Local train services on the Central Railway's harbour line were restored by 3 am on Wednesday, more than 15 hours after Mumbai's lifeline was halted due to the submergence of tracks following heavy rains, officials said.

All public transport services in Mumbai, including local trains, resumed normal operations on Wednesday morning, a day after the torrential rains crippled normal life, they said.

According to Swanil Nila, chief public relations officer of the Central Railway, the harbour line services were fully restored after the water receded from the tracks at 3 am. The services were suspended at around 11.15 am on Tuesday.
