Transactions of the American Society of Civil Engineers, Vol. LXX, Dec. 1910 Locomotive Performance On Grades Of Various Lengths, Paper No. 1172 By: B. S. (Beverly S.) Randolph
In Transactions of the American Society of Civil Engineers, Vol. LXX, Dec. 1910, Beverly S. Randolph presents a thorough analysis of locomotive performance on grades of various lengths. The paper, numbered 1172, offers valuable insights for engineers and enthusiasts interested in understanding how locomotives operate on different gradients. Randolph's research is well-organized and supported by data and diagrams that effectively illustrate the relationship between grade length and locomotive performance. The author's writing is clear and concise, making complex concepts easy to comprehend for readers of all levels of expertise in the field of civil engineering. One of the strengths of the paper is the practical applications of the information presented. Randolph not only discusses the theoretical aspects of locomotive performance on gradients but also considers real-world scenarios and the implications for railway construction and operation. This makes the paper relevant and useful for anyone involved in the planning and maintenance of railroad infrastructure. Overall, Randolph's paper in Transactions of the American Society of Civil Engineers is a valuable contribution to the field of civil engineering, providing a comprehensive analysis of locomotive performance on grades of varying lengths. It is a must-read for professionals and students looking to deepen their understanding of this important aspect of railway engineering.

LOCOMOTIVE PERFORMANCE ON GRADES OF VARIOUS LENGTHS.

BY BEVERLY S. RANDOLPH, M. AM. SOC. C. E.

WITH DISCUSSION BY MESSRS. C. D. PURDON, JOHN C. TRAUTWINE, JR., AND BEVERLY S. RANDOLPH.

In the location of new railways and the improvement of lines already in operation, it is now well recognized that large economies can be effected by the careful study of train resistance due to grades and alignment, distributing this resistance so as to secure a minimum cost of operation with the means available for construction.

While engaged in such studies some years ago, the attention of the writer was attracted by the fact that the usual method of calculating the traction of a locomotive by assuming from 20 to 25% of the weight on the drivers was subject to no small modification in practice.

In order to obtain a working basis, for use in relation to this feature, he undertook the collection of data from the practical operation of various roads.
