Practical Locomotive Operating. E-book. Formato PDF - 9780243628490

Brevity has been adhered to in the presenting of the several subjects, because the spirit of the times demands it, even in the discussing of the most important things. The mathematical formula employed and the accompanying examples are also abbreviated, for the process is immaterial, provided the result is correct and is susceptible of easy explanation. This has not been done for the purpose of encouraging engineers and firemen to avoid mathematics or to discard theory, but there seems no good reason why they should be compelled to read through pages of unrelated matter when the desired information can be presented in a few terse and intelligent paragraphs. No attempt has been made to describe the construction, manage ment, and manipulation of the air-brake, which, although allied to locomotive operating, is comprehensively treated in books devoted solely to that subject. Furthermore, the air-brake is just now in a process of development, and so a treatise here would probably burden the book with matter that will become obsolete in a few years. A few other special appliances are given no place here, that are either in an experimental stage or have but local application, as they in no way affect the general scheme of modern locomotive Operating, which is thoroughly explained. If we succeed in making the latter plain to the average engineer, fireman, and aspirant to those positions, our object will be attained.
