by Vince and Colomb, that by the use of steam-power on railroads a much more rapid and cheaper transit of persons as well as merchandise might be confidently anticipated. He leaped far ahead of many of even the most hopeful advocates of the cause, and with almost prophetic foresight wrote, “there is scarcely any limit to the rapidity of movement these iron pathways will enable us to command.” And again,—“We have spoken of vehicles travelling at twenty miles an hour; but we see no reason for thinking that, in the progress of improvement, a much higher velocity might not be found practicable; and in twenty years hence a shopkeeper or mechanic, on the most ordinary occasion, may probably travel with a speed that would leave the fleetest courser behind.” Wonderful words these! At a first glance we may not deem them so, being so familiar with the ideas which they convey, but our estimate of them will be more just if we reflect that when they were penned railways had scarcely sprung into being, steam locomotives had only just been born, and not only men in general, but even many learned, scientific and practical men regarded the statement of all such opinions as being little short of insanity. Nevertheless, many deep-thinking men thought differently, and one contemporary, reviewing this subject in after years, said of Mr Maclaren’s papers, that, “they prepared the way for the success of railway projectors.”
We have said that the steam locomotive—the material transformer of the world—our Iron Horse, had just been born. It was not however born on the rails, but on the common road, and a tremendous baby-giant it was, tearing up its cradle in such furious fashion that men were terrified by it, and tried their best to condemn it to inactivity, just as a weak and foolish father might lock up his unruly boy and restrain him perforce, instead of training him wisely in the way in which he should go.
But the progenitors of the Iron Horse were, like their Herculean child, men of mettle. They fought a gallant fight for their darling’s freedom, and came off victorious!
Of course, many men and many nations were anxious to father this magnificent infant, and to this day it is impossible to say precisely who originated him. He is said by some to have sprung from the brains of Englishmen, others assert that brains in France and Switzerland begat him, and we believe that brother Jonathan exercised his prolific brain on him, before the actual time of his birth. The first name on record in connexion with this infant Hercules is that of Dr Robison, who communicated his ideas to Watt in 1759. The latter thereupon made a model locomotive, but entertained doubts as to its safety. Oliver Evans, of Philadelphia, patented a “steam waggon” in 1782. William Murdoch, the friend and assistant of Watt, made a model in 1787 which drew a small waggon round a room in his house in Cornwall. In the same year Symington exhibited a model locomotive in Edinburgh, and in 1795 he worked a steam-engine on a turnpike-road in Lanarkshire. Richard Trevethick, who had seen Murdoch’s model, made and patented a locomotive in 1802. It drew on a tramway a load of ten tons at the rate of five miles an hour. Trevethick also made a carriage to run on common roads, and altogether did good service in the cause.
Blenkinsop, of Middleton Colliery, near Leeds, made locomotives in 1811 which hauled coals up steep ascents by means of a toothed rail, with a toothed propelling wheel working into it. This unnatural infant, however, turned out to be not the true child. It was found that such a powerful creature did not require teeth at all, that he could “bite” quite well enough by means of his weight alone,—so the teeth were plucked out and never allowed to grow again.
After this, in 1813, came Brunton of Butterley, with a curious contrivance in the form of legs and feet, which were attached to the rear of his engine and propelled it by a sort of walking motion. It did not walk well, however, and very soon walked off the field of competition altogether.
At last, in the fulness of time there came upon the scene the great railway king, George Stephenson, who, if he cannot be said to have begotten the infant, at all events brought him up and effectually completed his training.
George Stephenson was one of our most celebrated engineers, and the “father of the railway system.” He may truly be said to have been one of mankind’s greatest benefactors. He was a self-taught man, was born near Newcastle in 1781, began life as a pit-engine boy with wages at two-pence a day, and ultimately rose to fame and fortune as an engineer.
In 1814 he made a locomotive for the Killingworth Colliery Railway. It drew thirty tons at the rate of four miles an hour, and was regarded as a great success. In 1825 an engine of the same kind was used on the Stockton and Darlington Railway, of which Stephenson had been made engineer.
But the great crowning effort of Stephenson, and the grand impulse to the railway cause, which carried it steadily and swiftly on to its present amazing degree of prosperity, did not occur till the year 1829.
Previous to that date the Manchester and Liverpool Railway was being constructed, and so little was known as to the capabilities of railways and the best mode of working them, that the directors and engineers had some difficulty in deciding whether the line should be worked by fixed engines or by locomotives. It was ultimately decided that the latter should be used, and a premium of 500 pounds was offered for the best locomotive that could be produced, in accordance with certain conditions. These were— That the chimney should emit no smoke—that the engine should be on springs—that it should not weigh more than six tons, or four-and-a-half tons if it had only four wheels—that it should be able to draw a load of twenty tons at the rate of ten miles an hour, with a pressure of fifty pounds to the square inch in the boiler, and should not cost more than 500 pounds.
The Iron Horse was now at last about to assume its right position. It was no longer an infant, but a powerful stripling—though still far from its full growth; as far as six tons is from sixty!
Four iron steeds were entered to compete for the prize. It was in October 1829 that this celebrated trial came off, and great was the interest manifested on the occasion, for not only did the public entertain doubts as to the capabilities of locomotives, but very few even of the engineers of the country would admit the possibility of a locomotive engine attaining a speed greater than ten miles an hour! First came the “Novelty” of Braithwaite and Ericson; then the “Sans pareil” of Hawkworth; the “Perseverance” of Burstall; and, lastly, the “Rocket” of Stephenson. Of the first three we shall merely say that the “Novelty,” being weak in the wheels, broke down; the “Sans pareil” burst one of her cylinders; and the “Perseverance” turned out to be too heavy to comply with the conditions of the trial.
The “Rocket” advanced, and was harnessed to a train of waggons weighing thirteen tons; the fire was lighted, and the steam got up. The valves lifted at the stipulated fifty pounds pressure, and away it went with its load at an average speed of fifteen, and a maximum speed of twenty-nine miles an hour! Thus triumphantly the “Rocket” won the prize of 500 pounds, and the Iron Horse was fairly and finally married to the Iron Road. One of the important elements of Stephenson’s success lay in the introduction of numerous tubes into his boiler, through which the fire, and heat passed, and thus presented a vast amount of heating surface to the water. Another point was his allowing the waste steam to pass through the chimney, thus increasing the draught and intensifying the combustion; for heat is the life of the locomotive, and without much of this, high rates of speed could not be attained.
The difference between the first locomotive and those now in use is very great—as may be seen any day in London, by any one who chooses to visit one of our great railway stations, and go thence to the Kensington Museum, where the “Rocket” is now enshrined—a memorial of Stephenson’s wisdom, and of the beginning of our magnificent railway system. Yet though the difference be great it is wonderful how complete the “Rocket” was, all things considered. The modern improvements made on locomotives consist chiefly in clothing the boiler with wood, felt, and other non-conductors to increase the life-giving heat; in heating the feed-water, coupling the driving-wheels, working the cylinders horizontally, economising steam by cutting off the supply at any part of the stroke that may be required, and economising fuel by using raw coal instead of coke, and consuming the smoke, besides many other minor contrivances, but all the great principles affecting
