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."
I then told him that but for the merest accident I should have met him on the same line at the rate of forty miles, and that I had attached to my engine my experimental carriage, and three waggons with thirty tons of iron. I then inquired what course he would have pursued if he had perceived another engine meeting him upon his own line.
Brunel said, in such a case he should have put on all the steam he could command, with a view of driving off the opposite engine by the superior velocity of his own.
