Guwahati: Aimed at enhancing the operational efficiency and safety of train operations, the Northeast Frontier Railway (NFR) has replaced the existing 1 in 12 track turnout at the Langting station yard in Assam’s Lumding-Badarpur hill section with a more safe 1 in 16 turnout set.
This marks a milestone achievement, as for the first time such an upgradation has been adopted and implemented under the jurisdiction of the NFR.

The previous 1 in 12 turnout of Langting yard was laid on a 3.5-degree curve resulting in a sharp curvature of the crossover at 7.5 degrees. This sharp curvature posed challenges in maintaining smooth train operations.

By installing the 1 in 16 turnout set, the resultant curvature has been significantly reduced to 5.73 degrees thereby facilitating safer and more efficient train movement through the yard.
The replacement process involved meticulous planning and execution with multiple rounds of machine tamping conducted using MFI technology that further stabilises the tracks and ensures optimal alignments.
