RAILWAYS-A Brief HistoryBy 1849, The Indian Peninsular Railway took the work.

By December 1851, the first Steam Loco was invented.

By 1946 all 42 rail systems taken over by govt. to make a

World’s largest public sector enterprise with 1.5 million

employees.

Indian Railways is serving more than 100 crore people

continuously since April16,1853 when the first train was run

NORTHERN RAILWAYThe Northern Railways is one of the 16 zones of the Indian

Railways.The railway zone was created on 14 April 1952 Its headquarters is in Delhi at New Delhi Railway Station.

Northern Railways is one of nine old zones of Indian Railways and also the biggest in terms of network having 6807 kilometre route.

It covers the states of Jammu and Kashmir, Punjab, Haryana, Himachal Pradesh, Uttarakhand and Uttar Pradesh and the Union territories of Delhi and Chandigarh.

HISTORY OF LOCOMOTIVE WORKSHOP, CHARBAGHThe locomotive workshop at Charbagh, Lucknow, was

established in the year 1867 under Oudh & Rohilkhand Railways for overhauling of steam locomotives. After independence this workshop came under Northern Railway.

The activities in course of time have changed from POH of steam locomotives to now POH/ IOH/ of Diesel locomotives (WDM2B, WDM2A, WDM2C,WDP1 , WDP2, WDP3, WDG2, WDM3 & WDG3), Electric locomotives (WAM4, WAG5, & WAG7), DMUs.

What Is GOVERNOR?A device used to measure and regulate the speed

of an engine. Woodward governor is commonly used on board .A hydraulic amplifier amplifies the governor’s

signal to the fuel pump.The hydraulic pressure for the amplifier is

delivered by the camshaft lubricating oil system.

The microcontroller based governor consists of a control unit mounted in the drive cab and an actuator unit mounted on the engine.

How it looks like…..

1. FUNCTIONTo maintain the engine speed at the desire value by controlling the fuel injection.

At the time of low pressure of lubrication oil, it stops the engine.

It controls the main generator to protect against overload and under load.

At the time of starting, lubrication oil pressure of low, so it prevents the engine from stopping upto 40 sec.

It shuts downs the engine when water level is low.

REMARKS ON FAILURES AND IRREGULAR OPERATION Parts of governor jamming Pump or non-return valve in governor defective The governor does not function properlyThe governor does not operate the regulating

linkageThe governor does not respond to load changesThe governor has just undergone repairsThe governor has trippedThe governor is blockedThe governor is cold

The governor is defective The governor is gear-drivenThe governor is huntingThe governor is incorrectly adjusted The governor is warmThe governor operates irregularlyThe governor has picked up errorsThe governor speed setting incorrectly

adjustedThe governor sticks
