The Harbour line on the Central railway faced two disruptions in four hours on Monday morning on the first day of October, leading to the collapse of peak hour services. Officials said a crack was discovered in the track between Belapur and Seawoods station around 9.30am, which led to the delay of three local trains.

Even after the crack was fixed around 9.54am, trains continued to run slow thanks to the bunching effect. As these trains were coming back on the track, the downline services were affected after a local train bound for Panvel developed a snag around 11.30am near Kharghar.
