Lalmonirhat Junction railway station

North Bengal State Railway opened a metre gauge line from Parbatipur to Kaunia in 1879. Two narrow gauge lines were laid by Eastern Bengal Railway from Kaunia to Dharla River, thereby creating the Kaunia–Dharlla State Railway. The Kaunia Dharla railway lines were converted to metre gauge in 1901. The Kaunia-Dharla line was extended to Amingaon in 1908.[1][2]

By the turn of the century Lalmonirhat had emerged as an important railway centre. Bengal Dooars Railway constructed a line to Malbazar. Links were established with Assam, with the Golokganj-Amingaon line coming up.[1]

Prior to the partition of India, the prestigious Assam Mail used to travel from Santahar to Guwahati via Lalmonirhat.[3]

Note: The map alongside presents the position as it stands today (2020). The international border was not there when the railways were first laid in the area in the 19th–20th century. It came up in 1947. Since then, it has been an effort to live up to the new realities. The map is 'Interactive' (the larger version) – it means that all the places shown in the map are linked in the full screen map.
