When George Stephenson was planning the Liverpool and Manchester line, the directors entreated him, when they went to Parliament, not to talk of going at a faster rate than ten miles an hour, or he "would put a cross on the concern." George was sanguine, however, and spoke of fifteen miles an hour, to the astonishment of the committee, who began to think him crazy. The average speed is now twenty-five miles an hour, and a mile a minute can be done, if need be. The wind is hard pushed to keep ahead of a good engine at its fullest speed.[C] The express trains on the "broad gauge" of the Great Western travel at the rate of fifty-one miles an hour, or forty-three, including stoppages. To attain this rate, a speed of sixty miles an hour is adopted midway between some of the stations, and even seventy miles an hour have been reached in certain experimental trips. The engines on this line can draw a passenger-train weighing one hundred and twenty tons at a speed of sixty miles an hour, the engine and tender themselves weighing an additional fifty-two tons. The ordinary luggage-trains weigh some six hundred tons each. The locomotive, however, goes on the principle that the labourer is worthy of his hire; if it works hard, it eats voraciously. At ordinary mail speed the engine consumes about twenty lbs. of coke per mile; so that, costing L2500 to begin with, and spending an allowance of L2000 a year--as much as an under-secretary of state--the locomotive is rather an extravagant customer--only, it works very hard for the money, and earns it over and over again. With all its strength and size, the locomotive is a much more delicate concern than would be supposed; the 5416 different pieces of which it is composed must be put together as carefully as a watch, and, though guaranteed to go two years without a doctor, exacts the most devoted attention from its guardians to keep it in order. It would fill a volume of huge dimensions to dilate on all the phases of the social revolution which the modern railway has wrought in our own and other countries; how it is daily annihilating time and space, and making the Land's End and John o'Groat's House next door neighbours; rubbing down old prejudices and jealousies, both national and provincial, promoting commerce, developing manufacture, transforming poor little villages into flourishing towns, and industrious towns into mighty cities; carrying civilization into the heart of the jungle and the desert, and, with its twin-brother, the steam-ship, joining hands and hearts in peace and amity all the world over. After the wonders of the last thirty years, who can doubt that our children, at the close of the century, will regard us as little less backward than we now do our fathers at its dawn?
