Excerpt from The Practice of Railway Surveying and Permanent Way Work The authors gained their experience 'as members of the stafis of two leading English Railways, and also when carrying out railway work abroad. The knowledge thus acquired of the best English practice, as well as of the methods adopted in the construction of economic railways in unexplored and undeveloped countries, has enabled them to deal with the subject from the practical point of view. Many of the methods described are original; some are traditional among Railway Engineers and some are those adopted 'by American Engineers, acquaintance with which is necessary for the more complete study of the subject. Little or none of the matter included under Permanent Way has previously appeared in print, and it is hoped that this will be of much assistance to the young permanent way engineer.
