The Indian Railways has rolled out upgraded sleeper rakes of the Tejas express to facilitate better travel experience with enhanced comfort. The prestigious Mumbai Rajdhani Express train will use these bright golden-hued coaches, which have been enhanced with smart features, to provide the best in the class travel experience. This new rake made its first run on Monday. The Rajdhani Express will have two Tejas sleeper coach rakes. One of the rakes contains the first Tejas Smart sleeper coaches to be introduced on Indian Railways. The new train will be equipped with advanced smart features that will improve passenger safety and comfort. With the help of intelligent sensor-based systems, the smart coach aims to provide world-class facilities to passengers.
