Railway HR POINT NCR RCR WLR PCR Circuits At HR stage all the conditions to be satisfied for clearing a signal are proved. Crank handles are ‘in’, i.e. proved by CHLRs up and CHFRs down. Route Release Relays have de-energized after the last train movement i.e UYR1, UYR2 etc., are down. No cancellation is initiated […]
