India, Nov. 22 -- The Central Railway (CR) has scheduled six mega blocks over the weekend and the following week across the Main, Harbour and Trans-Harbour lines, causing disruptions to several suburban and long-distance services. The blocks are essential for infrastructure upgrades, including launching girders, track structure replacements and installation of electronic interlocking systems, officials said.

On November 23, a mega block will be operated on the Main line between Thane and Kalyan from 10:30 am to 3:40 pm for engineering and maintenance work. During this period, suburban services will run on the slow line with halts at Kalwa, Mumbra and Diva, resulting in delays. Long-distance trains will be diverted to the fifth line.
