Electric ticket-reserving system

STEADILY increasing difficulties have marked the expansion of the reservation systems of railroads and air lines over the past two decades. This may in large part be due to the greater number of people traveling today, to the increased speed of the vehicles, and perhaps also to the efforts that the carriers have made in supplying a large variety of accommodations. A large railroad can provide 12 different types of space such as berths, club chairs, roomettes, and so forth, all of which must be recorded in the reservation department to assure that every available seat is sold and at the same time to prevent duplicate selling that would irritate to the passenger and endanger good public relations.
