Madgaon Janshatabdi is a very highly successful and one of the very punctual trains on Konkan stretch with an aggressive schedule. Already it's having perfect RSA with Jalna JS. So, its better not to dwell into altering it on the basis of Past happenings. If the demand is so, then better SR should start a full day time intercity from Mangalore to Mumbai just like SC-VSKP Janmabhoomi express and Mandovi express. It can have a departure slot in between JS and Mandovi while running from Mumbai to Madgaon.
