PREFACE.
This little book is written in the hope that it may be of service to those whose daily work is concerned with the art of transportation, in which electrical traction is today so potent a factor. The part it may play to-morrow only the prophet can say.
The author has endeavored to set forth the general principles of the distribution of electrical energy to moving motors, to describe the methods which experience has shown to be desirable in such work, and to point out the ways in which these principles and methods can be co-ordinated in everyday practice. The art of correctly designing systems of distribution requires, more than anything else, skilled judgment and infinite finesse; it cannot be reduced to formulae in which these terms do not enter as variables. The most that can be done is to sketch the lines of thought that, followed cautiously and shrewdly, lead to good results.
For the most part apparatus is too mutable to describe exhaustively, unless one is writing history. The reader will therefore find little of such detail, save in the frontier region which lies between established tramway practice and that greater field that stretches toward unknown bounds. Along that frontier experiment has blazed paths here and there, and we must note them carefully. We can see whither they lead, but dare not say how far.
The best advice that can be given to the engineer is to keep his eyes and ears open and never to let himself get caught out of sight of experimental fact.
