"Cheap?" said he, in reply to one of my questions. "Of course they are cheap. That is the point of it. They rise and fall with the contour of the highroad because that saves expensive grading work. But you will notice that the highroads that they follow almost invariably are in the fairly level portions of France, and so the grades are not such that a well-designed locomotive, even if a fairly small one, cannot traverse them without difficulty. The lines curve sharply to make the highway bridges--but separate bridges would cost money and our narrow-gages primarily are cheap railroads. And our little locomotives are not bothered with the curves. They are extremely well-designed for their own purposes, and so when our line makes a right angle from one highroad to another, because a long easy curve would mean a separate right-of-way, possibly tearing down houses into the bargain, our well-designed locomotive brings ten or twelve or even thirteen loaded cars around that sharp turn in the highroad with little or no difficulty." The Frenchman rose and came around his office table, pointing his finger in my face. "Don't you see? Can't you understand?" he went on. "We have saved that immensely costly thing that you Americans call 'overhead.' The owners of one of these little roads of ours have not tied up a small fortune for every mile of them in grading and bridge-work and copper wire and power-houses. Our locomotives are small--always well-designed, mind you, and so not so very expensive, yet only one or two or three are required for the entire service of our average narrow-gage. The best of these cost far less than the smallest dynamos, to say nothing of car-motors, while the poorest of them will haul our little cars." There is a big lesson for America in these little roads. All of our highways are not improved highways; only a very small proportion of them are, in fact. It will be many, many years before any large proportion of them are completed. One shrinks at the very contemplation of so vast a task, while, as I have said, there is a growing disinclination against the use of our new paved roads as railroad tracks, particularly for heavy freight service. The most of them are too narrow; and even the wider roads are gradually pounded to pieces by the all-year use of ponderous motor-trucks. Remember that the average life of the best of the highways in the State of New York, where the manufacture of these roads has reached a high degree of perfection, is but seven or eight years at the most. Suppose that we were to begin the business of laying down light narrow-gage lines along many of the important highroads of the United States--not parallel to our standard railroads but in every case feeding in or out of them. They would not have to be more than twenty-four or thirty inches in gage and they could be built in the same efficient and economical way as those in France.
