|How to interpret this infobox|
The Northern Bengal State Railway (NBSR) was one of the first metre gauge(MG) lines to be constructed opening in 1874 from Sara Ghat, on the left bank of the Padma River. Initially built only as far as Chilahati but later extended to Siliguri , the NBSR branched west at Parbatipur to Dinagepore and east to Kaunia.
At the same time, a broad gauge(BG) extension of the Eastern Bengal Railway(EBR) from Poradaho to Damukdia on the right bank of Padma, opposite Sara Ghat branched off and extended eastward. Passengers crossed the river Padma by railway operated steamer ferry using the Sara Train Ferry 
With the later extension of the NBSR in 1879 to Siliguri the journey from Calcutta to Shiliguri became possible without a break. At Siliguri , in the foothills of the Himilayas, there was a connection with the Darjeeling-Himalayan Railway (which opened 1879-81)
