PRS UTS Network
With the of computerized passenger reservation
system on Northern Railway in year 1985-86 at
Neimplementation Delhi, a modest beginning was
made which has completely revolutionized the
process of passenger reservation service on
Indian Railways. To begin with the computerized
reservation at Delhi was implemented on small
VAX-750 computer with just 30 terminals. Today it
is a matter of great pride and satisfaction that
highly complex but successful network
ofcomputerized reservation is available at more
than 20 major towns including 4 metros of India,
covering almost 25 of the reservation facility
available on IR.

Other aspects of PRS
Use of satellite data links- The Remote Area
Business Messaging Network (RABMN) of
Dotcommissioned recently may be tried for
linking remote stations where normal BSNL links
may notbe available or are unreliable.(E.g.
North frontier areas from Calcutta PRS) Direct
terminals orteleprinter interfaces might be used
sharing one VSAT link working at 1200 bps,
provided therental and other maintenance costs
do not become prohibitive.
Universal counters for bookingInstant update of

Benefits of PRS
Increased efficiency Optimal utilization of
berths Analysis of traffic pattern for better
overall planningReduction in Revenue losses Real
time availability of Accounting ReportsPlanning
