The Indian locomotive class WAP-5 is a class of electric locomotives used by Indian Railways. The first ten locomotives were imported from ABB in Switzerland in 1995 and later manufactured by Chittaranjan Locomotive Works in India. On 3 July 2014, a WAP-5 set an Indian speed record by hauling a train between Delhi and Agra at a speed of {{convert|160|km/h|abbr=on}}.{{cite news|title=200 km in 90 mins: Delhi-Agra high speed train sets new speed record |url=http://articles.economictimes.indiatimes.com/2014-07-03/news/51057656_1_speed-record-fastest-train-passenger-train|archive-url=https://web.archive.org/web/20140707064334/http://articles.economictimes.indiatimes.com/2014-07-03/news/51057656_1_speed-record-fastest-train-passenger-train|url-status=dead|archive-date=7 July 2014|access-date=10 July 2014|newspaper=The Economic Times|date=3 July 2014}} The locomotive has regenerative braking, flexible gear coupling, wheel-mounted disc brakes, and a potential for speed enhancement to {{convert|200|km/h|abbr=on}}. Braking systems include {{convert|160|kN|lbf|abbr=on}} regenerative brakes, disc brakes, automatic train air brakes and a charged spring parking brake.

In October 2015, a WAP-5A locomotive (no. 30086) was rolled-out with a gear ratio of 59:35:19 capable of speeds up to {{convert|200|km/h|abbr=on}} for trial runs. In March 2018, a WAP-5 locomotive (no. 30136) with an enhanced power output of {{Convert|4500|kW|hp}} was released which was later adopted as a standard based on successful trials. Some locomotives of this class are equipped with "Head On Generation" (HOG) in which electric power from the locomotive's pantograph is transferred to the coaches instead of "End Of Generation" where a power car equipped with diesel generator is provided at either end of the train rake to supply power.{{cite news|url=http://www.indianexpress.com/news/train-had-wap7-engine-black-box-may-reveal-cause/816265/0|title=Train had WAP-7 engine, 'black box' may reveal cause|newspaper=Indian Express|date=9 Aug 2010|access-date=25 Aug 2012}}{{cite web|url=http://www.clw.indianrailways.gov.in/view_section.jsp?lang=0&id=0,296,306,470|title=Recent Developments|publisher=Chittaranjan Locomotive Works|access-date=25 Aug 2012}}{{cite report|url=http://www.rdso.indianrailways.gov.in/works/uploads/File/Electrical(1).pdf|title=Development of Electric locomotive with Head On Generation (HOG) facility|publisher=Indian Railways|access-date=1 December 2023}} The first WAP-5 locomotive (no. 30140) with HOG was rolled by CLW in June 2018.{{Citation needed|date=March 2025}}

In October 2020, two WAP-5 locomotives (no. 35012 and 35013) were given an asymmetric body design with an aerodynamic profile for one cab and a blunt profile for another cab at the opposite end, which is intended to be semi-permanently coupled with a train in a push-pull configuration for Tejas Express services. The two locomotives have a power output of {{Convert|6000|hp|kW}} and will have a maximum speed of {{Convert|160|km/h|mph}}.{{cite news|title=New Aerodynamic 160 kmph WAP-5 Locomotives Flagged Off At CLW |url=https://www.railpost.in/new-aerodynamic-160-kmph-wap-5-locomotives-flagged-off-at-clw/|work=Railpost.in|date=2 October 2020|access-date=27 December 2020}} Two modified WAP-5 locomotives (35027 and 35028) are used to haul the Amrit Bharat Express in a similar push-pull configuration.{{cite news|last=Nigam|first=Saumya|date=27 December 2023|title=Amrit Bharat Express to launch with Push-Pull technology and other exciting features|url=https://www.indiatvnews.com/explainers/amrit-bharat-express-to-launch-with-push-pull-technology-and-other-exciting-features-details-2023-12-27-909203|access-date=28 December 2023|work=India TV|language=en}}{{cite news|date=30 October 2023|title=Vande Sadharan train: All you need to know; How it is different from Vande Bharat train?|url=https://www.businesstoday.in/latest/in-focus/story/vande-sadharan-train-all-you-need-to-know-how-it-is-different-from-vande-bharat-train-403792-2023-10-30|access-date=30 December 2023|work=Business Today|language=en}}
