This project presentation summarizes a communication system for the Rajdhani Express train. It discusses using an IPDSLAM to connect customer digital subscriber lines to a high-speed channel. An exchange and optical fiber cables are used to connect the guard and driver. Public address systems and train indication boards provide announcements and display information for passengers. A data logger records system data, and an IP exchange using Ethernet and optical ports enables packet-based voice, data, and video communication over the network.

3. INTRODUCTION
RAJDHANI EXPRESS
 Rajdhani express is a special type of train.Guard
is the controller of the running train.Train is
controlled by the help of whistle or flag (red as
well as green).
 There are two set systems for communication
between guard and driver:----
(A) VHF- it tends to very high frequency.it’s
range
is 30-300MHZ. Example:-walkie-talkie set 5
hrs 5 watts(the range of walkie-talkie is upto
2km). It is also called line of sight
communication.it means that if driver and guard
are not in same line then communication is not
possible.
(B) POINT-TO-POINT COMMUNICATION-A
point-to- point connection refers to a
communications connection between two
To be

4. INTRODUCTION
A pair of wire between guard and
driver, both have telephone. This
telephone is called magneto
telephone which is very authentic.
MAGNETO TELEPHONE—it has
a handle when handle is rotated
then mechanical energy is
converted into electrical energy by
the help of generator which is
available in this telephone..Ringing
voltage range is—60-70 volts

5. IPDSLAM
 It connects multiple customer digital subscriber line (DSL)
interfaces to a high-speed digital communications channel
using multiplexing techniques.
 Customers connect to the DSLAM through ADSL modems or
DSL routers, which are connected to the PSTN network via
typical unshielded twisted pair telephone lines. Each DSLAM
has multiple aggregation cards, and each such card can
have multiple ports to which the customers lines are
connected.

6. EXCHANGE
 It is an Israel system. It is a
1200 line exchange which is
called SPC or Stored
Program Control. It is also
called ISDN type exchange.
 Technical Description of
System:-The Coral Flexi-
Com digital communications
switching system employs
the latest advancements in
telecommunications
technology.

7. OPTICAL FIBER CABLE
 An optical fiber cable is a cable containing
one or more optical fiber. The optical fiber
elements are typically individually coated with
plastic layers and contained in a protective
tube suitable for the environment where the
cable will be deployed.
 Optical Fiber communication:-Glass fibers
carrying information at frequencies of visible
light spectrum.
Advantage:- 1. No induction effect.
2. Low transmission loss.
3. High bandwidth.
4. Speed of communication
is more.
5. Less weather effect.
6. Safety and security is
more.
Disadvantage:- 1. Requirement of high
skilled staff.

8. PUBLIC ADDRESS(PA) AND TRAIN INDICATION BOARD(TIB)
ANNOUNCEMENT SYSTEM:-
The PA closely integrates the audio and
visual functions for conveying the desired
information to passengers. The system
generally consists of:-
A. Visual Equipment:-Visual equipment,
consisting of saloon displays and head
code displays, conveys journey-related
information for the convenience of
passengers.
B. Audio equipment: Audio equipment are
used for automatic and manual
announcements to passengers travelling in
the train.
TIB: -(TRAIN INDICATION BOARD)
Train Indication Boards are provided at
entrance / exit and other public utility
places of railway station premises. These
are the display devices which gives the
information regarding Train name and no.

9. DATA LOGGER
 A data logger (also datalogger or data
recorder) is an electronic device that records
data over time or in relation to location either
with a built in instrument or sensor or via
external instruments and sensors.
 Data loggers vary between general purpose
types for a range of measurement applications
to very specific devices for measuring in one
environment or application type only.

10. IP EXCHANGE
 It tends to internetwork packet exchange.
 Packet based communication, enabling use
of common infrastructure for data, voice
and video communication.
It has two types of switches:-- (a)
Ethernet port
(b) optical
port
 Upto 100 meters Ethernet port is used and
more than 100 meters transmission is
lossed so optical port is used.
 Power over Ethernet is used for giving
power to the IP devices.
