Unpopular Opinion but if they are asking for a suburban system like Bombay, they are already shortchanging themselves. Mumbai's suburban trains are dangerous, over crowded and a relic of the past, I had argue. If anything, they should demand something like RapidX metro that is being used to connect Delhi to Meerut. That is more modern, convenient, air conditioned and did I mention, no chance of anyone being killed directly or indirectly unlike the suburban mess than Mumbai is.
