Page 3 - The principal requirements of" permanent way" are; that it be well drained, and especially in contiguity to the substructure. That the weight and damaging power of the engines and rolling stock, should be considered as the datum for calculation. That the strength, hardness, and tenacity of the rails, and the immobility of the substructure, should be adapted for the hardest work to which the railway is to be subjected. That the substructure should have an amount of bearing surface, proportioned to...
Page 12 - There are several advantages in this system ; the form of the sleeper is strong, — it holds well in the ground ; — the chair is not liable to be detached, — the whole bearing surface is directly beneath the load, — the ballast is always kept dry and elastic, — and there is an extremely ingenious contrivance for packing it through two holes, with a pointed rammer, from the surface, so that the sleeper and rail can be forced upwards, without disturbing the general bed of ballast, or they...

Page 32 - ... could supply, in order to avoid those disputes, which the protection of a successful invention was nearly certain to induce. It was well known, that upon all lines of railway, there were used a multitude of patented inventions, and therefore, inventors might be permitted to hope, that even Mr. Brunei's antipathy to patented inventions would eventually be modified, and that the deep girder rail might be admitted for trial on the Great "Western, or some other line of railway. Mr. ERRINGTON said...
Page 11 - Joint Chair. In applying the fish-joint to the repair of rails on lines, when funds had grown scarce, an objection arose to the cost of an extra sleeper and chair, in addition to the fishes. To meet this objection, Mr. Samuel contrived a modification of the 'fish.' (Figs. 21, 22, and 23.) Fig. 21. SAMUEL'S FISH CHAIR. Plan. A chair was cast with only one jaw, made to fit against one side of the rails, a wrought-iron fish being placed against the other si'de, and all bolted together through the rails...
Page 8 - ... locomotive work, for which they were not intended, no deduction can be drawn from them ; but they were weakened by the scarf, and were expensive in manufacture. On examining the joints of a railway out of order, it will be found, that the forward end of each rail, in the direction of the traffic, stands, apparently, slightly higher than the hinder end of the rail in front of it (Fig. 17). When the weight comes on it, so as to press it down to the chair, it becomes the lowest, as the under part...
Page 10 - Rail and fishing plates. and securing them in the chair. It was expected that the hinder rail in the line of progress, thus lapping over the forward one, would keep both down together. But whether from bad iron, or from the diminished strength of the parts, it was found that the ends broke off, and the plan was abandoned. At length, in the year 1849, the authorities on the Eastern Counties Railway resolved to try the experiment of the ' fishjoint.' Some half-dozen rails were jointed with cast-iron...
Page 4 - ... the joints should be so made, that the rails may, practically, become continuous bars, yet with freedom to expand and contract without being too loose. And with all this, there should be interposed, between the rails and the solid ground, some medium, sufficiently elastic to absorb the effect of the blows...
Page 27 - ... been carefully attended to ; but they were liable to fracture, if the substratum was not constantly kept well rammed beneath them : in short, like almost all other systems, if it was well attended to, it was durable, but, if not, the cast-iron way as soon got out of order as any other road. Mr. BRUNEL was anxious not to be misunderstood in what he had stated, relative to the contraction and expansion of rails ; he did not mean to imply, that iron rails were exempt from the ordinary effects due...
