Can the number of unauthorised passengers be compared to the number of passengers who to/from suburban stations of Mumbai like KYN/TNA/DR? So no halt will definitely these larger set of passengers and anyways it will never happen that suburban halts are removed
If IR is not able to control pass holders then it is their fault which needs correction, Just for the sake of pass holders you cannot cause inconvenience to the suburban passnengers which include all set of passengers (reserved/unreserved/MST)...
