Local train services on both up and down slow line between CST and Wadala stations of Harbour line were shut for third day on Sunday as part of a 72-hour megablock to undertake extension work on the platforms.
The three-day shutdown was imposed to extend platforms on the line to accommodate 12-car rakes. The Central Railway aims to start the 12-car service on Harbour line from June this year to deal with increasing traffic, a senior railway official said.
The DC to AC conversion work would be undertaken soon after the extension of platforms. The 12-car rakes will be supplied by the Western Railway, he said. On Sunday being a holiday comparatively lesser number of commuters faced hassles.
