RRB Practice 3

The Vande Bharat Express is India's first indigenously designed and manufactured semi-high-speed trainset, developed under the Make in India initiative by the Integral Coach Factory in Chennai with engineering inputs from the Research Designs and Standards Organisation and support from domestic component manufacturers across the country. First introduced into commercial service in February 2019 on the New Delhi to Varanasi route, the train represents a generational leap in the quality and speed of intercity rail travel available to Indian passengers and a landmark validation of India's capability to design and manufacture complex railway rolling stock without dependence on foreign technology. The train features a self-propelled distributed traction architecture in which traction motors are distributed across multiple coaches throughout the trainset rather than being concentrated in a single locomotive at the head of the train, enabling faster acceleration from rest to line speed, superior braking performance, and better utilisation of the available track capacity compared to locomotive-hauled trains of conventional design. The passenger experience in Vande Bharat Executive and Chair Car coaches is substantially superior to conventional express train coaches, with sealed gangway connections between coaches that eliminate the noise and dust ingress typical of conventional trains, automatic sliding doors controlled by sensors, ergonomically designed aircraft-style reclining seats, individual reading lights and mobile charging sockets at every seat, a centrally controlled air-conditioning and pressurisation system, an onboard infotainment system providing information about station stops and speed, and controlled discharge toilet systems that are more hygienic and environmentally responsible than the direct discharge systems prevalent in older rolling stock. The train's maximum design speed of one hundred and sixty kilometres per hour makes it significantly faster than the average speeds achievable with conventional locomotive-hauled stock on most routes, and it has successfully completed trial runs at speeds exceeding one hundred and eighty kilometres per hour on specially prepared sections of track, demonstrating the potential for further speed enhancement as infrastructure is upgraded. Subsequent generations of the Vande Bharat platform have been developed to extend its applicability to a wider range of railway requirements, with sleeper variants featuring berths for overnight long-distance travel under development at the Integral Coach Factory and other production units, while the Vande Metro variant with a shorter formation and higher passenger density per unit length is designed for shorter suburban and intercity corridors with frequent station stops. The Vande Bharat fleet has been progressively expanded across the country with trains now operating on dozens of routes connecting all major regional centres, and the government has set ambitious targets for the addition of hundreds of new Vande Bharat trainsets over the coming years to progressively replace older rolling stock across the network. The success of the Vande Bharat programme has generated significant downstream industrial benefit, with domestic manufacturers of seats, air-conditioning systems, electronics, couplers, brakes, and other components developing the technical capability to supply world-class railway equipment for both the domestic market and potential export customers in other developing countries seeking to modernise their rail systems.
