PRS – PASSENGER RESERVATION SYSTEM
About PRS

Reserved travel by Indian Railways is facilitated by the Passenger Reservation System (PRS). PRS provides reservation services to nearly 1.5 to 2.2 million passengers a day on over 2500 trains running throughout the country. The PRS Application CONCERT (Country-wide Network of Computerized Enhanced Reservation and Ticketing) is the world’s largest online reservation application, developed and maintained by CRIS. The system currently operates from 5 Data centers. 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.

PRS web site was awarded Web Ratna Platinum Icon Award in year 2009 under Citizen Centric Service category. PRS application has been awarded by Computer Society of India for best IT usage in the year 1999. If you have any further questions or suggestions email us at prs@cris.org.in.

 

Reservation System

The PRS is available at over 8000 counters in more than 2380 locations throughout the country, including all major stations, and important non-railhead locations such as tourist centers and district headquarters. The PRS services are available to passengers for 23 hours in a day. Passengers can reserve a berth for any train 90 days in advance. In addition to the railway counters, multiple delivery channels have been provided to Rail passengers to access the PRS services. Enquiry services through Internet were launched in year 2000. Touch screen, IVRS and Display boards are enabled at major booking location for details on train accommodation availability. I- Ticketing and E-ticketing and through Internet was launched in year 2002 and 2005 respectively. Booking through Post offices was launched in year 2007.Enquiry services through 139 were launched in year 2007. PRS ticketing through Mobile VAN (Mushkil Assan) was launched in 2009.

Automating Ticket Checking

To improve the transparency in seat allocation after charting and increase the berth utilization, PRS is in the process of automating the operations of TTE. It is aimed that the passenger attendance is marked by the TTE on a Hand Held Device instead of a paper chart and the berths, vacant on account of not turned up passengers are transferred to a central database. These berths can be utilized by TTE for allocation to RAC/WL passengers or to WL passengers/ with current Ticket intending to board the Train from next stopping station. This will also speed up the refund process as the data regarding not turned up passengers will be directly transferred to Refund System. Hand Held Terminals (HHTs) are already functioning in 12 pair of trains. Indian Railways plans to extend this facility to another 70 pair of Rajdhani and Shatabdi Trains

CONCERT Architecture

CONCERT architecture is based on the state of the art technology using 3-tier client-server distributed transaction processing paradigm. The system has distributed architecture with 5 server clusters placed in server centers in five cities: New Delhi, Mumbai, Kolkata, Chennai and Secunderabad. The server clusters are connected together by a core network based on a mesh of 02×02 Mbps leased lines. It is an on-line client server application developed in ‘C’ on OVMS using RTR (Reliable Transaction Router) as middleware. It is currently hosted on state of art converged infrastructure (Itanium blade servers).

Server Blade servers having 64-Bit Itanium 9340 Processor
Operating System Open VMS 8.4
Database In-house CRIS proprietary
Middleware HP Reliable Transaction Router (RTR)
Frontend DEC Forms, C and FORTRAN as development tools
Communication Systems CISCO routers using 2Mbps DOT lines
Network Topology Mesh Topology

Hand Held Terminals for Ticket Checking

The application is developed in-house based on IBM Lotus Expeditor technology. The mobile technologies used are Lotus mobile connect version 6.1.1 for VPN, Lotus expeditor synch server (version 6.2) and DB2E on mobile devices. IBM Tivoli directory server LDAP (version 6.0) is being used for user authentication. The servers are Xeon (Dell power edge 2950) with OS - RHEL 4 update 4. The RDBMS is DB2 version 9.1.5 and Application server - IBM WAS 7.0.0.9.
