Board member reviews electrical conversion works on Harbour and Trans-Harbour line

Mumbai: Railway Board electrical advisor M.C. Chavan who visited the city took a review of the work regarding the conversion of the Harbour and Trans-Harbour line from Direct Current (DC) to Alternate Current (AC) which will increase the capacity of the Harbour and Trans-Harbour by three-times.

Central Railway (CR) divisional railway manager, Amitabh Ohja, said, “The meeting was held in connection to many projects in the state and the Harbour and Trans-Harbour conversion for Mumbai; the meeting was held since the conversion is due in March next year and, yes, it will add capacity to the Harbour and Trans-Harbour.”

Officials present in the meeting said that although the electrification process from Pune to Daundh was being talked about, the CR officials were keen to put forward the issues that were still unresolved for Harbour conversion. “The Railway Board is aware of the need of the project due to the increase in the number of passengers on both these lines, and especially, the Trans-Harbour was discussed, because of the whopping number of commuters in the past three to four years,” said an official on condition of anonymity.

According to the figures available with CR, the biggest increase has been seen at Koparkhairane station on the Trans-Harbour with almost 17 per cent increase since 2013, 2014 and the first half of 2015. Another station on the same line, Rabale, too has seen an increase of commuters by 13 per cent in the same period.

Other issues were pointed out in the meeting such as the railway overbridges (ROB) at Reay Road, Tilak Nagar and Chembur. “We have informed the Board that most of the work has been completed between Vashi and Panvel and the problem is only on these bridges which too need to be rectified and safety sanctions are required to be applied accordingly,” added the official.

One of the major lessons learnt from the same conversion done on CR’s mainline in June The insulation around the overhead-wire has already been changed to take the increased voltage of AC which is 25,000 volts from DC’s 1,500 volts. He said this was one of the major lessons learnt from the experience on CR’s mainline. This insulation process had not been completed on the mainline before the conversion due to which engines of the trains saw short-circuits and the pantograph was not able to take the heat, causing delay and cancellation of services throughout June and early July this year.
