The advance reservation period (ARP) for booking reserved train tickets will be reduced from existing 120 days to 60 days (excluding the date of journey) from May 1, according to a Railway notification issued today. However, all the bookings done up to April 30 under the existing ARP of 120 days will remain intact. The reduction of advance reservation period to 60 days will be a deterrent for touts who book bulk tickets in advance.
