Come October, 14 Alternating Current-Direct Current (AC-DC) trains will run on the harbour line, between Andheri and Chhatrapati Shivaji Terminus (CST).
At present, eight such trains are running on this route, of which three are the new Siemens-make trains.
The white-and-violet Siemens trains are better ventilated and conserve only 30-40% energy, as compared to the older trains.
These trains, according to Central Railway (CR) officials, are being brought in view of the conversion of Western Railway’s (WR) network from DC to AC.
From Andheri to Mahim, the Harbour trains share the same stations as the Western Line, which will be converted to AC. From King Circle to CST, the line is DC.
The AC-DC trains will be able to ply on both types of lines.
“We are waiting for the monsoon to get over to complete the conversion. The work of converting the 1,500V DC to 25,000V AC will be done by end October,” said Sharat Chandrayan, chief PRO, WR.
“Keeping in mind the WR conversion, and to ensure commuters have a smooth journey, we are converting 14 trains, which can run on AC line. Our trains will be ready by the time the WR completes the conversion,” said VA Malgaonkar, chief PRO, CR.
