Ranjeet, one of the conditions for break journey, stipulates that " Intention to break journey is to be advised at the time of original booking and not after obtaining reservation". So in this case break journey at KARWAR is PERMISSIBLE ONLY if the original ticket had been booked from Thane to Mookambika Road with RESERVATION UPTO KARWAR by 12133 and not in the instant case where reservation has been made upto MOOKAMBIKA ROAD.
