Consider for an instant, if you will, the possibilities of the electrified passenger terminal as applied to some others of our metropolitan American cities. Take Boston, for instance. In that fine old town the electrification of its two great passenger terminals some time ago approached the dignity of becoming a real issue. Oddly enough the two railroads which would develop the situation in the larger of its two terminals--the South Station--are the New Haven and the New York Central, the lessee of the Boston and Albany. Though both of these systems participate in the joint operation of the new Grand Central Terminal of New York, neither of them has leaped at the possibility in Boston. The tremendous financial difficulties through which the New Haven property has been struggling for the last six or eight years and from which it has not yet emerged, are undoubtedly the cause of this. The Boston and Maine Railroad, which owns and operates the North Station, is in even worse financial plight. And it is hard for an outsider to see any immediate possibility of the application of electric power to the great North Station and the vast network of through and suburban lines which radiate from it. Nor is the North Station so situated as to render it possible today to give it an economic development even approximating that of the Grand Central. [Illustration: THE P. R.
