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 160 km/h (99 mph).[2] 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.
