In this great single super-economy the railroads of eastern New York, Pennsylvania, Maryland, southern New England, and northern New Jersey may easily share. In fact it is definitely planned that they shall share in it. The list of feasible users of this concentrated power includes the Fitchburg division of the Boston and Maine, all the way from Boston to Rotterdam Junction, New York (oddly enough the western half of this division, from Greenfield to Rotterdam, through the Hoosac tunnel, 104 miles, has for some time since been marked for electrification by the road's own engineers); the connecting Delaware and Hudson from Mechanicsville, New York, to Wilkes-Barre, Pennsylvania; the New York, New Haven, and Hartford from the present terminal of the electric zone at New Haven through to Boston, both by the Shore line and the Springfield line (this predicates of course the electrical operation of the Boston and Albany all the way east of Springfield--and why not west of that point also is not easily discovered); the main line of the Erie, from Jersey City to Susquehanna, Pennsylvania; the Lackawanna, from Hoboken to Elmira; the Lehigh Valley from New York to Wilkes-Barre; the Central Railroad of New Jersey-Reading-Baltimore and Ohio group to Washington, to Hagerstown, Maryland, and to Gettysburg, Pennsylvania; the Pennsylvania, from New York to a point just beyond Harrisburg--all of these main lines and a host of their branches. Such is the railroad portion of this embracing scheme. The only important road in its territory that is omitted from the electric program is the New York Central, which has such low grades and hence such economical use of power that the economy of electricity is least necessary to it. If ever it should desire to cooperate in the plan, it probably can gain the power for its main line--west of Albany, at least--from Niagara Falls, and for its network of busy lines in northern New York from the abundant water-powers of the Adirondack preserve or the huge St. Lawrence River international power project.
