In this line of books there is revealed the whole workings of a great American railroad system. There are adventures in abundance—railroad wrecks, dashes through forest fires, the pursuit of a “wildcat” locomotive, the disappearance of a pay car with a large sum of money on board—but there is much more than this—the intense rivalry among railroads and railroad men, the working out of running schedules, the getting through “on time” in spite of all obstacles, and the manipulation of railroad securities by evil men who wish to rule or ruin.
