To come to actual cases: It was good railroading when the centralized Washington administration began assembling various sections of various lines so as to gain not only more direct routes between important traffic centers but lines of lowest possible gradients as well. In the West particularly, great progress was made in this direction. For instance in the old days of competitive railroading the Southern Pacific quite naturally operated its through route from Dallas or Fort Worth to Los Angeles and San Francisco over its own tracks through San Antonio or El Paso. Of course the old-time and somewhat unfortunate Texas and Pacific had a far shorter route from Dallas and Fort Worth direct to El Paso, but the competitive situation, the fact that it was the Texas and Pacific and not the Southern Pacific, prevented it from getting much volume of traffic for its short line. Under government unification the T. & P. line came into its own, with the result that 500 miles were taken off the through route between the important North Texas cities and southern California--with great resultant time and operating economies.
Similarly, there arose a war-time assembled through line from the oil-fields at Casper, Wyoming, to Montana and Puget Sound points, 880 miles shorter than the route which the competitive situation formerly forced. Freight from southern California to Ogden was hauled 201 miles less than by the pathway formerly used; while the Railroad Administration route between Chicago and Sioux City was 110 miles shorter than the old, and 289 miles were saved in the through traffic between Kansas City and Galveston and Houston. Multiply these examples and it is easy to see how in a period of sixty days in the summer of 1918 nine thousand freight-cars were so rerouted as to effect a saving in mileage traveled by each car of about 195 miles, or a total saving of about 1,754,805 car-miles.
To be ranked with this sort of operating economy was the work undertaken by Regional Director R. H. Aishton at Chicago when early in the spring of 1918 he began consolidating train movements so that instead of the several competing trunk-lines coming down from out of the Northwest, each operating competing through freight-trains each day into the great terminal and interchange yards at St. Paul, and there shifting and resorting their cars incredibly for distribution between the six trunk-lines leading for another five hundred miles down into Chicago, through trains were operated solidly from the Puget Sound points through to Lake Michigan. For through freight the great railroad yards upon the line between St. Paul and Minneapolis represented no more of a stop than was necessary for changing engines, cabooses, and crews. Moreover these through trains were distributed in alternation between the Northern Pacific and Great Northern lines from the Pacific coast down to the Twin Cities, but because of its superior mileage and gradient conditions they were handled on to Chicago almost exclusively by the Northwestern.
