This technical report summarizes a visit to an electric locomotive workshop. It describes the key internal parts of an electric locomotive such as the transformer, rectifier, armature converter and traction motors. It provides photos and explanations of the control desk, instrumentation, electrical equipment and auxiliary systems used for cooling. Advantages of electric locomotives are highlighted like reduced emissions, maintenance and noise compared to diesel. The report concludes the workshop helped learn about electric locomotives used extensively in Indian railways.

INTRODUCTION Locomotives in india consist of electric and diesel locomotives. Locomotives are also called locos or engines. An electric locomotive is a locomotive powered by electricity from overhead lines, an on-board energy storage device such as a chemical battery or fuel cell. Electricity is used to eliminate smoke and take advantage of the high efficiency of electric motors. 3
HISTORY 1st Electric locomotive was built by:- a Scotsman, Robert Davidson of Aberdeen in 1837 & powered by BATTERIES. 1st Electric passenger train was presented by:- Werner von Siemens at Berlin in 1879. Driven by a 2.2 kW motor & reached a maximum speed of 13 km/h. Fig.1 Von Siemens Experimental Train 4
HISTORY Railways first introduced to India in 1853 & journeyed of 22 miles Between Bombay to Thane. Fig.2 5
OVERVIEW OF ELECTRIC LOCOMOTIVE Now a days all locos are running through Electricity with the help of OHE line. Pentagraph is used to connect the loco with OHE line. Loco contains 2 Bogies, each Bogie consist of 6 wheels. So totally loco consists of 12 wheels. Pantagraph draws 25 KV of electricity from OHE line, which is very high AC voltage. Fig.3 Pentagraph 6

Electrical equipments generate a lot of heat during their normal operation. Hence the different auxiliaries provided for cooling and other purposes. These locos is described below:- 8

ADVANTAGES OF THREE PHASE TECHNOLOGY It Require little maintenance. 3-標 drive allows regeneration and unity power factor operation. It improves operational efficiency besides reduction in maintenance efforts. The energy saving due to regeneration and improved power factor sizable. 28
ADVANTAGES OF ELECTRIC LOCOMOTIVE Electric engines do not produce much heat and noise. Electric engines are therefore easier to maintain whereas the moving parts of a diesel engine require constant maintenance. The simple nature of the electric engine makes them efficient and powerful. 29
ADVANTAGES OF ELECTRIC LOCOMOTIVE Electric engines are light weight, constituting only motors and wheel axles, and have almost no moving parts. Do Not Produce Smock. Fig.23 DIESEL LOCOMOTIVE 30
CONCLUSION Main Objective was to learn electric locomotive In Railways. I am thankful to the supporting people of the POH Bhusawal. Electricity is used to eliminate smoke and take advantage of the high efficiency of electric motors. 31
