Excerpt: ... purely theoretical ideas on this subject. Thus we find that passenger locomotives which travel twenty five to forty miles per hour cost usually much less for their repairs than freight engines which move at half the speed. It is true they draw less than half the loads of the latter, and the internal strain upon their boilers and machinery is correspondingly reduced. Upon roads much-curved, the effect of increased velocity will necessarily be the most felt. Yet, although the pressure against the outer rail should be in the double ratio of the velocity, the actual cost of maintenance is not in that proportion as between slow and fast trains, if the testimony or rather the opinions of track-repairers is to be believed, which is the only specific evidence that can be had upon the subject, as it is impossible to assign to each class of trains its true share of the expense of adjustments and renewals. On the whole, inasmuch as there are several elements of the cost of maintaining track and rolling s tock which are independent of the speed of the trains, while there are others which may increase more rapidly than the simple velocity, and as the effect of speed is variously felt upon roads of different amounts and de grees of curvature, I think no reliable formula can be framed for application to every variety of road. Yet, while this may be true, it would not do to leave this element out of view in comparing different lines of road. Thus, if the same aggregate time is allowed for traversing two lines of unequal length, the longer line would require the higher velocity, and the wear and tear of rolling stock and road would be increased thereby, relatively to the other line, and perhaps no safer, certainly no simpler, rule would be than the ratio...

Download or read book Navaho Expedition written by James Hervey Simpson and published by University of Oklahoma Press. This book was released on 2003 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1849, the Corps of Topographical Engineers commissioned Lieutenant James H. Simpson to undertake the first survey of Navajo country in present-day New Mexico. Accompanying Simpson was a military force commanded by Colonel John M. Washington, sent to negotiate peace with the Navajo. A keen observer, Simpson kept a journal that provided valuable information on the party’s interactions with Indians and also about the land’s features, including important pueblo ruins at Chaco Canyon and Canyon de Chelly. His careful observations informed subsequent military expeditions, emigrant trains, the selection of Indian reservations, and the charting of a transcontinental railroad. Editor Frank McNitt discusses the expedition’s lasting importance to the development of the West, and his research is enriched by illustrations and maps by artists Richard and Edward Kern. Military historian Durwood Ball contributes a new foreword.
