Rishikesh Karnprayag New Rail Line
India, Rishikesh
2023 – today

The 125 km long Rishikesh-Karnaprayag rail line project, with 12 stations, 35 bridges, and more than 100 km of tunnel, is making swift progress. This rail link aims to provide last-mile connectivity between Rishikesh and Karnaprayag. Around 20 km of tunnel along the underground construction of the track will be built by two Herrenknecht Single Shield TBMs, which can achieve high advance rates in hard rock conditions. Both machines with 9 meters in diameter successfully went through factory acceptance in spring 2022. Both TBMs are poised to work for the excavation through the Chandpur Formation, dominated by phyllite. Four multi-service vehicles and a 10 km belt conveyor system will be in operation supporting the tunnelling process. Once the Rishikesh-Karnaprayag rail line project is completed, it will cut the travel time between Rishikesh and Karnaprayag from 7 hours to just over 2 hours. It is expected that the new rail line will boost the socio-economic and cultural development in the region.
