'Indian Railways has created history by first-ever conversion of a locomotive from diesel to electric traction with almost double the power with indigenous technology under Make in India,' a senior Railway Ministry official told IANS.
'Indian Railways has created history by first-ever conversion of a locomotive from diesel to electric traction with almost double the power with indigenous technology under Make in India,' a senior Railway Ministry official told IANS.
He said the new electric locomotive entered into service with Northern Railway on December 3.
The official claimed that the DLW officials, for the first time in the world, have converted an engine from diesel traction to electric traction.
Explaining the rationale, the official said they had planned to discontinue mid-life rehabilitation of diesel locomotives and convert them to electric traction and gainfully utilise them for their maximum service life.
'Midlife rehabilitation of diesel locomotives costs around Rs 5 to 6 crore beyond 18 years. But only 50 per cent of this expenditure has been used for conversion to electric traction,' he said.
'A WDG3-class diesel locomotive which was due for a mid-life rehabilitation has been converted to electric and the new indigenous electric locomotive delivers 5,000 horsepower which is 92 per cent more than the 2,600 horsepower of the original version of the locomotive,' he added.
The official pointed out that work on the ambitious project began on December 22, 2017 and the refurbished locomotive was dispatched on February 28.
He said it took only 69 days from 'concept to execution of the conversion of the diesel locomotive to electric'. And after its mandatory trials, the locomotive was launched from Varanasi to Ludhiana on December 3 and travelled at a maximum permissible speed of 75 kmph.
The official said the project is a step forward towards saving of traction energy cost which in turn will reduce railways' fuel bill and also reduce carbon emissions, besides introducing new age technology.

The Diesel Locomotive Works (DLW) in Varanasi, India, is a production unit owned by Indian Railways, that manufactures diesel-electric locomotives and its spare parts. It is the largest diesel-electric locomotive manufacturer in India. It is located on DLW to BHU road of the metropolitan city of Varanasi.
Company[edit]
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 produced total 8099 locomotives (up to 31 January 2018) of various types. DLW now manufactures'More than one locomotive a day'. DLW manufactured 334 diesel-electric locomotives in last 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.[6]
Products[edit]
DLW locomotives have power outputs ranging from 2,600 horsepower (1,900 kW) to 5,500 horsepower (4,100 kW). Currently DLW is producing EMD GT46MAC and EMD GT46PAC locomotives under license from Electro-Motive Diesels (formerly GM-EMD) for Indian Railways. Some of its EMD locomotive products are WDP4, WDP4D, WDG4D, WDG5 and others as of June 2015. DLW recently started producing HEP capable WAP-7 high horsepower Electric Locomotives. Recently, it has been allotted to Santragachi & Tughlakabad Loco Shed.[5] It will also produce WDG4G (ES43ACmi, Customized for IR) Locomotives From General-Electric Transportation.
Market[edit]
Besides the Indian Railways, it regularly exports diesel-electric locomotives[5] and has supplied locomotives to other countries such as Sri Lanka, Nepal, Bangladesh, Mali, Senegal,[7]Sudan[8]Tanzania, Angola, and Vietnam and also to a few users within India, such as ports, large power and steel plants and private railways.[9][10]
Ancillary[edit]
In July 2006, DLW outsourced manufacture of some passenger and freight locomotives to Parel Workshop, Central Railway, Mumbai.[11]

The class WDM-2 is Indian Railways' workhorse diesel-electric locomotive. The first units were imported fully built from the American Locomotive Company (Alco) in 1962. Since 1964, it has been manufactured in India by the Diesel Locomotive Works (DLW), Varanasi. The model name stands for broad gauge (W), diesel (D), mixed traffic (M) engine. The WDM-2 is the most common diesel locomotive of Indian Railways.
The WDM-2A is a variant of the original WDM-2. These units have been retro-fitted with air brakes, in addition to the original vacuum brakes. The WDM-2B is a more recent locomotive, built with air brakes as original equipment. The WDM-2 locos have a maximum speed of 120 km/h (75 mph),[1] restricted to 100 km/h (62 mph) when run long hood forward - the gear ratio is 65:18.

History[edit]
In the early 1960s Indian Railways began conversion of its mainline from steam to diesel locomotives. For this conversion General Motors Electro-Motive Division (EMD) and the American Locomotive Company (ALCo) were asked to submit designs for new diesel locomotives. Each company submitted prototypes. Indian Railways designated these prototypes the WDM-4 class and the WDM-2 class respectively. Technologically the General Motors WDM-4 was superior to ALCO's WDM-2, but Indian Railways required a transfer of technology agreement that would allow these locomotives to be manufactured in India. General Motors did not agree to the transfer of technology agreement so the ALCo prototype was selected for production. The first few prototype WDM-2 were imported. After Diesel Locomotive Works (DLW) completed construction of its factory in Varanasi, production of the locomotives began in India. The first 12 locos were built using kits imported from ALCo in the United States. After that DLW started manufacturing the WDM-2 locomotives from their own components. Since then over 2,800 locomotives have been manufactured and the WDM-2 has become the most popular locomotive in India.
However, even before the arrival of WDM-2 another type of diesel locomotive was imported from ALCo beginning in 1957. This locomotive was classified as WDM-1.
Later a number of modifications were made and a few subclasses were created. This includes WDM-2A, WDM-2B and WDM-3A (formerly WDM-2C). Now a few WDM-2 locos are being rebuilt by Diesel Loco Modernization Works (DLMW) Patiala, Punjab. These are fitted with Daulat Ram DBR's
The WDM-2 is the diesel workhorse of the Indian Railways, being very reliable and rugged.

Sri Lanka[edit]
Eight WDM-2 locomotives were purchased by Sri Lanka Railways, the state run railroad operator in Sri Lanka in 1996. They were the longest and most powerful locomotives owned by Sri Lanka Railways at that time. They were allocated the M8 class.[3] However some modifications to the appearance were done by SLR.[4]
