The soundness of this advice became evident a very short time after it was given. On arriving one morning at the terminus, the engine which had been promised for my experimental train was not ready, but another was provided instead. On further inquiry, I found that the “North Star,” the finest engine the Company then possessed, had been placed at the end of the great polygonal building devoted to engines, in order that it might be ready for my service in the morning; but that, during the night, a train of twenty-five empty ballast-waggons, each containing two men, driven by an engine, both the driver and stoker of which were asleep, had passed right through the engine-house and damaged the “North Star.”

Most fortunately, no accident happened to the men beyond a severe shaking. It ought, however, in extenuation of such neglect, to be observed that engine-drivers were at that period so few, and so thoroughly overworked, that such an occurrence was not surprising.

It then occurred to me, that being engaged on a work which was anything but profitable to myself, but which contributed to the safety of all travellers, I might, without {323} impropriety, avail myself of the repose of Sunday for advancing my measures. I therefore desired Brunel to ask for the Directors’ permission. The next time I saw Brunel, he told me the Directors did not like to give an official permission, but it was remarked that having put one of their own officers under my orders, I had already the power of travelling on whatever day I preferred.

I accordingly availed myself of the day on which, at that time, scarcely a single train or engine would be in motion upon it.

Upon one of these Sundays, which were, in fact, the only really safe days, I had proposed to investigate the effect of considerable additional weight. With this object, I had ordered three waggons laden with thirty tons of iron to be attached to my experimental carriage.

On my arrival at the terminus a few minutes before the time appointed, my aide-de-camp informed me that we were to travel on the north line. As this was an invasion of the usual regulations, I inquired very minutely into the authority on which it rested. Being satisfied on this point, I desired him to order my train out immediately. He returned shortly with the news that the fireman had neglected his duty, but that the engine would be ready in less than a quarter of an hour.

A messenger arrived soon after to inform me that the obstructions had been removed, and that I could now pass upon the south, which was the proper line.

I was looking at the departure of the only Sunday train, and conversing with the officer, who took much pains to assure me that there was no danger on whichever line we might travel; because, he observed, when that train had departed, there can be no engine except our own on either line until five o’clock in the evening. {324}

Whilst we were conversing together, my ear, which had become peculiarly sensitive to the distant sound of an engine, told me that one was approaching. I mentioned it to my railway official: he did not hear it, and said, “Sir, it is impossible.”—“Whether it is possible or impossible,” I said, “an engine is coming, and in a few minutes we shall see its steam.” The sound soon became evident to both, and our eyes were anxiously directed to the expected quarter. The white cloud of steam now faintly appeared in the distance; I soon perceived the line it occupied, and then turned to watch my companion’s countenance. In a few moments more I saw it slightly change, and he said, “It is, indeed, on the north line.”

Knowing that it would stop at the engine-house, I ran as fast I could to that spot. I found a single engine, from which Brunel, covered with smoke and blacks, had just descended. We shook hands, and I inquired what brought my friend here in such a plight. Brunel told me that he had posted from Bristol, to meet the only train at the furthest point of the rail then open, but had missed it. Fortunately, he said, “I found this engine with its fire up, so I ordered it out, and have driven it the whole way up at the rate of fifty miles an hour.”
