Mumbai’s sprawling suburban rail network, a lifeline for millions of daily commuters, faces its routine weekend maintenance halt this Sunday, November 23, 2025. As is standard practice, both Western Railway and Central Railway schedule these mega blocks every Sunday to address critical upkeep on tracks, signaling systems, and overhead wiring. This ensures the infrastructure remains safe and efficient amid the city’s relentless pace. However, this weekend brings a targeted focus: while the Western Line breathes easy with no interruptions, the Central Line will endure a substantial block between Thane and Kalyan stations on both Up and Down fast lines, spanning from 1:40 a.m. to 3:40 p.m.
On the Central Line, disruptions will ripple through local services originating from Chhatrapati Shivaji Maharaj Terminus (CSMT). Trains departing between 9:34 a.m. and 3:03 p.m. will reroute onto the Down Slow line from Thane to Kalyan, making additional stops at Kalva, Mumbra, and Diva stations alongside their usual halts. Passengers should anticipate a 10-minute delay upon reaching their final destinations.
In the reverse direction, Up Fast and Semi-fast services leaving Kalyan between 10:28 a.m. and 3:40 p.m. will shift to the Up Slow line between Kalyan and Thane, again stopping extra at Diva, Mumbra, and Kalva before rejoining the Up Fast line at Mulund. These adjustments will also tack on about 10 minutes to arrival times at CSMT or other stops.
Long-distance travelers aren’t spared either. Down Mail and Express trains from CSMT or Dadar will be shunted onto the fifth line between Thane and Kalyan. Their Up counterparts, inbound to CSMT or Dadar, will take the sixth line from Kalyan to Thane or Vikhroli.
Shifting to the Harbour Line, commuters can expect uninterrupted service this Sunday, even as a separate 12-hour night block—running Saturday and Sunday evenings—looms between Belapur and Panvel stations. For those routes, planning ahead remains key.
Relief comes for other corridors: no mega block is set for the Western, Uran, or Trans-Harbour lines, allowing trains to operate on their regular timetables. As always, the Central Railway urges passengers to check official updates via apps or station announcements to navigate these changes seamlessly. With Mumbai’s trains carrying over 7 million riders daily, these blocks underscore the delicate balance between maintenance and mobility in India’s bustling financial hub.
