Guwahati: The Alipurduar Division of Northeast Frontier Railway (NFR) has set a new benchmark in mechanised track renewal by achieving its highest-ever single-day output of 1,033 track metres using PQRS (Plasser’s Quick Relaying System) on December 23, 2025.
The milestone reflects the effective deployment of high-output mechanised track-laying technology, optimal utilisation of traffic blocks, and seamless coordination between the engineering and operating departments. The achievement marks a significant step forward in enhancing track renewal efficiency and strengthening railway infrastructure in the region.
As part of the ongoing track renewal programme, Northeast Frontier Railway has undertaken a total of 290.8 km of track renewal across its jurisdiction. Division-wise progress includes 51.33 km in Katihar Division, 29.77 km in Alipurduar Division, 75.19 km in Rangiya Division, 44.98 km in Lumding Division, and 69.96 km in Tinsukia Division, reflecting a focused and systematic approach to infrastructure upgradation across the zone.

PQRS, or Plasser’s Quick Relaying System, comprises compact, self-propelled cranes that significantly reduce maintenance costs. Widely used for both new track construction and the modernisation of existing track infrastructure, the system enables rapid replacement of rail panels within shorter traffic blocks. Additionally, it allows for the complete retrieval of old rail panels directly from the work site to the base, eliminating the need for separate freight carriage arrangements.
The successful execution of this high-output mechanised track renewal operation underscores Northeast Frontier Railway’s continued emphasis on modern maintenance practices, improved asset reliability, and enhanced operational efficiency, reinforcing its commitment to providing safer and more reliable rail services.
