The Loco Story :

Imported from ABB Zurich, Switzerland (30000 - 30011). Later Chittaranjan Locomotive Works started indigenous production in 2000.

Maximum speed limit - 162kmph. Top Speed - 225 kmph. Maximum power output - 5450 hp.

Designed to haul 18 coach passenger trains at 162 kmph making it the fastest locomotive in Indian conditions. It is the first 3-phase locomotive class in India.

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 kmph.

Braking systems include regenerative braking (160 kN), loco disc brakes, automatic train air brakes, and a charged spring parking brake.

Fastest train of India the NDLS-Bhopal Shatabdi hauled by a WAP-5 which travels at 160 kmph.

The original design was to have air-conditioned cabs. However the idea has been scrapped due to controversy over costs and fitment and the first units made by CLW do not have air-conditioned cabs. As of now only WAP5 # 30000 have ac cabs.
