Down in the offices of the old Cumberland Valley Railroad at Chambersburg, we will say, there is a boy who is assistant trainmaster or assistant superintendent. He is a smart boy, who has climbed rapidly in railroad ranks because of his abilities. He reads the papers. He is keenly interested in this whole idea of national defense. He reads the newspapers and the magazines and he wonders what his own part would be if Washington were taken by an enemy invader. Being a good railroader he does not have to spend much time in doubts. He knows that his little railroad--ever an important cross-country traffic link from Harrisburg down to Martinsburg and Winchester, will suddenly become part of the military base line north and south along the Atlantic coast. Over its stout rails will come the tidal overflow that ordinarily moves over the four busy tracks of the two railroad systems between Baltimore and Philadelphia. That means that his railroad, his own division, himself, if you please, will be called upon to handle a great traffic from Harrisburg south to the upreached arms of the Norfolk and Western and the Baltimore and Ohio lines. That young man in the Chambersburg railroad office should be under a course of instruction today, as to the emergency use of his railroad, his division. The division is the operating unit of the railroad in America. Therefore a scheme for the military use of the railroad should begin with its head, the superintendent. In the superintendent's office of every railroad division that may have possible military value, there should be a member of the army reserve corps, making the plan for the possible military use of his division. In the general superintendent's office there should be another reserve officer studying the schemes of the several divisions that center there. Similarly the process should be repeated in the general manager's and the president's offices, where authority converges still further. This is important work, vital training, if you please. It is hardly the sort of detail work to be placed upon the shoulders of a railroad executive, already burdened with a vast amount of other detail. * * * * *
