The Indian Ministry of Railways has set an ambitious target to complete the Detailed Project Reports (DPRs) for three high-speed rail corridors by March 2027. These corridors include the Hyderabad-Chennai, Hyderabad-Bengaluru, and Patna-Siliguri routes, with the latter being part of the larger Varanasi-Siliguri high-speed rail initiative. Announced by Finance Minister Nirmala Sitharaman in the Union Budget for 2026-27, these projects aim to significantly reduce travel times across key urban centers. For instance, the Hyderabad-Chennai bullet train is expected to cut travel time to about 2 hours and 55 minutes, while the Hyderabad-Bengaluru route will take just 1 hour and 13 minutes. The Railway Board has tasked the National High-Speed Rail Corporation Limited with overseeing the swift implementation of these projects, which also include corridors like Mumbai-Pune and Delhi-Varanasi. Additionally, the Ministry is working on the country's first bullet train, the 'B28', which is expected to be manufactured by March 2027. This train will feature a design speed of 280 km/h and an operational speed of 250 km/h, along with modern passenger amenities.
