In 2025, Indian Railways achieved two landmark connectivity milestones that transformed the nation's rail map. In June 2025, the Prime Minister inaugurated the final 63-km Katra–Sangaldan section of the 272-km Udhampur–Srinagar–Baramulla Rail Link (USBRL), formally integrating the Kashmir Valley into the national rail network. The project features the world's highest railway arch bridge — the Chenab Bridge (359 m high, spanning 1,315 m), India's first cable-stayed railway bridge (Anji Bridge, deck 331 m above river), and India's longest operational railway tunnel (T-50). A Vande Bharat service between Katra and Srinagar marked the operational start. Separately, in September 2025, the 51-km Bairabi–Sairang broad-gauge line in Mizoram was inaugurated, making Aizawl the fourth northeastern state capital to be linked to Indian Railways, after Guwahati (Dispur), Agartala, and Itanagar. The first freight movement on 14 September 2025 carried 21 cement wagons from Assam to Aizawl. These milestones symbolise national territorial integration, strategic connectivity in border regions, and the transformative role of infrastructure in India's development journey.
