NEW DELHI — India’s first dedicated railway test track, under construction in Rajasthan, is expected to be completed by December 2025 with a total investment of Rs 820 crore, according to the Ministry of Railways.   The 60-kilometre track will enable advanced testing of rolling stock which includes high-speed trials for bullet trains, and introduce new capabilities in railway infrastructure. Once it becomes operational, the track will accommodate speeds of up to 230 kmph, marking a milestone for high-speed rail testing in India. Located near Sambhar Lake in the Jodhpur Division, about 80 kilometres from Jaipur, the track runs between Gudha and Thathana Mithdi in the Deedwana district. The new track marks a milestone for Indian Railways, allowing extensive testing without disrupting existing passenger services. In addition to bullet trains, the track will test high-speed, semi-high-speed, and metro trains in the future. Research Design and Standards Organisation (RSDO) will evaluate every parameter of train performance, including stability and safety on deteriorated tracks before any coach, bogie, or engine is cleared for regular use.
