Faced with the challenging Himalayan terrain, Indian Railways engineers have devised an innovative tunnelling method to overcome the construction obstacles in Tunnel-1, a crucial component of the 111-km-long Katra-Banihal section of the Kashmir rail link project.
This 3.2-km-long single tube tunnel, situated at the base of the Trikuta Hills in the Katra-Reasi section of the Udhampur-Srinagar-Baramulla Rail Link Project, is considered one of the most formidable sections of the entire project.
