NFR Strengthens Maintenance of Coaches with Modern Technology

 

Guwahati, 08 January, 2026: Northeast Frontier Railway (NFR) has introduced advanced Fluke ii905 Acoustic Imager technology at the Sick Line and Pit Line, Guwahati Coaching Depot, to strengthen detection of air brake and pneumatic system leakages and enhance coach safety.

The acoustic imager is being used for fast, visual detection of DV leakage, air bellow leakage and air brake pipe leakage. The technology enables precise pinpointing of compressed air and gas leaks through an acoustic sound map overlaid on visible images, ensuring accurate, safe and time-efficient diagnosis. This initiative significantly improves reliability of air brake leakage detection, reduces diagnostic time and supports timely rectification, thereby enhancing operational efficiency. To ensure effective utilization, training has been provided to Pit Line staff on operation of computerized RTR machines and use of advanced diagnostic tools at Guwahati Coaching Depot.

In addition, Sick Line/Guwahati has undertaken the “One Day One Coach–INTENSIVE” initiative, under which one coach is taken up daily for comprehensive overhauling. Works include exterior painting, fitment of passenger amenities, changing of berth rexine, linen storage repairs, installation of new EPPF cylinders in lavatories, provision of new dustbins and side mirrors. So far, three coaches have been completed under this initiative.

These measures reaffirm Northeast Frontier Railway’s commitment to passenger safety, quality maintenance and continuous upgradation through modern technology.
