Andrew Carnegie：Autobiography of Andrew Carnegie, Additional Excerpt 97

The railway was a single line. Telegraph orders to trains often became necessary, although it was not then a regular practice to run trains by telegraph. No one but the superintendent himself was permitted to give a train order on any part of the Pennsylvania system, or indeed of any other system, I believe, at that time. It was then a dangerous expedient to give telegraphic orders, for the whole system of railway management was still in its infancy, and men had not yet been trained for it. It was necessary for Mr. Scott to go out night after night to break-downs or wrecks to superintend the clearing of the line. He was necessarily absent from the office on many mornings.
