The Western Railway (WR) covered almost 70 per cent of its suburban network with advanced digital technology in order to prevent signal failure during heavy rains.
WR Chief PRO Ravinder Bhatkar said that they had provided digital axle counters in dual detection mode across 1,165 of 1,610 track circuits.
