I have booked two SL tickets from Suratkal to Kengeri by Train No:16524 with boarding as Kabaka Puttur (this was done as quota was available for journey starting before Kabaka Puttur). In case I want to commence my journey from Suratkal itself, am I permitted to do so as the ticket is from Suratkal to Kengeri or I have to buy general ticket and travel in general compartment till Kabaka?
