But the locomotive again triumphed. The Stephenson Coast Line secured the approval of Parliament; and the shareholders in the Atmospheric Company were happily prevented investing their capital in what would unquestionably have proved a gigantic blunder. For, less than three years later, the whole of the atmospheric tubes which had been laid down on other lines were pulled up and the materials sold—including Mr. Brunel’s immense tube on the South Devon Railway—to make way for the working of the locomotive engine. George Stephenson’s first verdict of “It won’t do,” was thus conclusively confirmed.
Robert Stephenson used afterwards to describe with great gusto an interview which took place between Lord
Howick and his father, at his office in Great George Street, during the progress of the bill in Parliament. His father was in the outer office, where he used to spend a good deal of his spare time; occasionally taking a quiet wrestle with a friend when nothing else was stirring. [309] On the day in question, George was standing with his back to the fire, when Lord Howick called to see Robert. Oh! thought George, he has come to try and talk Robert over about that atmospheric gimcrack; but I’ll tackle his Lordship. “Come in, my Lord,” said he, “Robert’s busy; but I’ll answer your purpose quite as well; sit down here, if you please.” George began, “Now, my Lord, I know very well what you have come about: it’s that atmospheric line in the north; I will show you in less than five minutes that it can never answer.” “If Mr. Robert Stephenson is not at liberty, I can call again,” said his Lordship. “He’s certainly occupied on important business just at present,” was George’s answer; “but I can tell you far better than he can what nonsense the atmospheric system is: Robert’s good-natured, you see, and if your Lordship were to get alongside of him you might talk him over; so you have been quite lucky in meeting with me. Now, just look at the question of expense,”—and then he proceeded in his strong Doric to explain his views in detail, until Lord Howick could stand it no longer, and he rose and walked towards the door. George followed him down stairs, to finish his demolition of the atmospheric system, and his parting words were, “You may take my word for it, my Lord, it will never answer.” George afterwards told his son with glee of “the settler” he had given Lord Howick.
So closely were the Stephensons identified with this measure, and so great was the personal interest which they were both known to take in its success, that, on the news of the triumph of the bill reaching Newcastle, a sort of general holiday took place, and the workmen belonging to the Stephenson Locomotive Factory, upwards of 800 in number, walked in procession through the principal streets of the town, accompanied with music and banners.
It is unnecessary to enter into any description of the works on the Newcastle and Berwick Railway. There are no fewer than 110 bridges of all sorts on the line—some under and some over it. But by far the most formidable piece of masonry work on this railway is at its northern extremity, where it passes across the Tweed into Scotland, immediately opposite the formerly redoubtable castle of Berwick. Not many centuries had passed since the district amidst which this bridge stands was the scene of almost constant warfare. Berwick was regarded as the key of Scotland, and was fiercely fought for, sometimes held by a Scotch and sometimes by an English garrison. Though strongly fortified, it was repeatedly taken by assault. On its capture by Edward I., Boetius says 17,000 persons were slain, so that its streets “ran with blood like a river.” Within sight of the ramparts, a little to the west, is Halidon Hill, where a famous victory was gained by Edward III., over the Scottish army under Douglas; and there is scarcely a foot of ground in the neighbourhood but has been the scene of contention in days long past. In the reigns of James I. and Charles I., a bridge of 15 arches was built across the Tweed at Berwick; and in our own day a railway-bridge of 28 arches has been built a little above the old one, but at a much higher level. The bridge built by the Kings, out of the national resources, cost £15,000, and occupied 24 years and 4 months in the building; the bridge built by the Railway Company, with funds drawn from private resources, cost £120,000, and was finished in 3 years and 4 months from the day of laying the foundation-stone.
This important viaduct, built after the design of Robert Stephenson, consists of a series of 28 semicircular arches, each 61 feet 6 inches in span, the greatest height above the bed of the river being 126 feet. The whole is built of ashlar, with a hearting of rubble; excepting the river parts of the arches, which are constructed with bricks laid in cement. The total length of the work is 2160 feet. The foundations of the piers were got in by coffer-dams in the ordinary way, Nasmyth’s steam-hammer being extensively used in driving the piles. The bearing piles, from which the foundations of the piers were built up, were each capable of carrying 70 tons.
Another bridge, of still greater importance, necessary to complete the continuity of the East Coast route, was the masterwork erected by Robert Stephenson between the north and south banks of the Tyne at Newcastle, commonly known as the High Level Bridge. Mr. R. W. Brandling, George Stephenson’s early friend, is entitled to the merit of originating the idea of this bridge as it was eventually carried out, with a central terminus for the northern railways in the Castle Garth. The plan was first promulgated by him in 1841; and in the following year it was resolved that George Stephenson should be consulted as to the most advisable site for the proposed structure. A prospectus of a High Level Bridge Company was issued in 1843, the names of George Stephenson and George Hudson appearing on the committee of management, Robert Stephenson being the consulting engineer. The project was eventually taken up by the Newcastle and Darlington Railway Company, and an Act for the construction of the bridge was obtained in 1845.
The rapid extension of railways had given an extraordinary stimulus to the art of bridge-building; the number of such structures erected in Great Britain alone, since 1830, having been above 25,000, or more than all that had before existed in the country. Instead of the erection a single large bridge constituting, as formerly, an epoch
