Its impossible... it is a dedicated train to Mangaluru from Mumbai it is one of the important trains for coastal karnataka... This train have a great place in the hearts of coastal people... Since it is a hit train since its inaugration in 1998 so no need to extend also one more fact is that if this train gets extended to ERS then KUDA,BTJL,UD, MRDW will loose GN quota & get PQ quota
