The document discusses the computerized Passenger Reservation System (PRS) and Unreserved Ticketing System (UTS) implemented in Indian Railways since 1985. It highlights the technology used, such as optical fiber and microwave communication, as well as the equipment involved in ticket reservation and printing. Additionally, it mentions the Rail Net system that facilitates communication and data transfer across railway divisions.

3. PRS is computerized reservation system for any train
from anywhere in country, launched on 15th November
1985.
The system works both on the optical fiber cable & the
microwave communication at the data rate of 4.8 kbps or 9.6
kbps.

Equipment used in PRS:-
Modem means modulate and demodulate.
We can use modems to log on to micro, mini, main
frame computer for line processing.
It is the process of
converting multi inputs

The end terminal of the system is the station where
tickets are to be printed out. It consists of a company
system with a dot matrix printer

7. It is a computerized system used to issue the tickets for the
unreserved compartments of train .
The system is programmed according to the type of the train.
The system works at the data rate of the 64 kbps .

9. Equipment used in UTS:-

Router
It is the end point of the network from where tickets are to be
printed out .It consists of a monitor, a keyboard and a matrix
printer.
This device is used to interconnect user devices with each other
over 2-wire circuits. The ports available for the interfacing are G-
703, V.35, V.24, V.11.
Router is used to detect the quality samples from different
branches and start sending data from that branch which has
good quality ratio.
The router has 25 input terminals, which means that 25
branches can be connected to the router.

10. It will display the position of trains, signals aspects &point
conditions. The panel contains switches for performing
different operations.
The panel contain 2 seven segment display .
One speaker is also placed for making necessary
appointments.

23. Rail net is an internet for railways.
Important information and data can be transformed from
one division to other division.
Within less time in railways current position of train can
be obtained in PRS.
The connectivity of different reservation take place with
the help of rail net.

25. These 3 aspect which i presented in front
of you are the building block of railway.
Which deals with detail study of signal,
control and communication.
Which in turn help me to develop a
practical view of the subject which I
have learnt in my engineering period.
