Bholu the Elephant is the mascot of Indian Railways, represented as a cartoon of an elephant holding a signal lamp with a green ring in one hand. It was initially designed for the Indian Railways' 150th anniversary commemoration events and was unveiled on 16 April 2002 in Bangalore. In 2003, Indian Railways decided to permanently retain Bholu as its official mascot. A representation of Bholu was placed on the back side of an Indian coin.
