Résumé: To operate a railway safely and to keep it in a healthy condition constant input in maintenance and renewal is needed. India falls short in keeping the Quality of its rail-tracks fit for the traffic load/volume the tracks have to carry. This is one of the underlying factors/conditions for the unsafe and uneconomical operation of Indian Railways. Train-Passengers are killed and injured in nasty and unwanted bad events.
With modern highly powered three phase AC asynchronous Traction/Slip-Control Technology (high accelerating and decelerating/breaking forces) the problems of Rail Contact Fatigues (RCF), resulting in rail surface defects like Head-Checks, Squats, Studs, Spallings and Roughness, are on increase.
Rail surface defects have to be eliminated by preventive Rail-Grinding in an early state. If one let the defects to grow too deep, rails might fracture resulting in fatal Derailment-Disasters, killing and injuring train-passengers.
In order to keep Railway Tracks in a sound and healthy condition, assuring nearly Zero Derailments, Railway Tracks must be available for well planned CONDITION BASED and PROACTIVE MAINTENANCE and RENWEAL through modern Railway Track Engineering and Technologies. Digital tools will help to achieve this perspective.
