Two passengers travelling on a Central Railway train lost their lives on Monday evening after falling off the train due to overcrowding. According to the General Railway Police (GRP) officials, one was around 25 years old and the other was 30. Both were found unconscious and were taken to Sion Hospital by GRP.Spokesperson of GRP, Ritesh Ahire, said, “Both were taken to the hospital, but were declared dead on arrival. We are in the process of indentifying the deceased.”The rise in number of deaths due to overcrowding has been a cause of concern for the railway department. “In 2015, 806 commuters died after they fell down from overcrowded trains and 1,697 were injured,” said a GRP official.Last year, the death of 21-year-old Bhavesh Nakate between Kopar and Diva had raised questions about safety concerns of commuters using transport system that is operating way beyond its capacity. Nakate's fall, which was recorded by a fellow commuter, had shocked the conscience of the city. In the clip, he could be seen slowly losing grip of the grab rod, pleading for help.The incident had prompted Union Railway Minister Suresh Prabhu to set up a high-level committee to identify the problems faced by rail commuters in Mumbai - about 70 lakh people use the city's local train network daily but nothing has significantly changed since then. "The trains at Dadar, Sion, and Kurla during the evening rush hours are always overcrowded. If you want to check your fitness just go to these stations and board a local in evening,” said Samir Zaveri, a railway activist.Zonal Railway Users' Consultative Committee member, Subhash Gupta, said the suburban railway network was on the verge of collapse. "A local train's capacity is around 1,700 people. But during rush hours, it carries around 5,000 people. You can imagine the plight of the commuters. It's a miracle that people don't die of suffocation inside the compartments,” he added.
