Sir, that means the intention of the past RM's is questionable, and not the location of there office. May be the past RM's have not taken the "concrete" steps to strengthen the suburban system, but who can guaranty that this move will come with a welcome change. In nut shell I mean that if Mr. Prabhu is really enclined towards the development of the Mumbai Rail system (which I too wish, he really is) then that can be very well done sitting in Delhi itself, where all the other ministries work, rather than shifting the base to any other place....
