The Jammu-Udhampur-Srinagar-Baramulla Railway Link project aims to connect the Kashmir valley to the Indian railway network via a 345km route. It is divided into four sections, with the most challenging being the 129km Katra-Qazigund section that requires extensive tunneling and bridge construction, including a 359m tall Chenab bridge and 11km Pir Panjal tunnel. The project faces geological and security challenges but aims to improve transportation and economic development in the region.
