So the New Haven, with all the resources of a giant carrier, has found each new measure of relief swallowed up in the new flood and has turned to more radical methods. It has been apparent to its managers for some time past that even the new Grand Central, with its wonderful capacity, would some day prove inadequate, for the reason that the New York Central--the actual owners of the property--was also trying to cope with its own great increase in suburban traffic, and would eventually require more and more space for its own Commuters. With such a possibility in the future--not a distant future with the suburban business doubling in volume every four or five years--the New Haven sought to develop an unimportant freight branch leading from New Rochelle down to the Harlem River. It has almost finished the work of transforming this into a great electric carrier, six tracks in width. Railroad engineers show no hesitancy in saying that eight-track trunks will be needed out of New York in every direction within a dozen years. The Harlem River branch of the New Haven, once it is provided with a suitable terminal, will become a great artery of suburban traffic. It will give trunk capacity to make possible the development of a great new area lying just inland from the Sound, and yet within from 40 to 50 miles of New York City. A third project in which New Haven capital is known to be interested is that of a high-speed, four-track suburban electric railroad also to reach into the Sound territory as far as Port Chester, with an important branch, diverging to White Plains, the shire-town of Westchester County. This line will feed into the main line of the New York subway, and so avoid cramping the terminals still further. The terminals are the crux of the whole great problem of handling suburban traffic. The New York Central has also electrified its tracks for a zone of some 40 to 50 miles from its terminal. This work was started primarily by a distressing accident in its old smoke-filled tunnel, that ran the length of Park Avenue under Manhattan Island, but New York Central officers are to-day free to admit that the electrification was close at hand in any event. The operation of a terminal so closely planned as the new Grand Central, with its train-sheds and yards built in layers, would have been a physical impossibility with smoky, dirty, steam locomotives.
