Communication System in Railway 2

Introduction

• The first railway on Indian sub-continent ran over a stretch

of 21 miles from Bombay to Thane.

• Indian Railways is divided into zones, which are further

sub-divided into divisions.

• Each zonal railway is made up of a certain number of

divisions, each having a divisional headquarters. There are a

total of sixty-seven divisions.

• Railway communication provides uninterrupted motion of

trains. Due to faster means of communication there is

increase in the efficiency and greater control.

Communication section in Lucknow Electrification office


Synchronous Transport Module• STM 1 = 16 E1 = 512 voice Channels

• STM 4 = 4 X 63 E1 = 252 E1 = 2048 voice Channels

• STM 16 = 16 X 63 E1 =1008 E1 = 8192 voice Channels

• 1 E1 =2 MB line = 32 Channels

• E1 Engineering Order wire (EOW). It can be used to transmitspeech signals

• 32 Channels = 30 voice Channels + 1 Signaling channel

+ 1 synchronization channel



IRIS (Integrated

Risk Information

System)

IRIS( Integrated risk information system)

Card Description1) Main Controller Card (MCC) – It is the heart of ISDN

exchange. It can support 8192 cards.

Functions of MCC –

• Used to control other cards.

• External music facility with 16 minutes music recording

• DTMF (Dual tone multi frequency) generator and receiver

• All tones (Dial tone , ring back tone , busy tone etc.)

2) Peripheral board controller card (PBC) –It is used for the

communication between main shelf and peripheral shelves.


3) Featured Line Card (FLC) - It is used for giving 32 port

(analog lines). Line operating voltage is 48 volt.

4)Digital Corner Card (DCC) - It is 16 port/8 port card used to

connect key phones.

5) Feature Trunk Card (FTC) – It is 24 port card used to

terminate analog trunk lines.

6) E1 Card (CEPT/PRI(30)- This card supports 30 digital

trunks.


Types of controls1) Section Control - This signal is used to control the

movement of train. It is provided by ASM (Assistant StationMaster) office at every station.

2) Deputy Control – This signal is used for the control of stockcars.

3) Emergency Control – This signal is used in case ofemergency like accidents, derailment.

4) Traction Power Control (TPC) – This signal is used tocontrol the OHE (Over Head Equipment) power supply(25KVA).


5) Traction Loco Control (TLC) – This signal is used to control

the movement of loco (engine), which is send for inspection.

6) S & T Control – Signal and telecommunication control is used

for communication between stations.

7) Engineering Control – This control is used by engineers.

8) Remote Control – this is used to control the switching the

OHE power supply by remote.

Optical Fiber

• Optical fiber consists of a core and a cladding layer, selected

for total internal reflection due to the difference in

the refractive index between the two.


• In practical fibers, the cladding is usually coated with alayer of acrylate polymer or polyimide. This coatingprotects the fiber from damage but does not contribute toits optical waveguide properties.

• The jacketed fiber is generally enclosed, with a bundle offlexible fibrous polymer strength members like aramid(e.g. Kevlar), in a lightweight plastic cover to form asimple cable.

• Each end of the cable may be terminated with aspecialized optical fiber connector to allow it to beeasily connected and disconnected from transmitting andreceiving equipment


• Jacket material –

Polyvinyl chloride (PVC)

Polyethylene (PE)

Polyurethane (PUR)

Polyamide (PA)

• There are two main types of material used for optical fibers.

These are glass and plastic.

• They offer widely different characteristics and therefore

fibers made from the two different substances find uses in

very different application.


To connect broken OFC

• Strip the wire.

• After stripping take MX

cleaver which cuts the

fiber at angle 90.

• Clean fiber with alcohol

and tissue.

• Take fiber to splice

machine.

• Make sure both the fiber

are near to the electrode

of the machine.

• Losses less than 0.1 dB .Communication System in Railway 18

Conclusion

Role of the Signaling & Telecommunications Department

• efficiency and greater control.

• Safety in train operations

• Punctuality of running of trains

• Optimum utilization of line capacity

• Safe and efficient operation of trains

• Administrative voice and data circuits

• Passenger Reservation System (PRS)

• Unreserved Ticketing System (UTS)
