Mumbai: Mumbai’s suburban railway system came to a halt for more than six hours, first due to a technical snag and later due to protests by angry commuters.

Around 6.30am, a train bound for Chhatrapati Shivaji Terminus (CST) broke down at Thakurli station near Kalyan. It took more than three hours for railway authorities to carry out repairs.

As motormen of suburban railway network were targeted, they refused to ply the trains, which disrupted service on the harbour line.

The Mumbai metropolitan region is served by four lines; while three lines are operated by central railway, one line is operated by western railway and together they carry around 7.5 million passengers daily.

The three lines operated by central railway are main line or central line between CST and Karjat and Kasara, harbour line between CST and Panvel and Trans Harbour line between Thane and Panvel. The western line connects Churchgate in south Mumbai to Dahanu in North.

The central line of suburban railway network broke down several times last year.

Speaking with reporters, chief minister Devendra Fadnavis said, “I have spoken with railway minister Suresh Prabhu about constant technical snags on central railway and hardships it causes to commuters and he has assured to take urgent steps to resolve the issue."
