1. The escape tunnel has been constructed to facilitate rescue work in case of an emergency, in response to railway officers. It passes by the Ramban formation of the Himalayas and apart from this, varied distributaries and drains of Chenab River like Khoda, Hingni, Kundan nallah cross all alongside the alignment, making drilling a extremely difficult process, in response to a government release.

2. This is the fourth tunnel on the Banihal-Katra route. In January this yr, a 12.75 km tunnel referred to as T-49 was accomplished. It has been constructed by the New Austrian Tunnelling Method (NATM), a contemporary strategy of drill and blast processes.

3. The horseshoe-shaped escape tunnel connects the Sumber station yard on the south facet and tunnel T-50, in response to a authorities launch. The elevation of the south finish at Sumber is roughly 1400.5 metres and of the north finish is 1558.84 metres.

4. Tunnel T-49 is a twin tube tunnel comprising the principle tunnel (12.75 km) and escape tunnel (12.895 km) linked with 33 cross-passages, in response to railways.

5. The Banihal-Katra part is being constructed as a part of the USBRL mission. Out of the full 272 kilometres of the mission, 161 km has already been commissioned and operationalised.
