Booked (online) RR at RMM with respect to destination point (at RMM) 24 Hrs slot (from 22.00 to 22.00 hrs) and my train will arrive at RMM one day before at 11.45 AM [ Train will arrive RMM on 15/10/2016 11.45 AM, and RR booking date/time 16/10/2016 , 22.00 to 17/10/2016 , 22.00]. In RR boarding/ check in rules the railway authority wrote ''late check in is allowed / permissible up to 1 hr after arrival of train'' . Should I report at RMM station authority just after arrival from train (on 15/10/2016) or I report directly just before my check in time (16/10/2016, 22.00Hrs)? Please reply.
