Indian locomotive class WAP-5

The Indian locomotive class WAP-5 is a class of electric locomotives used by Indian Railways. The first ten locomotives were imported from Adtranz in Switzerland in 1995; locomotives were later manufactured by Chittaranjan Locomotive Works in India. The locomotive has regenerative braking, flexible gear coupling, wheel-mounted disc brakes, and a potential for speed enhancement to 200 km/h (120 mph). Braking systems include 160 kN (36,000 lbf) regenerative brakes, disc brakes, automatic train air brakes and a charged spring parking brake. On 3 July 2014, a WAP-5 locomotive set an Indian rail speed record by hauling a passenger train between Delhi and Agra at 160 km/h (99 mph) during a trial run, completing the 200 km journey in about 90 minutes.
