INTRODUCTION
• Indian Railway has the world's fourth largest railway network .
• Indian Railway’s First train in Indian Railway between Mumbai to Thana on
16th April 1853.
• Indian Railway is divided into 17 zones, which are further sub-
divided into
67 divisions.
• Indian Railway is one of the world's largest commercial or utility employers,
with
more than 1.6 million employees and there is no strike since last 30 years.
North Western Railway
• It came into existence on 1st oct. 2002.
• It is one of the sixteen railway zones in India.
LOCOMOTIVES:
• Steam Locomotive
• Diesel Locomotive
• Electric Locomotive
Electric Locomotive
Training Departments
1.Train lighting
2. Air-Conditioning
Classification of Coaches(Based On Generation)
BG COACHES
End On Generation
Spilt Type Under Slung
Roof Mount Package Unit
(RMPU)
Self Generating
AC Coaches
Split TypeUnder Slung
RMPU with 25 KVA
inverter
Non AC Coaches
Mid-On Generation
Train Lighting
Systems used in the Train Lighting are:
1. End-On generation
2. Self-Generation
3. Mid-on Generation
End-On generation• Express Trains Having Heavy Load Use EOG Coaches.
• The Power Is Supplied At 3 Φ, 750 V, Which Is Stepped Down In
Individual Coach To 3 Φ, 415 V, For Supplying Various Loads Like RMPU,
Etc.
• The 110 V Ac Supply For Lights And Fans Is Obtained By Further Stepping
Down The 415 V Supply.
• A 24 V Battery Is Used For Supplying A Few Emergency Lights Provided In
The Coach.
End-On generation
Fig: End on generation
End-On generation
• Generator Car
• Two generator cars present usually
• Consists of two generators in each car
• For low value of load only one is in working
• Both can be operated simultaneously
Self-Generating System
• The power supply arrangement of SG coach has under slung alternator,
which is driven by the running axles of the coach with the belt of the
coach.
• The voltage of the alternator which varies with the speed of the train is
regulated with the help of RRU and converted to 110 v DC and is used for
charging the battery.
Self-Generating System
Fig: self generating system
Mid-on–generation• The MOG system was adopted by IR for slow moving passenger trains
which
have very low generation to non-generation ratio.
• These trains had one power car in the middle of the train, which fed power
supply to the coaches at either side of power car.
• The power car coach had two DA set of 30 KVA each out of which one was
used as standby. The power car coach also had one 3 Φ, 30 kVA step down
transformer of 415/110 v. The 110 v AC supplied to the coaches through
couplers.
Air Conditioner
Major Parts of A/C system
• Compressor
Condenser Unit
Gauge Panel
Air Duct
Compressor
• Compress the vapour of refrigerant
• pressure is about10-15kg/cm2
• raises the temperature of refrigerant vapour
• Extracts heat absorbed by refrigerant vapour
• Consists of heat exchanger
• Fitted with a blower
Condenser• It is a device or unit used to condense a substance from its gaseous to its l iquid state, by cooling it .
• Condensers are used in refrigerators, air conditioning, Industrial chemical processes such as distillation, steam power plants.
Gauge PanelIt consists of pressure gauges & pressure cut-outs to protect the compressor against high pressure & low pressure.
1. High pressure cut-out
2. Low pressure cut-out
3. Oil pressure cut-out
Air Duct
• They are used in heating, ventilation & air
conditioning to deliver & remove air.
• Ducts commonly also deliver ventilation air as
part of the supply air.
• Three types of air ducts are there:-
A) Fresh (inlet) air duct
B) Main air duct
C) Return air duct
Conclusion• During my training at north western railway Jaipur , I learnt about basics of generation of electricity in train itself and uses of electricity in railway.
• This training helped me out to understand the concept of air conditioning system & train lighting system which enhance my knowledge about the AC & train lighting system.
• In this time period I gained a lot of knowledge, experience and ability to work with team.
