For those who plan to buy unreserved ticket at MAS please be at ticket counter atleast half an hour before especially on Peak times. Of >10 counter, appro 5 will be functioning always and people incl myself have missed trains, due to heavy rush at counter.
If you are coming from Suburban stations and If it is Computerized counter, better get Express/Superfast tickets from there. It is Best alternate to get ticket without hassle of queue..
