Indian Railways uses a class of electric locomotives called WAP-5. The WAP-5 series of locomotives haul the premium trains on Indian Railways like the Mumbai Rajdhani Express, Bhopal Shatabdi Express, Lucknow Shatabdi Express, Thiruvananthapuram Rajdhani, 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.
The first 10 locomotives were imported from ABB in Switzerland in 1995. They are supposed to be a variant of the Swiss Lok 2000 (Design Concept) and German DB Class 120 (Mechanical Chasis). 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 key features of the locomotive are the provision of taps from the main transformers for Head end power (HEP or 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 (160 kN), 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 185 km/h (115 mph).
Around 60 of these locomotives have been put to service as of January 2013.
