2. I, student “Chandravati Group Of Institution ,Bharatpur
“would like to pay my heart felt thanks to the Indian Railway
for providing an immense knowledge and co-operation. I
would like to express my gratitude to “ Mr. Anamol kumar ”
(j.en) DRM KOTA for their corperation and
Guidance during the training.

3. Indian Railway is the world’s fourth largest commercial, by
number of employees with over 1.4 million employees.
Railways were first introduced in India in 1853. Indian
Railways operates both long distance and suburban rail
systems on a multi-gauge network of board meter and narrow
gauges.
From 20th December 2010, the railways had developed a 5 digit
numbering system. This need is required because IR runs
10,000 trains daily

4. After many decades of satisfactory performance, the steam
engines were to give way to more modern locomotives.
The year 1881 saw the birth of the first electric Railway run
by a German Engineer Werner Van Siemens using both the
rails to carry the current. Finding this a little too dangerous,
Siemens soon adopted the overhead electric wires.
Electric locomotives today raun on Rail roads in many
countries.

LINES
PANTOGRAPH

15.  For step down the 25kv
to traction motor
terminal voltage.

16.  NO COMMUTATOR IS AVAILABLE.
 REGENERATIVE BRACKING IS TO DIFFICULT .
 FINE CONTROL OF SPEED & TORQUE.

20.  Substation should be located
near at traction lines.
 Near the relay staff room.
 Sufficient land area
 Suitability of standard
equipments.
 Graounding
 Possibility of expansion
 Ease of maintenance
 Reliability and security

21. To Change voltage from one level to another.
To Regulate voltage to compensate for system voltage
changes.
To Switch transmission and distribution circuits into and
out of the grid system.
To Measure electric power quantity flowing in the circuits.
To Connect communication signals to the circuits.
To Eliminate lightning and other electrical surges from the
system.
To Connect electric generation plants to the system.
To Make interconnections between the electric systems of
more than one utility.

etc.in coach

26.  End on generation
 Self-generation

27.  Ratings -
250KVA,750V

30.  For small branch slow
trains.
 generation is at 415 V, 3
phase, is step downed at
110v 3phase,

31.  Working voltages
110v both Ac/Dc

32.  In platform lightning two type sensors are used:-
1) Lightning sensor
2) Train scheduler sensors

33.  1 All the lightning system is replace by sensor base
lightning system.
 2 solar panels lightning system are used.
 3 All bulbs are replaced by CFL.
 4.Now a days we are using led light in place of CFL.
