Guwahati: The Northeast Frontier Railway (NFR) has strengthened rail safety and operational efficiency across its network by commissioning a range of modern detection and inspection technologies aimed at preventing accidents and improving maintenance practices. As part of efforts to enhance rolling stock safety, NFR has successfully commissioned 30 Hot Box Detectors at key locations across its network. These detectors continuously monitor the temperature of axle box bearings in moving trains and help in early detection of overheating, commonly referred to as “hot box” conditions, which can lead to derailments if left unchecked. In addition, 43 more Hot Box Detectors are currently under procurement to further expand the safety monitoring system.
To improve the reliability of freight operations, three Automatic Train Examination Systems (ATES) have been installed at New Jalpaiguri. These systems automatically identify wheel defects, axle box issues, damaged or missing wagon doors and other abnormalities. By capturing critical data before trains enter examination depots, ATES enables maintenance teams to plan timely repairs, reduce inspection time and ensure smoother freight movement.

In another initiative, NFR has commissioned a test rake of five wagons fitted with test weights in the Rangiya Division to calibrate Electronic In-Motion Weigh Bridges. Currently, 15 such weight bridges are operational across the NFR network, and the test rake will help ensure accurate and reliable weight measurements during train operations. These initiatives underline NFR’s commitment to leveraging modern technology to enhance safety, improve maintenance efficiency and ensure dependable rail services across the region.
