UNRESERVED TICKETING SYSTEM-UTS

Tickets can be issued

upto 3 days in advance

Indian railways introducedUTS to improve customer

satisfaction, revenue

generation, accounting, and

reporting capabilities and

reduce fraudSystem is proposed to be

extended progressively on all

zonal railways

The work load involved in

printing , accounting and

issuing tickets to this mega

segment has been a difficult

task

Indian railways have received theprestigious computer world honour2004 for UTS that has improvedcustomers travelling experience andprovided operational efficiency

FREIGHT OPERATIONSINFORMATION SYSTEM

FOIS

An on line real time system

for management and control

of freight traffic

User driven design

and

implementation

Foundations for a

total logistics

system

Instant access toinformation regarding

status of consignments in

transit, for just in time

inventory

Assists in Asset Tracking,

9/25

A state-of-the-art interactive voice

response system (IVRS) can

recognise a customers voice andanswer queries as well as any

person. It can enhance our

organisations efficiency and makeour customers happier, unlike

conventional interactive systems.

Fiber Media

Optical fibers use light to send informationthrough the optical medium.

It uses the principal of total internal reflection.

Modulated light transmissions are used to

transmit the signal.

WHATISMICROWAVECOMMUNICATION

DEFINITIONA communication system that utilizes the radio frequency

band spanning 2 to 60 GHz. As per IEEE, electromagneticwaves between 30 and 300 GHz are called millimeter waves

(MMW) instead of microwaves as their wavelengths are

about 1 to 10mm.

MICROWAVE SYSTEMS Microwave communication is line of

sight radio communication.

Microwave communication can be

analog or digital.

Propagation Types

1.Ground wave propagation

2.Line of sight propagation

3.Sky wave propagation


15/25

WIRELESSMEDIA

Very useful in difficult terrain where cablelaying is not possible.

Provides mobility to communication nodes.

Right of way and cable laying costs can bereduced.

Susceptible to rain, atmospheric variationsand Objects in transmission path.

RADIO SYSTEMDispatch radio systems for railways.

Base station infrastructure and corresponding mobiles and

portable radios can be provided in all frequencies currently used

by the industry.

Each controller in the Traffic Control Room has a radio

dispatch console for voice communication with the train drivers.

Incoming calls are given priorities by the drivers and appear on

the screen according to these priorities. Please ask for detailed

information about radio systems for railways.


18/25

Network Management System (NMS) is a supervision and system dedicated to

operation and maintenance of transmission networks and surrounding

equipment.In the event of failure in a geographically distributed transmission

network, the NMSdetects the alarm signals from all communication subsystems along

the railwayline. Fault identifications are then transmitted to one or more Network

Control Centres (NCC) where maintenance staff can take due action.

NETWORK MANAGEMENT SYSTEM

PASSENGER RESERVATION SYSTEMInformation displays for . Different cabinets and different character

design optimize displays for in-doors well as out-door use.

Displays may be 25" colour monitors, LCD displays with high

intrinsic reliability, LED dot matrix or electromagnetic flap types.

Control an distribution of information to the various platforms are

computerized and can be integrated with train-graph and train control

systems.


20/25

PUBLIC ADDRESS SYSTEMFOR LOUDSPEAKERAnnouncements of train arrivals and departures,delays,etc. will often be integrated in the passenger information

system where preprogrammed messages are stored on

data voice recorders on stations along the railway line.

Unmanned stations will have interface between theinterlocking system and the Public Address System for

automatic platform announcements.


21/25

SPTS are still use in many railway infrastructure companies. Being

part of the safety system.SPT's offer a well proven and reliable system

concept with a unique identification of the calling party.The SPT

system can be operated in both local and central mode.

SIGNALPOST TELEPHONES (SPT)

CONCLUSION

Excellence is an art won by trainingand habituation. We do not act rightlybecause we have virtue or excellence,but we rather have those because we

have acted rightly. We are what werepeatedly do. Excellence, then, is notan act but a habit.

After being trained at the office ofDIVISIONAL RAILWAY MANAGER

I came to know that how Indian Railway employs the

field of Electronics and communication Engineering for

meeting its daily requirement in the segment of

communication
