Guwahati, November 13 (MExN): The Northeast Frontier Railway (NFR) has been able to allot greater time for renewal of assets due to systematic planning in train operations, an official claimed today. Timely maintenance of assets like tracks, points and crossings, minor bridges, girders, over bridges etc. are vital for safety of passenger and operation of train services, NFR CRPO Pranav Jyoti Sharma informed in a press note. Due to increase in numbers of trains over the years, availability of time period for renewal as well as repair of assets continued to decrease over the time but some precise planning leading to planned cancellations of trains on lean demand days viz. Sundays has lead to a big increase in the allotment of traffic block, it said. On September, 2016 only 53% of the time was sanctioned for undertaking renewal as well as repair of assets but it increased to 93.73% during the same month in 2017, it added. Due to meticulous planning, available maintenance time of 48.48% on October last year also improved up to 81.11% this year.
