History

The British introduced 6 important trains after the 363 kilometres (226 mi) long Guwahati-Lumding-Badarpur Junction MG line was completed in 1914. These were 2 MG trains between Guwahati and Silchar, 1 MG train between Silchar & Sylhet, 1 MG Train between Silchar & Dhaka, 1 MG Train between Dhaka & Hailakandi & 1 between Guwahati & Dhaka. In 1947 after partition, 4 trains were permanently withdrawn with only 2 MG trains between Guwahati and Silchar running until 1992. After conversion of Guwahati–Lumding to broad gauge in 1992, the originating and ending station of these train was changed to Lumding. Post partition, Railway service was established in Tripura in 1964^[1] by constructing metre gauge track from Karimganj to Dharmanagar and Kailashahar in Tripura, but the track did not connect the state capital Agartala. The foundation stone of the 119 kilometres (74 mi) Kumarghat–Agartala railway line project was laid in 1996. The 87 kilometres (54 mi) long segment from Manu to Agartala became operational in 2008. It was a meter-gauge single track without electrification. The 5695/15696 Lumding-Agartala Express was started in 2008. In 2014, all trains were stopped & the line was converted to 1,676 mm (5 ft 6 in) broad gauge in 2016. A new 44 kilometres (27 mi)-long track was laid from Agartala to Udaipur, Tripura in 2017. The remaining 70 kilometres (43 mi) long track to Sabroom at the bank of Feni River at Bangladesh border was completed by 2019 and became operational on 3 October 2019.

Future construction

The track may be extended further from Sabroom to Chittagong port which is 75 km from the India–Bangladesh border. A branch line from Agartala to Akhaura in Bangladesh, is under construction. This line will reduce the distance between Kolkata and Agartala to about 729 kilometres (453 mi), from current about 1,550 kilometres (960 mi) via Guwahati. But Indian Government have suspended the project after 5th August 2024 owing to Political Chaos in Bangladesh.
