Taking note of the repeated signal failures, the Central Railway (CR) will begin an exhaustive repair and maintenance work of signals and other subsidiary works between Sion and Kalwa stations from May.
The entire work, that would be carried out over a period of one year, would cost approximately Rs72 lakh. As part of the work, the authorities would check every signal on the stretch, location boxes connecting wires and also those connecting the tracks with signals.
“Signals play an important role in train operations. So, it needs to be maintained regularly,” said V Malegaonkar, chief PRO, CR.
While on April 19, the train services got disrupted due to the accidental damage caused to the signal wire by a track-shifting machine, on April 4, there was a signal failure near Dombivli station. “Nearly 30% cases of disruption of services occur due to signal failure,” said a CR official on condition of anonymity.
“There have been cases where slum dwellers staying close to the railway tracks even burn garbage near the signalling system. A minor spark too results in failure of the system,” said another senior CR official.
Though the CR authorities have replaced the signals with LED bulbs, which they claim are durable and emit brighter light, they are finding it difficult to prevent the theft of wires in areas near Kurla, Thane and Kalwa.
