The tunnel, among many other things, is part of the Railway pavilion, which was inaugurated by Railway Board Chairman Arunendra Kumar.
The pavilion, with a pristine appeal and a futuristic outlook, is also showcasing Railways' important units through static and working models for the visitors.
The opening of the 12 km-long Pir Panjal rail tunnel has paved the way to an all-weather connectivity into the Kashmir Valley throughout the year.
Constructed at an estimated cost of Rs 1300 crore, the longest rail tunnel in the country connects the Banihal in Jammu with Qazikund in Kashmir. It is part of the 345-km Jammu-Udhampur-Srinagar-Baramulla rail line, aimed at connecting Jammu with Baramulla.
