“Where ever do they all go to?” murmured Mrs Marrot.
“Why,” replied Will Garvie, “they go to all the stations on the line, of course; some of ’em go to smash at once in cases of accidents, and all of ’em goes to destruction, more or less, in about fifteen or twenty years. We reckon that to be the life of a locomotive. See, there’s a drivin’ axle, such as you saw forged by the big hammer, being turned now, and cut to shape and size by the same sort of machine that you saw cuttin’ the tyres.”
They passed on, after looking at the axle for a few minutes, until they came to a part of the building where rails were being forged. This also, although not done by hammer, was a striking process. The place was so hot owing to the quantity of uncooled metal on the floor, that it was not possible to remain long; they therefore took a rapid survey. In one place several men were in the act of conveying to the steam-hammer a mass of shapeless white-hot iron, which had just been plucked from a furnace with a pair of grippers. They put it below the hammer for a few minutes, which soon reduced it to a clumsy bar; then they carried it to a pair of iron rollers driven by steam. The end of the bar being presented to these, it was gripped, dragged in between them, and passed out at the other side, flat and very much lengthened, as well as thinned. Having been further reduced by this process, it was finally passed through a pair of rollers, which gave it shape, and sent it out a complete rail, ready to be laid down on the line.
Here Garvie took occasion to explain that steel rails, although very expensive, were now being extensively used in preference to iron rails, because they lasted much longer. “For instance,” he said, “steel costs about 12 pounds a ton and iron only costs about 7 pounds; but then, d’ye see, steel rails will last two years and more, whereas iron rails get wore out, and have to be renewed every six weeks in places where there’s much traffic.”
“Now, I can’t stand no more o’ this,” said Mrs Marrot, down whose face the perspiration was streaming; “I’m a’most roasted alive, an’ don’t understand your explanations one bit, Willum, so come along.”
“Oh, mother, do hold on a moment,” pleaded Bob, whose mechanical soul was in a species of paradise.
“You’d better come, Bob,” interposed Garvie, “else we won’t have time to see the department where the engines are fitted.”
This was sufficient for Bob, who willingly followed.
The fitting shed at that time contained several engines in various stages of advancement. In one place men were engaged in fitting together the iron framework or foundation of a locomotive, with screws, and bolts, and nuts, and rivets. Others were employed near them, on an engine more advanced, in putting on the wheels and placing the boilers and fire-boxes, while another gang were busy covering the boiler of a third engine with a coating of wood and felt, literally for the purpose of keeping it warm, or preventing its heat from escaping. Farther on, three beautiful new engines, that had just been made and stood ready for action, were receiving a few finishing touches from the painters. Fresh, spotless, and glittering, these were to make their début on the morrow, and commence their comparatively brief career of furious activity—gay things, doomed emphatically to a fast life! Beyond these young creatures lay a number of aged and crippled engines, all more or less disabled and sent there for repair; one to have a burst steam-pipe removed and replaced, another to have a wheel, or a fire-box or a cylinder changed; and one, that looked as if it had recently “run a-muck” against all the other engines on the line, stood sulkily grim in a corner, evidently awaiting its sentence of condemnation,—the usual fate of such engines being to be torn, bored, battered, chiselled, clipt, and otherwise cut to pieces, and cast into the furnaces.
While gazing round this apartment, Mrs Marrot’s eyes suddenly became transfixed.
