INTRODUCTION 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 locomotives

HISTORY 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 homing162 Diesel Locos

it serves a large number of Mails /Express trains which across the length & breadth of the country casting to goods operation

SHED LAYOUT

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.

FUEL SECTION

The total oil expenditure of 4700 crore rupees/year is a big amount so this is one of the most concentrating fields for the government.

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 charging is used to increase the amount of air pushed into each cylinder.

TURBO SUPER CHARGER

The turbo charger is driven by exhaust gas from the engine

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

Turbo charging gives a 50% increase in engine 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

EXPRESSOR

• 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 brake system.

TESTS CONDUCTING ON CYLINDER ON CYLINDER HEAD HYDRAULIC TESTING

In this testing the head is testing for any type of water leakage from the water jackets made for cooling system

CYLINDER HEAD SECTION

Different parts of the cylinder head•Valve guide•Spring seat•Equalizing yoke guide•Push rod•Valve seat insert•Nozzle cooling sleeve

SPEEDOMETER SECTION

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 easier.

The control panel of WDM2 has:-•Two vacuum gauges•Two vacuum duplex•Two main reservoir duplex•Two air flow gauge•Central air gauge
