'''WDG-6G''' is a class of diesel-electric locomotive used by the [[Indian Railways]] for freight duty. The locomotive is a higher power variant of the [[Indian locomotive class WDG-4G|WDG-4G]] locomotive which was also designed by [[General Electric]]. The design platform is based on the [[GE Evolution Series]] and features a [[Four-stroke engine|4-stroke]] [[Engine configuration|16-cylinder]] fully [[Turbo-diesel|turbocharged engine]] which delivers around 6,000 [[horsepower]].<ref>{{cite news |title=Soon, “most powerful” WDG-6G diesel locomotive from GE to debut on Indian Railways tracks |url=https://www.financialexpress.com/infrastructure/railways/soon-most-powerful-wdg-6g-diesel-locomotive-from-ge-to-debut-on-indian-railways-tracks/1613276/ |access-date=1 July 2020 |publisher=financialexpress.com |date=20 June 2019 |archive-url=https://web.archive.org/web/20190629091504/https://www.financialexpress.com/infrastructure/railways/soon-most-powerful-wdg-6g-diesel-locomotive-from-ge-to-debut-on-indian-railways-tracks/1613276/ |archive-date=29 June 2019}}</ref>

==Import and manufacture==
Two units were produced by [[Wabtec]]'s plant in [[Pennsylvania]], United States, and delivered to India in 2019.<ref>https://www.thehindubusinessline.com/economy/logistics/railways-to-induct-countrys-most-powerful-diesel-locomotive-soon/article28066175.ece Railways to induct country's most powerful locomotive soon</ref> Initially, a few will be made in USA. Under the '[[Make in India]]' initiative of [[Government of India|Indian Government]], GE will manufacture all remaining units at its factory in [[Marhaura|Marhowra]], [[Bihar]]. GE has also built maintenance sheds at Roza in [[Uttar Pradesh|UP]] and [[Gandhidham]] in [[Gujarat]].

==Field trials==
The first two locomotives in the series, 69001 and 69002, were recently sent to [[South Central Railway zone|South Central Railways]]' Maula Ali (MLY) Diesel Locomotive Shed. The locos underwent Confirmatory Oscillograph Car Run (COCR) trials on the [[Vikarabad]] – Parli section of South Central Railway <ref>https://www.thehindu.com/news/cities/Hyderabad/first-ge-locomotive-to-be-tested-on-scr-tracks/article28068068.ece First GE locomotive to be tested on SCR tracks</ref> and were approved by [[Research Design and Standards Organisation]] for further field trials on the [[Dedicated Freight Corridor Corporation of India|Dedicated Freight Corridor]] by Roza Locomotive Shed.

==Improvements==

* Currently approved for test trials by RDSO at a maximum permissible speed of 65kmph. Trials are underway to increase the same.
* Current length of the loco is greater than any loco currently and hence facility of dual cab might be introduced<ref>http://www.indianrailways.gov.in/railwayboard/uploads/directorate/civil_engg/Sanction_Letters/2020_02_11%20Improvement%20of%20BG%20WDG6G%20class%20Diesel%20Electric%20Loco%20axle%20load%2023ton_2019-CEDO-SR-30(2)_RDSO.pdf Improvements of the WDG-6G class of Locomotive suggested by RDSO</ref>
