As it happened during peak commuting hours, passengers were angry as they were caught unprepared and had arranged no alternative transport mode.
Local train services on the western line - which starts at Churchgate in the city's business district and follows the west coast north for about 124 kilometers to Dahanu Road (towards Ahmedabad) - were also affected.
Mail and express trains, however, were allowed to pass.
The cause of this block is yet to be determined.
Further details from Western Railway and the concerned authorities are awaited.
