Train services on the Central Railway's main and harbour lines were disrupted on Sunday morning due to an extended mega block for a bridge girder launch, causing inconvenience to local and long distance travellers. As many as 11 long distance trains that depart from the Chhatrapati Shivaji Maharaj Terminus (CSMT) in south Mumbai have been rescheduled and nine trains which arrive at CSMT have been short-terminated due to the block. There were also reports of a labourer getting injured during the girder launch. The six-hour-long mega block conducted for launching the girder of the under-construction Carnac Bridge was initially scheduled to end at 5.30 am but was delayed. The Central Railway's local train operations were cancelled between Chhatrapati Shivaji Maharaj Terminus and Byculla and between CSMT and Wadala stations on the main and harbour lines due to the mega block.
