Lumding–Sabroom section

The British introduced 6 important trains after the long Guwahati-Lumding- 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 In 1947 after partition, 4 trains were permanently withdrawn with only 2 MG trains between Guwahati and Silchar running until 1992.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 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 Kumarghat–Agartala railway line project was laid in 1996. The 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 broad gauge in 2016. A new -long track was laid from Agartala to Udaipur, Tripura in 2017. The remaining long track to Sabroom at the bank of Feni River at Bangladesh border was completed by 2019 and became operational on 3 October 2019. ==Important stations==
