The 12.89 kilometre tunnel, India’s longest escape tunnel, was finished on Thursday on the 111 km under-construction Banihal-Katra railway line in Jammu and Kashmir, authorities said, news agency PTI reported.
It is a component of the highly regarded Udhampur-Srinagar-Baramulla Railway Line (USBRL) project.
This is the fourth tunnel on the Banihal-Katra line, following the 12.75 km tunnel T-49 (India’s longest tunnel) that was finished in January of this year.
