A brand-new suburban railway line connecting the harbour line (Panvel) with the main line (Karjat) of Central Railway — designed to decongest Mumbai’s existing overcrowded corridors — will also facilitate connectivity with the Navi Mumbai International Airport. This will be Mumbai suburban railway’s sixth corridor after the main, harbour, trans-harbour, and port lines (all of CR), and the western line. According to officials, to ensure those residing in a cluster of houses at Chowk that came in the path of the new rail line weren’t displaced, the alignment was tweaked a bit, preventing the dismantling of the structures.
