Duronto Express is a category of long-distance non stop source to destination trains run by the Indian Railways. Initially these trains did not have any ticketing stops between the origin and the destination, but since January 2016 it is possible to book tickets from those technical stops. "Duronto" means "restless" in Bengali language. These trains' coaches have characteristic yellow-green livery. Duronto Express services connect the several metros and major state capitals of India. These trains are faster than Rajdhani and Shatabdi express.
