Brief introduction

The Passenger Reservation complex located at Secunderabad was built in the year1989, PRS houses important servers where the disaster recovery servers areinstalled for replicating of online information of the entire ticketing system onIndian Railway.

The PRS Application CONCERT (Country-wide Network of Computerized EnhancedReservation and Ticketing) is the world’s largest online reservation application,developed and maintained by CRIS.

PRS provides reservation services to nearly 1.5 to 2.2 million passengers a day onover 2500 trains running throughout the country.

The system currently operates from 5 Data centres located at New Delhi, Kolkata, Mumbai, Chennai & Secunderabad.

The server clusters are connected together by a core network that enables universal terminals across country, through which the travelling public can reserve a berth on any train, between any pair of station for any date and class
