Sixty-Eighth streets. On June 18, 1875, an act of the legislature, known as the “Rapid Transit Act, ” was passed. By that act a system was established under the provisions of which authority could be acquired to construct elevated railroads over public streets and highways, and it was provided in that act that the use of the streets, avenues, places, and lands authorized to be used for the purposes of such highway should be considered, and was thereby declared to be, a public use consistent with the uses for which the streets, roads, avenues, and public places were publicly held. That act also contained a provision which required, as a condition for the construction of any elevated railroad under the authority thereby granted, that the consent of the local authorities having the control of that portion of the street or highway upon which it is proposed to construct or operate such railway or railways be first obtained. In pursuance of the provisions of that act the defendant the New York Elevated Railroad Company was authorized to construct an elevated railroad in Third avenue, between Sixty-Seventh and Sixty-Eighth streets, and on September 7, 1875, the common council of the city of New York duly adopted and the mayor duly approved the following resolution: “Resolved, that this board, on behalf of the corporate authorities of the city of New York, hereby gives its consent to the routes adopted by the commissioners on rapid transit as contained in the report of the said commissioners transmitted to the board this day.” Acting under the authority thus granted by the corporate authorities, the defendant constructed its railroad in Third avenue, between Sixty-Seventh and Sixty-Eighth streets. Subsequently, in the year 1885, the mayor, aldermen, and commonalty of the city of New York conveyed to the plaintiff’s grantor the premises described in the complaint in this action, abutting on Third avenue, and the plaintiff now brings this action, alleging that she acquired, virtue of the grant from the city of New York to her grantor, and by the grant from her grantors to herself, an easement in Third avenue, which has been appropriated by defendant in the construction and operation of its railroad, and asks for an injunction to restrain the defendants from trespassing upon or appropriating such easement. And the question that meets us on the threshold of this case is whether the consent given by the city of New York to the defendant to construct its road in Third avenúe did not grant to this railroad company its right in Third avenue as abutting owner as well as its right and interest as owner of the fee of the street.
The city of New York, as a municipal corporation, held all of the property which it owned for public use. It held the fee of the street for a specific public use, viz., that of a public street; and it had no authority, except by consent of the legislature, to appropriate any of the property held in trust to be used as a street for any purpose except a street use, but all the property that was vested in the corporation was corporate property, and could not be applied to any use except corporate use without the consent of the legislature. The legislature, however, had power to authorize the municipal authorities to consent to the use of its property for any public use, and for such purpose it had power to declare what should be a public use. It had power, therefore, to declare that the elevated railroad should be deemed a public use, and to authorize the corporate authorities to devote any of the property that it held, whether in trust for public streets or for the general municipal purposes, to the use of such railroad, and when, acting under such authority, the corporation granted the right to use any of its property for the construction of such railroad, and the railroad company acted upon such consent, and built its road, the right to use such property so devoted for the railroad vested absolutely and irrevocably in the railroad corporation, and neither the city nor the legislature could subsequently resume possession of such railroad property without the consent of such railroad corporation. Thus, in the case of People v. O'Brien, 111 N. Y. 38 , 18 N. E. Rep. 692 , Ruger, C. J., says: “The
