Siliguri Junction (station code:- SGUJ) is one of the major and second largest railway station that serve the city of Siliguri located in Darjeeling district in the Indian state of West Bengal. The station has two types of gauges visible i.e. 1,676 mm (5 ft 6 in) broad gauge, & 610 mm (2 ft) narrow-gauge tracks for Darjeeling Himalayan Railway. It was opened in 1949. It formerly had the distinction of having three gauges visible but the metre-gauge line from Aluabari Road to Siliguri Junction was converted later into broad gauge. A few years ago, the trains used to run between Siliguri Junction to Naksalbari on the metre-gauge line. Siliguri Junction lies on three railway lines New Jalpaiguri–Alipurduar–Samuktala Road line, Katihar–Siliguri line and Darjeeling Himalayan Railway Line. This railway station also has its own locomotive shed i.e Diesel Loco Shed, Siliguri

With the railway routes badly disturbed by the partition of India in 1947, Siliguri Town railway station suddenly lost its preeminence as the broad-gauge link to Calcutta running across East Pakistan. With three metre-gauge lines, the new Siliguri Junction railway station became the main railway station in the area. The three metre-gauge lines were linked to Kishanganj and Barsoi, Assam and Haldibari. The narrow gauge Darjeeling Himalayan Railway was there. The short reign was over in the 1960s when a new broad-gauge line linked Siliguri with Calcutta, and subsequently, all railway lines in the area (excepting Darjeeling Himalayan Railway) were converted to broad gauge. The focus shifted in 1960 to a brand new broad-gauge station at New Jalpaiguri.
