*The* WAP-7 is a powerful, broad-gauge AC electric passenger locomotive developed by Chittaranjan Locomotive Works (CLW) for Indian Railways, known for its reliability and ability to haul high-speed passenger trains like the Rajdhani Express. It features 6,000 horsepower, operates on a 25 kV AC system, and is capable of speeds up to 140 kmph, with some versions even reaching 160 kmph. A key feature is its Head-On-Generation (HOG) capability, which provides power to the coaches for air-conditioning, eliminating the need for separate generators on the train and reducing maintenance costs.
