TRAIN CONTROL

• Computer Based Interlocking
• Continuous Automatic Train Control (CATC)- It is
  not only a Signaling System.It is an integrated
  train control system.
• Automatic Train Protection (ATP)
• Distance to Go with Track to Train communication
  through Coded AFTC with Cab Signalling
• Automatic Train Supervision (ATS)
• Automatic Route Setting Automatic train
  Regulation
• Centralized control from Operational Control
  Centre
• Automatic Train Operation (ATO)
• For Metro corridor only

• Operation Control Center (OCC).
• Way Side ATP System (at stations).
• On Board ATP equipment (on train).
• Track to Train communication-AFTC(track side)
• Solid State Interlocking (SSI)

PRS SYSTEM

• A countrywide online passenger reservation and
  ticketing system
• Developed and maintained by CRIS( CENTER FOR
  RAILWAY INFORMATION SYSTEMS) .
• Reservation is done via remote location excess.
• All computers are interconnected are Main frame .

UNRESERVED TICKETING SYSTEM-UTS
Indian railways introduced UTS to improve
customer satisfaction, revenue generation,
accounting, and reporting capabilities and reduce
fraud System 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
Tickets can be issued upto 3 days in advance
Indian railways have received the prestigious
computer world honour 2004 for UTS that has
improved customers travelling experience and
provided operational efficiency

FREIGHT OPERATIONS INFORMATION SYSTEM
Instant access to information regarding status
of consignments in transit, for just in time
inventory
Assists in Asset Tracking, Asset Planning
Performance Monitoring , to optimise As set

IVRS SYSTEM

• A state-of-the-art interactive voice response
  system (IVRS) can recognise a customers voice
  and answer queries as well as any person. It can
  enhance our organisations efficiency and make
  our customers happier, unlike conventional
  interactive systems.

COMMUNICATION SYSTEM FOR RAILWAY

• Optical Systems
• Microwave Systems
• Wireless Media
• Radio System
• Telephone Systems
• Passenger Information
• Public Address Systems
• Signal Post Telephones

12
OPTICAL COMMUNICATION SYSTEM
Physical Media

• Copper
• Coaxial Cable - Thick or Thin
• Unshielded Twisted Pair - CAT 3,4,5,5e6
• Optical Fiber
• Multimode
• Singlemode
• Wireless
• Short Range
• Medium Range (Line of Sight)
• Satellite

13
Fiber Media

• Optical fibers use light to send information
  through the optical medium.
• It uses the principal of total internal
  reflection.
• Modulated light transmissions are used to
  transmit the signal.

14
WHAT IS MICROWAVE COMMUNICATION
DEFINITION A communication system that utilizes
the radio frequency band spanning 2 to 60 GHz. As
per IEEE, electromagnetic waves 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

• Very useful in difficult terrain where cable
  laying is not possible.
• Provides mobility to communication nodes.
• Right of way and cable laying costs can be
  reduced.
• Susceptible to rain, atmospheric variations and
  Objects in transmission path.

• RADIO SYSTEM
• Dispatch 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
NETWORK MANAGEMENT SYSTEM
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.
19
PASSENGER RESERVATION SYSTEM Information
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
PUBLIC ADDRESS SYSTEM FOR LOUDSPEAKER Announ
cements 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 the interlocking system
and the Public Address System for automatic
platform announcements.
21
SIGNALPOST TELEPHONES (SPT)
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.

CONCLUSION
Excellence is an art won by training and
habituation. We do not act rightly because we
have virtue or excellence, but we rather have
those because we have acted rightly. We are what
we repeatedly do. Excellence, then, is not an act
but a habit.
After being trained at
the office of DIVISIONAL
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
