With a remarkable progress of 200 Track Kilometre of Rail Renewal works, Northeast Frontier Railway registered ever best progress in the history of NFR. The remarkable figures have been achieved executing renewal works in both Primary and Secondary categories only up to 1st November during this year.Previous best has been 200.29 Track Kilometre in whole year during 2020 - 21. This will enhance safety and will pave way for increase in speed in train running.
Railway tracks are maintained and inspected on regular intervals to ensure that every section is fit for train operations. Railway tracks are replaced through track renewal works which is an ongoing process. Track renewal works are undertaken as and when a stretch of track becomes due for renewal on the basis of criteria laid down in Indian Railway Permanent Way Manual (IRPWM). Some of the criteria listed are- traffic carried in terms of gross million tonnes, incidence of rail fracture/failure, wear of rails, corrosion of rails and maintainability of track as per standards etc.
