So much focus on design, architecture!? Simultaneously, IR should develop terminals and introduce token / pass / ticket entry systems as in other station of world standards often envisaged in India. Entire stations should be designed to prevent trespassing instead of recreating the stations once in a decade or so. Even Kenya has such system, of course because of Chinese funding and development of the newly constructed Nairobi - Mombasa line. For a country like India, it will be financally viable.
Delhi Metro is a solid classic example of how India abides by the rule and travel since the start of millennium. Everything is possible with proper utilisation of resources.
