Traffic snarls, train service disruption

Amid intense showers, low-lying areas such as Andheri Subway, Hindmata Junction, Dadar, Gandhi Market, and Malad Subway were flooded, bringing traffic to a standstill. Waterlogging was also reported in the King Circle junction, forcing pedestrians and vehicles to wade through accumulated water.

To facilitate traffic movement, the civic administration deployed dewatering pumps across the city to clearfloodedareas.Andheri Subway was dewatered and opened for traffic by 5.30 am.

Bus services operated by the Brihanmumbai Electric Supply and Transport (BEST) were also diverted on several routes due to waterlogging andthe uprooting of trees causedby heavy rain. While most affected routes were restored by 10.30 am, buses on routes A-224from Santacruz depot to Borivali railway station, 110 from Wadala to Worli, and 117 from Dadar to Wadala depotremained curtailed.

Heavy rain also disrupted suburban railway services on the Trans-Harbour line for nearly an hour,causing significant inconvenience to office-goers and daily commuters travelling between Thane and Navi Mumbai during the early morning peak hours, leading to cascading delays across the network.

The disruption came after soil and ballast beneath the railway tracks caved in between Turbhe and Koparkhairane stations following severe waterlogging in the area. Consequently, train services on the corridor remained suspended for over an hour, from 5.50 am to 7.35 am, affecting connectivity between Thane and Navi Mumbai.

Upon detecting the track issue, Railway authorities immediately initiated safety measures, including crowd management and emergency repair work at the site. According to a Central Railway official, engineering teams were rushed to the affected stretch to stabilise the track bed and restore safe operations. Services resumed shortly after repairs were completed, with normal operations restored by 7.35 am.

The disruption affected 12 services in both directions on the Trans-Harbour line.

Separately, waterlogging was also reported on the tracks at Matunga railway station on the main line, causing a temporary delay of 10-15 minutes to suburban services.
