Indian locomotive class WAP-5

The WAP-5 is an Indian Railways class of electric locomotives for passenger trains. The first ten were imported from Adtranz in Switzerland in 1995, and Chittaranjan Locomotive Works in India built the later units. The locomotive has regenerative braking, flexible gear coupling and wheel-mounted disc brakes, with 160 kilonewton regenerative brakes, automatic train air brakes and a charged spring parking brake. On 3 July 2014 a WAP-5 set an Indian rail speed record by hauling a passenger train from Delhi to Agra at 160 kilometres per hour, covering the 200 kilometre run in about 90 minutes. A WAP-5A of 2015 was geared for trials at up to 200 kilometres per hour, and from 2018 an enhanced output of 4,500 kilowatts became the standard specification. Some units feed train power from the pantograph through head on generation, and asymmetric push-pull versions were built from 2020 for Tejas Express and Amrit Bharat Express services.
