INTRODUCTIONABOUT 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.

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

MICROWAVE COMMUNICATION

Radio communication involves :

Microwave + Transmission

Micro + Wave

SmallThe transfer of signals in form of EM waves having

very small wavelength is known as Microwave communication.

10

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

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).

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.

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.

17

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.
