Introduction of high speed corridors should also address the following areas Rail accidents due to poor vehicle/track interaction, Monitoring of discontinuity in rails by continuous track circuiting and automatic block signaling, Understanding of safety-critical limits of wheel/rail dynamic behavior, Safety criteria for the prevention of wheel mount and other derailments, Safety guidelines for wheel/rail profiles and contact conditions and the necessity of rail grinding, Limits for maximum passenger ride safety and comfort, Elimination of Rail/weld failures, Prevention of lateral buckling, Noise and vibration control of high speed train traffic, Integration of high speed and low speed train traffic and the impact on the environment due to high emission and magnetic radiation levels.
