Maligaon, February 20 (MExN): Northeast Frontier Railway (NFR) has completed major curve realignment work between the Simaluguri and Moranhat sections in the Tinsukia Division, leading to the removal of a permanent speed restriction (PSR).
Official stated that the project involved complex engineering activities, which were executed smoothly during a traffic block with close coordination among the Engineering, Operating, and Traction Distribution (TRD) departments. The existing 4-degree curve was realigned and connected with a newly laid 2-degree curve, while new Overhead Equipment (OHE) wires and masts were installed to ensure seamless electric traction operations over the realigned stretch.
The section previously had a curve of 400 metres length with a 4-degree curvature. Under the new alignment, a 660-metre-long curve of 2-degree curvature has been laid on a newly developed formation of approximately 650 metres. The maximum slew carried out during the realignment was 27.77 metres, reflecting the scale and precision of the engineering effort.
As part of the infrastructure enhancement, a new Bridge No. 31 with a span of 4m x 4m and a total length of 10.2 metres has also been constructed on the newly formed alignment. The new bridge and formation are expected to ensure improved track stability, safety, and long-term durability of the section.
With the completion of this work, the Permanent Speed Restriction of 80 kmph over a stretch of 400 metres has been permanently removed. The track is now fit for Maximum Permissible Speed (MPS) of 110 kmph, which will significantly improve train mobility, reduce travel time, and enhance punctuality.
