GUWAHATI, Feb 20: Northeast Frontier Railway (NFR) has successfully completed major curve realignment work between Simaluguri and Moranhat Sections in the Tinsukia Division, removing a Permanent Speed Restriction (PSR). The work marks a significant milestone in strengthening rail infrastructure and enhancing operational efficiency in the section.
The project involved complex engineering activities executed during the 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. New Overhead Equipment (OHE) wires and masts were also installed to ensure seamless electric traction operations.

Previously, the section had a 400-metre-long 4-degree curve. Under the new alignment, a 660-metre-long 2-degree curve has been laid on a newly developed formation of approximately 650 metres. The maximum slew during realignment was 27.77 metres.
As part of the enhancement, a new Bridge No 31 (4m x 4m, total length 10.2m) has been constructed on the realigned stretch, ensuring improved track stability, safety and long-term durability.
With the completion of the work, the 80 kmph PSR has been permanently removed. The track now permits a Maximum Permissible Speed (MPS) of 110 kmph, reducing travel time and enhancing punctuality.
This accomplishment underscores NFR’s commitment to modernising rail infrastructure, improving safety standards and providing faster, safer and more reliable train services across the region.
