I want to give following information to travellers of train 16524 karwar yeshvanthpur express.Now railways have changed boarding point rule.from 1st oct 2013.Now if there is no seat from mangalore to bangalore you can book a ticket from Udupi to Bangalore and change your boarding point to mangalore. You have to spend only rs 25 extra.(If you go through seat availbility you always find mangalore bangalore quota full and quota between udupi bangalore is always available in hundreds). For reference you can read railway commercial no 47 2013
