2. INTRODUCTION TO RAILWAY
• Railways were first introduced to India in 1853
from Bombay to Thane.
• In 1951 the systems were nationalised as one
unit, the Indian Railways, becoming one of the
largest networks in the world.
• Indian Railways is an Indian state-owned
enterprise, owned and operated by
the Government of India through the Ministry
of Railways.
3. ABOUT DIESEL SHED
• It is a place where repair and maintenance work of diesel locomotives Is
carried out so as to increases its life and efficiency and to reduce line
failures to a minimum extent.
• Diesel locomotives are classified on the basis of the track Gauge:-
1) Broad Gauge
2) Meter gauge
3) Narrow gauge
4. HISTORY
• Diesel Shed ,Tughlakabad was established in the year 1970 with a
planned holding of 75 locomotives and initial holding of 26 WDM2
locomotives.
• Because of its geographical location and being in the capital, it serves a
large number of Mails /Express trains which across the length & breadth of
the country casting to goods operation.
• Diesel Shed, Tughlakabad is spread over an area of 1,10,000 m2 out of
Which 10,858 m2 is covered.
5. DIESEL SHED TUGHLAKABAD PROFILE
• Tughlakabad is one such premier shed in Northern Railways homing
162 Diesel Locos.
• Shed is maintain a mail link of 122 locos, which is highest for any shed on
Indian railways.
6. DIESEL TRAINING CENTRE
• Diesel training centre at Tughlakabad was set in 1975 in premises of diesel
shed, Tughlakabad northern railway with a view to train diesel running staff
as well as diesel maintenance to improve overall efficiency of railway
workers quality by upgrading the knowledge of railway workmen by
starting few courses.

(b)ADVANTAGES OF EXPRESSOR
• STEPS TAKEN FOR IMPROVEMENT
8. TURBO SUPERCHARGER
• Supercharging is done by the Supercharger. Now the Supercharger can be
powered mechanically by belt, gear and shaft, or chain-drive from the
engine's crankshaft e.g. Compressor.
• It can also be driven by a gas turbine powered by the exhaust gases from
the engine. Turbine-driven Superchargers are correctly referred to as
TurboSuperchargers.
9. MAIN PARTS OF TURBO SUPERCHARGER
• GAS INLET CASING
• TURBINE CASING
• INTERMEDIATE CASING
• ROTOR ASSEMBLY
• LUBRICATING SYSTEM
• COOLING SYSTEM
10. ADVANTAGES OF TURBO SUPERCHARGER
• The thermal efficiency, or fraction of the
fuel/air energy that is converted to
output power, is less with a
mechanically driven supercharger than
with a turbocharger, because
turbochargers are using energy from
the exhaust gases that would normally
be wasted.
• For this reason, both the economy and
the power of a turbocharged engine are
usually better than with superchargers.
• Mechanically driven Superchargers cannot
supply the air at desired volume, as per
required by the amount of fuel.
12. EXPRESSOR
• Exhauster + comPRESSOR = EXPRESSOR
• Expresser is a reciprocating type system. It has six cylinders, which are
arranged in a ‘W’ type manner i.e., two cylinders are in a vertical position
and four in a V shape.
• It is an air-cooled system with forced feed lubrication. For cooling purpose
a fan is used which is of a forced draught type, mounted on the crankshaft.
13. MAIN PARTS OF EXPRESSOR
• CRANK CASE
• CYLINDER AND CYLINDER HEAD
• INLET AND DISCHARGE VALVES
• PISTON AND CONNECTING ROD
• INTER COOLER
• SAFETY VALVE
TRC 306 X 460 (6CD 3UC)
14. ADVANTAGES OF EXPRESSOR
• Reduced size and weight for added mobility
• Fiberglass enclosure for scratch resistance and rust proof
• Individual heavy duty air cleaner for both compressor and
engine
• Strong and light weight unibody construction.
• Electronic powder - coat paint for unsurpassed durability.
15. STEP TAKEN FOR IMPROVEMENT
• ASSEMBLY WISE TREND ANALYSIS OF
FAILURES
• RESPONSIBILITY WISE ANALYSIS OF
FAILURES
• SENSITISING THE STAFF TO ACTUAL
PERFORMANCE
• TRAINING
• ENHANCING THE SAFETY FEATURES
OF THE LOCOMOTIVE
