Mumbai: It's been a double whammy for Mumbai's commuters on Tuesday.

While the derailment of the Mumbai-Nagpur Doronto Express's derailment early today had a domino effect on Mumbai's local trains plying on the Central Railway route, with services reporting a 20-30 minute delay, the incessant rains have played havoc with the road traffic as well.

With no sign of the downpour ceasing, the city's roads have reported massive water-logging, with vehicular traffic hit badly.

The arterial LJ Road in Mahim, central Mumbai, which connects the suburbs to the island city, has been made one-way following water-logging, with south-bound traffic barred for vehicles. This has had a cascading effect on other key roads that connect the city to the suburbs.

Twenty-four hours of heavy rainfall across Mumbai and Pune has caused massive disruption in road and rail traffic. Both Western and Central Railway services have been cancelled. Western Railway's Twitter handle, put out an alert saying services have been cancelled due to water logging on the tracks. There has also been a signal failure at Bandra following the very heavy rains. As of 20 minutes ago, only the Bandra-Churchgate line was operational. Efforts are on to start traffic on three lines at Bandra as soon as possible by attending to the points, Western Railway tweeted. Rail services will resume with speed restrictions at points and trains will be delayed by 10-15 minutes.
