Shortage of rail lines has forced railway works to stop in their tracks. Both Central and Western Railway have a number of projects slated for completion by March 2019, but they might not meet this target if they don't get an adequate supply of rail tracks in time. In Mumbai, this includes the third line between Kalyan and Kasara, and the fifth and sixth lines between Diva and Thane.

During a recent the Infrastructure Works Review meeting, CR and WR managers told the railway board that they would only be able to meet the March 2019 deadline if they get enough rail supply in time. The shortage has delayed several projects such as laying of new lines, gauge conversion and doubling existing lines.
