INTRODUCTION

The purpose of this manual is to furnish enginemen with information essential for the operation of EMD Diesel switching locomotives. Details of construction are described sufficiently to provide the engineer and fireman with a basic working knowledge of the locomotive and its equipment.

The manual is divided into gecttons, with the section number and designation shown at. the top of each page. Section 0 contains an index to the manual, a list of illustrations and charts, general data and illustrations of the 600 HP and 1000 HP switching locomotives. Section 1 and succeeding sections cover the Description, Instruments and Controls, Operation and Location of Difficulties for the various models. These sections are looseleaf in form so that, revised pages may be inserted in the manual should changes in procedures and equipment be made.
