A fight over seats on a Central Railway AC local recently has led to the demand for more such services. With 60 air-conditioned train trips daily, CR Mumbai now runs the highest number of AC local trains in any zone of the Indian Railways. A report in this paper stated that trouble started after a few commuters from Dombivli took a train to Kalyan so that they could block their seats when the train departed for CSMT. This led to an argument between the Kalyan and Dombivli commuters and it quickly devolved into a scuffle.

In the report, a user of the service is quoted as saying that it did not look good that commuters on an AC local should have to fight like this. After the argument and fight, the police came on board and noted down the contact numbers of the commuters. Commuters from Dombivli have been complaining since their much-patronised 7.47 am AC Dombivli CSMT slow local was cancelled after the new Thane-Diva lines were launched.
