Unlike say Thane-Dadar, the section has no other line where we could have diverted the slow trains.Charred insulation of the overhead wire caused the power failure.Commuters travelling towards CST from Thane and beyond were inconvenienced when around 20 services were cancelled and 80 were delayed after the overhead wire failed near Mumbra on Saturday. Commuters travelling towards CST from Thane and beyond were inconvenienced when around 20 services were cancelled and 80 were delayed after the overhead wire failed near Mumbra on Saturday. “When the insulation gets damaged, as a fall back, the system automatically shuts down power supply on that section, in this case it was from Diva to Thane,” said an official on the condition of anonymity. The incident occurred at 1 pm and lasted until 2. The 80 services were delayed from 15 to 45 minutes until the traffic was resumed along with the 20 cancellations.However, the biggest China RG7/U Cables relief for the central railway (CR) was that being a weekend, there were not many commuters travelling than on any other weekday. The CR has already seen two big failures on its line, on May 25 and June 1, with the first on the mainline near Vikhroli causing over 69 cancellations and latter taken place on the Harbour line near Vadala that lead to near 80 services being cancelled.30 pm when the services were resumed. According to officials, dearth of alternate lines between Diva and Thane where the trains could have been diverted caused the disruption. The fast track in that section, is already being used for outstation trains and fast locals due to which the delay and cancellations were unavoidable,” further added the official.
