But suppose we improve upon that well-paved highroad. There is not a concrete nor an asphalt highway in the world that is comparable with the polished surface of the smooth steel rail. The tractive power of any unit increases vastly when it is used--often as high as twenty-five times.
In other words, and to drop simile, we take off the expensive rubber tires of the motor-truck and substitute for them the steel, flanged wheels of the railroad-car or locomotive. Presto! We have a completely self-contained locomotive far lighter than the lightest practicable steam locomotive and running at about a 35 per cent. power economy, while with that locomotive we combine the freight-car or the passenger-car, or both.
"If it were not for the gasolene-motor unit I should not be able to operate this little road to-day," says the general manager, superintendent, and all-around Pooh-Bah of a short-line up in the hills of northwestern Pennsylvania.
I know precisely what he means. His oil comes from near-by wells. He buys it at a great economy. His good-sized truck--it will carry seven or eight tons of freight or passengers--is enabled to make six round-trips a day over twelve miles of line at far less cost than a small locomotive and train would involve for but two round-trips a day. In other words he has tripled his service, with inevitable beneficial results to the passenger-traffic of the little road, and has made real savings in his operating costs. A road which otherwise would have been added to that appalling total of abandoned railroad mileage for 1921 has been saved, to the great benefit of the communities that it serves.
Not long ago I rode from Kane to Mount Jewett, twelve miles across the hills of that same northwestern corner of Pennsylvania. I wanted to catch the northbound flyer of the Buffalo, Rochester, and Pittsburg railroad out of the latter town. Between Kane and Mount Jewett there stretches a rather remote branch of one of America's largest and best operated railroads. It was in the dead of winter and I should have preferred to ride upon a railroad train. But one train a day and missing the important connections gave me no opportunity whatsoever. I was forced to ride in a motor-bus upon a slippery ice-coated highway. Twenty-three other persons, the most of them also trying to catch the northbound flyer of the B. R. & P., were doing the same thing. The bus made four trips a day in each direction and the driver said that it was not only good business but steady. He charged seventy-five cents for the ride in each direction, which was something more than six cents a mile. A good many people complain at paying more than 3.6 cents a mile upon the rail, but they are not usually short-haul riders.
