Indian Railways has one of the largest and busiest
rail networks in the world, transporting over 18
million passengers and more than 2 million tones
of freight daily. It is the world's largest commercial
or utility employer, with more than 1.4 million
employees. The railways traverse the length and
breadth of the country, covering 6,909 stations
over a total route length of more than 63,327
kilometers (39,350 mi). 50,000 coaches and 8,000
First railway system in India was proposed in
1832 in Madras.
The first train in India was not a passenger
train and was operational on 1851-12-22.
A few years later, on 1853-04-16,the first
passenger train between Bori Bunder, Bombay
and Thana covering a distance of 34 km (21
miles) was inaugurated.
almost six years later, on March 3, 1859, the
first Railway Line in North India was laid
between Allahabad and Kanpur.
DIESEL SHED LUCKNOW
lucknow is one such premier shed in Northern Railways homing
162 Diesel Locos
it serves a large number of Mails /Express trains which
across the length & breadth of the country casting to
The shed has a total berthing capacity for 17 locomotives
under 4 covered bays. The main bays are:•The subassemblies section
•The heavy repair and bogie section(3 berths for heavy
repairs & 2 lifting points)
•Mail running repair bay(6 berths).
•Goods and out of course running repair bay. There was
one old steam shed. This shed had a capacity for berthing
4 locomotives. This shed was used for light repairs only.
Now a days, a new construction is being on for new locos
of make WDP4 locomotives.
The total oil expenditure of 4700 crore rupees/year is a big
amount so this is one of the most concentrating fields for the
Before unloading following thing are checked.
• The oil is tested by lube oil lab.
• The temperature at time of unloading and by
multiplying by the temp. with the Correction
factor, the exact volume is calculated.
• The moisture in the oil is checked.
TURBO SUPER CHARGER
Turbo charging is used to increase the
amount of air pushed into each cylinder.
The turbo charger is driven by exhaust
gas from the engine
Turbo charging gives a 50% increase in
The main advantage of the turbo charger is that it
gives more power with no increase in fuel costs
because it uses exhaust drive power
The amount of fuel which can be burnt depends on
the amount of air available in the cylinder.
The main function of exhauster unit is to create
vacuum 22” in train pipe
• Air from vacuum train pipe is drawn into the
exhauster cylinders through the inlet valves
during its suction stroke and that air is thrown
out to atmosphere during compression stroke
through discharge valves
• the air at high pressure and discharge it in
main reservoir of locomotive for the use of
CYLINDER HEAD SECTION
TESTS CONDUCTING ON CYLINDER ON CYLINDER HEAD
In this testing the head is testing for any type of water
leakage from the water jackets made for cooling system
Different parts of the cylinder head
•Equalizing yoke guide
•Valve seat insert
•Nozzle cooling sleeve
The memory cards records the data of speed at every
moment when the loco runs on the line. This
information makes the maintenance process much
The control panel of WDM2 has:•Two vacuum gauges
•Two vacuum duplex
•Two main reservoir duplex
•Two air flow gauge
•Central air gauge
