1-1.5 hrs. However, in ideal circumstances its a less than 45 mins trip. but traffic can easily double ur time. Traffic can be a menace from 7 in the morning to 12 in the night, so leave accordingly. Since trains are packed usually round the clock (i guess gone are the days when afternoons one could find a seat) its not advisable for a person with luggage or rather even expensive or imp, stuff. :cool2:
