Central Railway motormen have objected to the new services, saying commuters should not blame them if there is no one to drive these new trains.
"The new trains will add pressure on us. As it is we are understaffed and motormen will have to put in extra hours,” motorman's union leader on Central Railway Jayant Nimsudkar said.
"The public and media should not blame us if no one is there to drive these trains."
Nimsudkar said the union conveyed motormen's grievances to the fast track committee in Delhi two days ago and expects results by June 15.
Motormen on Mumbai's suburban trains went on a strike on May 3 to protest against working conditions. At Churchgate, angry commuters broke a ticket-booking window and blamed the railway administration for its failure to gauge the seriousness of the situation, and its inability to ensure smooth running of services.
Home Minister RR Patil intervened and said that the administration will get back to the motormen by June 15.
