The Iron Horse, R. M. Ballantyne [howl and other poems .txt] 📗

pounds a week, and the cost for the whole of the works more than 600,000 pounds. A curious fact connected with this enormous mass of iron is, that arrangements had to be made to permit of shrinkage and expansion. The tubes were placed on a series of rollers and iron balls, and it was afterwards found that in the hottest part of summer they were twelve inches longer than in winter—a difference which, if not provided for, would have caused the destruction of the towers by a constant and irresistible pull and thrust! The Menai Bridge was begun in 1846 and opened for traffic in March 1850.

Space would fail us were we to attempt even a slight sketch of the great engineering works that railways have called into being. We can merely point to such achievements as the high-level bridges at Newcastle-on-Tyne, Berwick-on-Tweed, and at Saltash, over the Tamar. There are viaducts of great height, length, and beauty in all parts of the kingdom; there are terminal stations so vast and magnificent as to remind one of the structures of Eastern splendour described in the Arabian Nights Entertainments; and there are hundreds of miles of tunnelling at the present time in the United Kingdom.

The Metropolitan Railway is the most important and singular of these tunnels—for it is entitled to be regarded as a gigantic tunnel—which burrows under the streets of London.

This stupendous work was undertaken in order to relieve the traffic in the streets of London. The frequent blocks that used to occur not many years ago in the main thoroughfares of the Metropolis, had rendered relief absolutely necessary. When the increase of railways began to pour human beings and goods from all parts of the kingdom into London in a continuous and ever-increasing stream, it became obvious that some new mode of conveyance must be opened up. After much deliberation as to the best method, it was finally resolved that an underground railway should be made, encircling the Metropolis, so that travellers arriving from all points of the compass might find a ready and sufficient means of conveyance into the central parts of the city. There was opposition to the scheme, of course; but, through the persevering energy of the solicitor to the undertaking and others, the work was at length begun, and the line opened for traffic in January 1863. Its extraordinary success soon proved the wisdom of its promoters.

At first it was thought that the chief revenues would be derived from the conveyance of goods from the west to the eastern districts of London, but its enormous passenger traffic eventually became the chief cause of its great prosperity. In the very first year of its opening the number of passengers who travelled by it between Farringdon Street and Bishop’s Road, Paddington, amounted to nearly nine and a half millions of individuals, which is more than three times the entire population of London—also, let us add, more than three times the entire population of Scotland!

The number of trains which are constantly following each other in quick succession (at times every two or three minutes) on this magnificent railway has rendered a most perfect system of signalling necessary, as well as a working staff of superior intelligence and activity. The drivers are all picked men, and indeed it is obvious to every one who travels by it that the porters, and guards, and all employed on the line are unusually smart men. The engineering difficulties connected with the Metropolitan railway were very great as may easily be believed, seeing that it had to be formed under streets whose foundations were unavoidably shaken, and amongst an infinite ramification of gas and water-pipes and sewers whose separate action had to be maintained intact while the process of construction was going on. Some of the stations are most ingeniously lighted from the streets above by bright reflecting tile-work, while others, too deep for such a method, or too much overtopped with buildings to admit of it, are lit perpetually with gas. The whole of the works are a singular instance of engineering skill, reflecting great credit on Mr Fowler, the engineer-in-chief. Despite its great length of tunnelling the line is perfectly dry throughout.

At first fears were entertained that human beings could not with safety travel through such tunnels as were here formed, but experience has proved those fears, like many others, to have been groundless, and a very thorough analysis of the atmosphere of the line in all circumstances, and by the most competent men of the day, has demonstrated that the air of the Metropolitan railway is not injurious to health. The excellent general health of the employés also affords additional and conclusive testimony to this fact even although it is unquestionably true that there is at times a somewhat sulphurous smell there.

This thorough ventilation, of course, could only have been achieved by ingenious arrangements and a peculiar construction of the engines, whereby the waste steam and fumes of the furnaces should be prevented from emitting their foul and sulphurous odours. The carriages are brilliantly lighted with gas, contained in long india-rubber bags on their roofs, and the motion of the trains is much gentler than that of ordinary railways, although they travel at the rate of from fifteen to twenty miles an hour, including stoppages,—a rate, be it observed, which could not have been ventured on at all but for the thorough and effective system of telegraphic and semaphore signalling employed, to indicate from station to station the exact state of the line—as to trains—at all times. On the whole the Metropolitan Railway has proved one of the most useful and successful undertakings of modern times. See Note 3 at the end of the chapter.

In reference to foreign railways, we have only space to say that there are works as grand, and as worthy of note, as any of which we can boast; and it is with much regret that we feel constrained to do no more than point to such magnificent undertakings as the Mont Cenis Railway, which ascends and tunnels through the Alps; and that stupendous line, the Union Pacific Railroad, 3000 miles in length, formed by the daring and enterprising Americans, by means of which the prairies and the Rocky Mountains are made of no account and New York is brought within seven days of San Francisco! The engineering works on the Sömmering Railway, between Vienna and Trieste; the mighty Victoria Tubular Bridge at Montreal; the railway bridge over Niagara; the difficulties encountered and overcome in India; the bold achievements of railway engineers amid the dizzy heights and solitudes of the Andes—all these subjects must be passed over in silence, else our readers will, we fear, come to the conclusion that we have lost command of the Iron Horse altogether, allowed him to take the bit in his teeth and fairly run away.

Note 1. Many readers may find it difficult to form an adequate conception of such a vast number as 307 millions. It may help one to some idea of it to know that, if a man were to devote himself to count it, one by one,—sitting down after breakfast counting at the rate of one every moment, and working without intermission for eight hours every day, excepting Sundays,—he would not conclude his task until the thirty-fifth year.

Note 2. We would refer them particularly to Messrs W. and R. Chambers’ comprehensive and popularly written work on “Railways, Steamer, and Telegraphs;” Money’s “Rambles on Railways,” which bristles with figures and swarms with anecdote; “Stokers and Pokers,” by Sir Francis Head, a capital and very full work, though somewhat old; W.B. Adams’ “Roads and Rails,” and Bremrer’s “Industries of Scotland.”

Note 3. We had intended to devote much larger space to this most interesting line, but the nature of our book forbids it. We quit the subject regretfully; referring the reader, who may desire to know more, to an able notice of the Metropolitan Railway in “The Shops and Companies of London,” edited by Henry Mayhew.
