Indian Railways reached another milestone on February 20 as Prime Minister Narendra Modi inaugurated the longest transportation tunnel in India, christened ‘T-50,’ on the Udhampur-Srinagar-Baramulla Rail Link (USBRL).  As the first electrified trains of the Kashmir valley embarked on their inaugural journey, a new chapter unfolded in India's rail infrastructure.

Two electrified trains embarked on their maiden journeys, one from Srinagar to Sangaldan and the other in the reverse direction, setting the wheels of progress in motion.

In his address, Prime Minister Modi articulated a vision beyond boundaries, envisioning a day when a train journey from Kashmir to Kanyakumari would be a reality. The T-50 tunnel, spanning 12.77 kilometers, nestled between the Khari-Sumber section, was not only inaugurated but also the 48.1-kilometer Banihal-Khari-Sumber-Sangaldan section, further expanding the reach of the USBRL.

The T-50 tunnel is one of the most formidable engineering feats of the USBRL project. Commencing its survey in 1996, the tunnel saw the light of operationalization only in 2013. Safety remained paramount, with meticulous planning evident in the construction of an escape tunnel running parallel to T-50, equipped with connecting passages every 375 meters for swift evacuation during emergencies. The provision of water pipes along the tunnel's length showcased a proactive approach towards fire safety.

The narrative extended to T-49, India's longest escape tunnel, which achieved a breakthrough in December 2022. Stretching 12.895 kilometers between Sumber and Khari stations, T-49 epitomized innovation and meticulous engineering. As a twin-tube tunnel, comprising both main and escape tunnels, it added another layer of resilience to the USBRL project.

The USBRL project, sanctioned in 1994-95, is nearing fruition, with 209 out of 272 km already commissioned in phases. Notable segments include the Qazigund-Baramulla section, the Banihal-Qazigund stretch, and the recent Banihal-Sangaldan section. Additionally, architectural marvels like the Chenab bridge, the world's highest railway arc bridge, and the Anji bridge, the first cable-stayed bridge of Indian Railways, promise to redefine travel experiences.
