There is a movement to-day toward the creation of a locomotive which shall be both inside and outside-connected. There is hardly room for two cylinders within the frame. There certainly is room for one. And with the retention of the two outer cylinders there presently will be created a locomotive which, with all its improved steam-creating powers to boot, will quickly take highest place both in speed and energy. More operating economies will be effected, new records established. The steam locomotive a laggard? Is not the question now fairly answered? CHAPTER XI THE GASOLENE-MOTOR UNIT AND ITS POSSIBILITIES In the twelve months of 1921 service was abandoned upon 1626 miles of standard steam railroad in the United States--much of it permanently abandoned. Of this, 217 miles, or very slightly less than that of 1920, was not only abandoned, but the track was taken up and the equipment sold. In addition to all of this the various regulatory commissions had authorized the abandonment of 191 more miles of line, and applications were pending for the scrapping of still another 575 miles. Once fairly important roads, such as the Colorado Midland and the Colorado Springs and Cripple Creek (one fourth of the abandoned mileage was within the State of Colorado) and the Missouri and North Arkansas, are included within these totals, while to them are added a host of small railroads, lines twenty-five to forty miles in length or less. Unimportant? Yes, to you and me, when we go hurrying across the country in the Limited, but not infrequently of very large importance to the communities that they aim to serve.
