WAP 5 is the name of a class of electric locomotive used by Indian Railways. The first 10 locomotives were imported from ABB in Switzerland in 1995. They are supposed to be a variant of the Lok 2000. Chittaranjan Locomotive Works (CLW) started production in 2000. It was designed to haul 18 coach passenger trains at 162 km/h (101 mph). It is the first 3-phase locomotive in India.
Other notable features of this locomotive are the provision of taps from the main transformers for hotel load, pantry loads, flexible gear coupling, wheel-mounted disc brakes, and a potential for speed enhancement to 225 km/h (140 mph). Braking systems include regenerative braking (160kN), loco disc brakes, automatic train air brakes, and a charged spring parking brake. MU operation possible with a maximum of two locos. At trials, a WAP-5 has been tested up to 184 km/h (114 mph).
The WAP-5 series of locomotives haul the premium trains on Indian Railways like the Mumbai Rajdhani Express, Bhopal Shatabdi Express, Lucknow Shatabdi Express, Prayagraj Express, etc. The Bhopal Shatabdi hauled by a WAP-5 travels at 150 km/h (93 mph) in the New Delhi - Agra Cantt section.
Around 45 of these locomotives have been put to service as of December 2011.
