All type of coaches of passenger trains have been given special attention in order to avoid the possibility of untoward incidents due to breakage of springs, loose types on the wheels and other failure of mechanical equipment’s.
During the period from January till November of this current year 1139 no’s of coaches were out turned after POH from the two workshops of N. F. Railway i.e. New Bongaigaon & Dibrugarh. In New Bongaigaon workshop POH of 301 Non Air-Conditioned Conventional coaches, 51 Air-Conditioned Conventional coaches, 93 Non Air-Conditioned LHB coaches & 122 Air-Conditioned LHB coaches were done.

Production of new coaches for replacement of over-aged stock is a continuous process on Indian Railways.
