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 bythe Government of India through the Ministryof Railways.

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

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 m 2 out of

Which 10,858 m2 is covered.

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.

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.

(a) MAIN PARTS OF EXPRESSOR

(b)ADVANTAGES OF EXPRESSOR

• STEPS TAKEN FOR IMPROVEMENT

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.

MAIN PARTS OF TURBO SUPERCHARGER

• GAS INLET CASING

• TURBINE CASING

• INTERMEDIATE CASING

• ROTOR ASSEMBLY

• LUBRICATING SYSTEM

• COOLING SYSTEM

ADVANTAGES OF TURBO SUPERCHARGER

• The thermal efficiency, or fraction of thefuel/air energy that is converted tooutput power, is less with amechanically driven supercharger thanwith a turbocharger, becauseturbochargers are using energy fromthe exhaust gases that would normallybe wasted.

• For this reason, both the economy andthe power of a turbocharged engine areusually better than with superchargers.

• Mechanically driven Superchargers cannotsupply the air at desired volume, as perrequired by the amount of fuel.

METHOD OF LUBRICATION

• Splash lubrication

• Forced feed pump lubrication

• Wick lubrication

EXPRESSOR

• Exhauster + comPRESSOR = EXPRESSOR

• Expresser is a reciprocating type system. It has six cylinders, which arearranged in a ‘W’ type manner i.e., two cylinders are in a vertical positionand four in a V shape.

• It is an air-cooled system with forced feed lubrication. For cooling purposea fan is used which is of a forced draught type, mounted on the crankshaft.

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)

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.

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
