DIESEL-ELECTRIC LOCOMOTIVES
INTRODUCTION
An understanding of the structure of a locomotive mechanically and electrically is essential to a
person attempting to perform maintenance and repair services on it. The reference text on which this
subcourse is based is a broad presentation of locomotive structure and a basic outline of maintenance
and repair procedures. Upon completion of the subcourse, you should be able to identify the mechanical
parts of a diesel-electric locomotive, to explain how the components of the electric system work, to
describe maintenance procedures required to keep the locomotive running properly, and to troubleshoot
for various malfunctions. The subcourse consists of four lessons and an examination, divided as
follows:
Credit hours
Lesson 1, Mechanical Structure
