I would like to know from members whether there is any limit that has been fixed by the railways on the total number of tickets that can be booked in a train through online mode.Though online ticketing system has been a boon for passengers largely, i feel sometimes passengers booking through online mode have an undue advantage as far as time is concerned. They can book at night after 8pm long after the normal reservation counter closes hence passengers who may not have computer/laptops/access to internet and who only rely on going to the reservation conter are put at a disadvantage.
