Excerpt from Handbook of Street-Railroad Location Tms book is designed to present to the student and engineer that part of the subject of street-railroad construction which is to be performed by the civil, rather than by the electrical engineer. It therefore includes, besides the trigonometrical problems pertaining to railroad curves, the general principles governing the choice of site, grades and curves. It is assumed that every one using the book will be familiar with the prac tice of land surveying and with the manipulation of surveying instruments, and no space is given to these subjects. The arrangement is believed to be that which gives the best result in the classroom, while the form and size are convenient for use in the field. Every principle is illustrated by the solu tion of a numerical example, and at the end of each article several problems are proposed to test the proficiency of the student.
