GUWAHATI, Aug 2: The rolling stock workshops at New Bongaigaon and Dibrugarh under Northeast Frontier Railway (NFR) have made notable achievements in the maintenance of train coaches and goods wagons. In July 2024, both workshops exceeded their targets for Periodical Overhauling (POH) of coaches and wagons, highlighting NFR’s commitment to innovation, safety, and operational excellence.
Safety is paramount for train operations, and NFR has implemented several initiatives to ensure this, including regular maintenance of coaches and wagons to provide a smooth riding experience for passengers. The New Bongaigaon workshop conducted POH on 64 Non-AC and AC conventional coaches during the period. The Dibrugarh workshop also surpassed its target by carrying out POH on 59 conventional coaches, exceeding the target of 56.

Additionally, three non-high-speed trolleys were converted into high-speed trolleys, and 38 in-house items were manufactured at the New Bongaigaon workshop. Both workshops have undertaken infrastructure upgrades to refurbish Linke Hofmann Busch (LHB) coaches and increase their POH capacity. The Dibrugarh workshop installed Fire Detection Systems (FSDS) in two LHB AC coaches, bringing the total to 28 this fiscal year.
The maintenance and repair of train coaches and goods wagons adhere to the prescribed schedules. Besides POH, Intermediate Overhauling (IOH) is regularly conducted. The New Bongaigaon workshop converted 25 wagons to the Twin Pipe air brake system, reaching a total of 126 for the year. The Dibrugarh workshop modified the R3 air hose pipes of seven coaches, bringing the total to 38 for the fiscal year. Additionally, air brake pipes and fittings were upgraded in 13 coaches during July, making a total of 49 coaches modified this fiscal year. The twin pipe brake system enhances operational efficiency and increases the average speed of freight trains by reducing brake release time.
During POH and IOH, all components, including the undergear of train coaches, are meticulously examined for corrosion, structural damage, and stability to ensure the coaches’ fitness and safe train operations.
