Runways, in connection with steam engine machinery, are vast mechanical enterprises that have, within a few years, been extensively applied to the purpose of effecting inland transportation with unprecedented rapidity, certainty, and great comparative economy. The railway itself, however, is believed to be of considerable antiquity, although of a very rude construction, being first used only for temporary purposes. Railways of a more permanent character, it is certain, have been in use, in the mining districts of England, for at least two hundred years. On these, the heavy minerals were slowly transported, either by manual labour, horse-power, or by gravity; and, in some few cases, slow-motioned locomotive steam engines were in use for several years anterior to their application to commercial transportation. It was the favourable results obtained with these engines on the mineral railways, together with the establishment of the very important facts, that the resistance from friction did not increase with an increase of velocity, and that the adhesion of the engine wheels on the cast iron rails, then alone in use, was adequate to the traction, that first led to their projection and successful application in the rapid transportation of persons and property.

Paperback. Zustand: New. Print on Demand. This book is an examination of railway structures in the early to mid-19th century with an emphasis on the structural weaknesses in the railways of the time. The author provides a thorough description of the various methods used in railway construction up to that time and identifies several fatal flaws in these designs, including a tendency for the ground underneath the rails to compress under the weight of passing trains. The author's proposed solutions involve major changes to the way rails were laid and secured, including the use of longitudinal beams to support the rails instead of isolated blocks of stone or wood. By analyzing the tensile strain produced by the contraction of iron rails and other factors that contribute to wear and tear, the author makes the case that the railways of the time, such as the Great Western Railway and the Liverpool and Manchester Railway, could be greatly improved through the implementation of his proposed changes to railway structure.
