The Indian locomotive class WP was a class of 4-6-2 "Pacific" steam locomotives used in India. It was introduced after World War II for passenger duties, marking the change from 'X' to 'W' as the classification code for broad gauge locomotives. The class was designed specifically for low-calorie, high-ash Indian coal, by Railway Board designers in India.
WP class locomotives were capable of going up to 110 km/h (68 mph) and were easily recognized by their cone-shaped bulging nose, usually with a silver star device painted on it.
