GUWAHATI, March 4: Continuing on the path of excellence, the New Bongaigaon and Dibrugarh workshops under Northeast Frontier Railway (NFR) have achieved remarkable increases in the maintenance of train coaches and goods wagons. Both workshops have delivered a higher quantity of maintenance output for coaches and wagons during the month of February 2024. Overhauling of coaches and wagons is conducted to provide a comfortable travel experience to passengers and ensure safety in operations.
During February 2024, the New Bongaigaon workshop carried out Intermediate Overhauling (IOH) of 64 sets of Linke Hofmann Busch (LHB) and ICF (conventional type) trolleys, surpassing the target of 50 sets per month. Periodical Overhauling (POH) of 55 coaches (27 LHB and 28 ICF), including 2 power cars, was also completed during the month. Additionally, 206 wheel sets were turned out from the wheel lathe and supplied to divisions to reduce the detention of rolling stocks. Furthermore, 154 wagons and 6 brake vans were turned out with the conversion of 12 trolleys of 6 wagons into high-speed trolleys. Moreover, for effective and faster braking, 46 wagons were converted to the twin pipe air brake system from the conventional single pipe air brake system.
