St.1.35 PREFACE IN preparing this book it has been the author's aim to explain Train Rules and Train Orders in such a way as to make them as clear as possible. The factors which have been instrumental in developing the present system of train operation are mentioned whenever it seems necessary to better enable the student to understand the necessity for any particular rule. The Rulings in this book are based upon the Rulings which the American Railway Association have made from time to time, but, while the interpretations given herein are correct and safe, still, the author wishes to caution trainmen that whenever they conflict with rules or rulings under which they are working, they must follow the instructions of their own road. In other words it is not the purpose of the book to take the 5 place of the rulings which the management of any road sees fit to make. This book is intended to make the rules clear, giving information which it is impossible for any railroad company to incorporate within a book of rules, explaining the rules and the reason for the different rules in such a manner as to be of special value in assisting examining officers to thoroughly explain the rules in detail, and also to thoroughly prepare trainmen to pass an examination with credit to themselves and their department. In looking up special points the index will be found of great value as it enables the student to turn to any subject instantly. G. E. COLLINGWOOD. July, 1917 |
