3. INTRODUCTION
ABOUT INDIAN RAILWAY
• It is a Rail Transport industry.
• It is founded on 16th April
1853.
• It’s headquarter is in new
Delhi, India.
• 1.307 billion employees are
working in Indian railway till
2013.

4. RAILNET
• Rail net is an internet for railways. The rail net
is a railway open system for quick data
transmission and data using resources at
different places. it is purely under railway and
information and data are collected at the
headquarter through different divisions and
unit consists of main switch ,web server ,
switch, hub, router, modem, LAN and WAN
extenders and pc’s that are considered as the
nodes

10. MICROWAVE COMMUNICATION
Radio communication involves :
Microwave + Transmission
Micro + Wave
Small
The transfer of signals in form of EM waves having
very small wavelength is known as Microwave
communication.

11. EM WAVE
THE PROPERTIES OF EM WAVES ARE AS
FOLLOWING:-
• They travel with the velocity of light they can
propagate in free space and vacuum.
• Their behaviour corresponds to light waves.
11

12. OPTICAL FIBER
Optical fiber are used most often as a means to
transmit light between the two ends of the fiber and
find wide usage in fiber-optic communications,
where they permit transmission over longer distances
and at higher bandwidths (data rates) than wire
cables. It works on the principle of TIR (Total
Internal Reflection).

15. SYSTEM OF SIGNALLING
• Railway signalling is a system used to control railway
traffic safely, essentially to prevent trains from collision.
Being guided by fixed rails, trains are uniquely
susceptible to collision; furthermore, trains cannot stop
quickly, and frequently operate at speeds that do not
enable them to stop within sighting distance of the driver.

17. PASSENGER RESERVATION
SYSTEM (PRS)
Introduction
• The Passenger Reservation System (PRS) is computerized
reservation system for any train from anywhere in country. This system
has made the train journey quite comfortable.
• When PRS system was not developed a station could give the
reservation to the customer.
• Those train which get started from their station but after PRS get
installed the customer can get information about any train running in
India.

18. CONCLUSION
• This summer training enhances our technical knowledge. We got to
know about different technologies, kits and projects which are use in
railway.
• We got to know how the kits and components are manufactures
which we are using and what is the basic concept behind them.
• We learned how the team work is done and how work is carried out
in industries. This will definitely help us in future and in our
placements also. It was a very interesting and knowledgeable training
and it was a great opportunity to be a part of it.
