Thanks. Yes when I tried to select a different boarding point while online booking. But do you know if I can change the boarding station to a different quota station. I went to a railway station in Bangalore and he told I will have to talk to chief reservation office of main railway station in the city and also he told since my new boarding station does not fall in same quota as old one change of boarding station is not gauranteed. I am kind of confused and scared at the same time as I booked the ticket thinking I would be able to change the boarding for sure.
