There are other American cities where this experiment--no longer an experiment, if you please--might well be effected today. Of these, more in a moment. For, before we leave the question of the Grand Central consider one other thing: the economic value of its design to the railroad company which has erected it. It was only a moment ago that we were speaking of the utter extravagance shown in the designing and building of the monumental passenger stations in so many of our metropolitan cities. The New York Central, for reasons of its own, has been reticent in stating both the cost of the new Grand Central and the income which it derives not only from the rentals of the privileges in the station itself--restaurants, news stands, barber shops, checking stands, and the like--but also from the ground rental of the great group of huge buildings which it has permitted to spring up over its electrified station yards. It is known, however, that this income is not only sufficient to pay the interest upon the investment of the new terminal, to provide slowly but surely a sinking fund for the retirement of the bonds which have been issued for the building of the terminal, but also to go a considerable distance toward the actual operating expenses of the terminal. Here, then, is the first of our giant opportunities for the railroader of tomorrow. There is, of course, no novelty in rentals from ordinary station privileges. The Pennsylvania Railroad, by the development of the electric locomotive, was enabled to tunnel both the Hudson and the East rivers and thus to realize its dream of long years--a terminal situated in the heart of Manhattan Island; a passenger terminal so situated as to place the great railroad of the red cars in a real competitive position with the railroad of the Vanderbilts, which so long had held exclusive terminal facilities within the congested island of Manhattan. The Pennsylvania did not do the thing by halves--it rarely does; it built what is beyond the shadow of a doubt the most beautiful railroad station in America, if not in the entire world. The majesty of its waiting room is such as to make it perhaps the loveliest apartment in all these United States.
