Metro trains on two of the 10 lines will start commercial operations from May 2021 as the construction authority, Mumbai Metropolitan Regional Development Authority (MMRDA), announced on Thursday that they have pressed a large amount of labour and energy into the project to tide over delays due to the pandemic.

Mumbai is getting a 337-km Metro rail network with 10 lines over the next few years. "Line 2A and Line 7, between Andheri and Dahisar in west and east respectively, will change the face of western suburbs and ease the traffic crisis. The lines will be linked to the existing Mumbai Metro Line 1 and other upcoming Metro lines," MMRDA commissioner RA Rajeev said.
