Description

Transactions of the American Society of Civil Engineers, Vol. LXX, Dec. 1910 - Locomotive Performance On Grades Of Various Lengths, Paper No. 1172

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 locomotiveby assuming from 20 to 25% of the weight on the driverswas 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. Subsequent engagements in an entirely different direction caused this to be laid aside until the present time. The results are given in Table 1, from which it will be seen that the percentage of driver weight utilized in draft is a function of the length as well as the rate of grade encountered in the practical operation of railways. ......Buy Now (To Read More)
