Vande Bharat Sleeper (trainset)
The Vande Bharat Sleeper trainset, formerly known as Train 20, is a semi-high-speed, long-distance electric multiple unit developed for the Vande Bharat Sleeper services of the Indian Railways. It was developed by the Integral Coach Factory based on the Vande Bharat trainset, with modifications to the exterior, added sleeping berths, and other amenities to cater to long-distance service.
