Central Railway will expand its suburban fleet from August 15 by upgrading 22 local services from 12 coaches to 15 coaches, adding capacity for commuters on the main line. The additional coaches increase carrying capacity by around 25% per upgraded train. The change also raises the total number of 15-coach local services on Central Railway to 54.

The upgrades affect peak and main-line routes, with several services highlighted for morning and evening operation. Sources note that 15-coach services rise from 32 to 54, with 11 of the 22 upgraded trains running during peak hours. While the Times of India focuses on the overall increase in passenger capacity and service count, the Free Press Journal details route impacts, including services involving CSMT–Karjat and Khopoli–Karjat, and references changes to some train destinations. The overall number of suburban services is reported to remain unchanged at 1,820, even as more trains use longer rakes to reduce crowding on key corridors.
