes and individual vehicles are not listed.
