delivered the opinion of the court,

The New Haven and Northampton Company is a Connecticut corporation, authorized to construct and opérate a railroad from New Haven, through the town of Southington, to the Massachusetts State line.. It has full power to erect and maintain .toll-houses and other buildings for the accommodation of its concerns, as it may deem suitable for its interest; but its *2 charter may “ be altered, amended, or repealed at the pleasure of the General Assembly.” ■ In 1848, after the road'was built, three stations' were established in the town of Southington, named respectively Southington, Plantsville, and Hitchcock’s, ■at which trains stopped for freight and passengers.

In 1866, the General Assembly'of the State passed a statute Avhich contained the following provision in respect to the abandonment of railroad stations: —

“No railroad company shall abandon any station on its road in this State after the same has been established for twelve months, except by the approval of the railroad commissioners, given after a public hearing held at such station, notice of which'shall be posted conspicuously in said station for one month prior to the hearing.”

In November, 1873, the company became desirous of abandoning one or more of its stations in Southington, and for that purpose presented a., petition to the railroad commissioners, representing that two stations properly located would be ample for the public convenience, and asking that the matter might be inquired into, and that the Southington or Plantsville station, or both, might be discontinued, and' tivo stations, and only two, located in the town, where the common good of all parties in interest Avould be most promoted. The requisite notice Avas given, and the commissioners having heard the application, on the 3d of February, 1874, made the following order: —

“ After a careful and full examination of the locality and business surroundings of the present located stations, and an extended hearing of all the appearing parties in interest, Avith their evidence and arguments of counsel, the railroad commissioners do find and approve, and do hereby order, that the NeAV Haven and Northampton Company may discontinue and abandon the present stations of Southington and Plantsville, as at present located, under’ and by complying Avith the following provisions and conditions, viz.: —

“ The NeAV Haven and Northampton Company shall provide and erect a passenger station house near their neAv freight depot, as shown on the map exhibited and submitted, and after and in compliance Avith the plans and profiles also submitted for said passenger station building, and provide suitable and *3 .convenient approaches thereto; also suitable, convenient, and 7 easy approaches to their new. freight' depot; all of which shall' be done to the acceptance, of the railroad commissioners. Said - company shall also continue the same facilities for receiving and shipping freight by the óar-load and unbroken, as at present enjoyed,- to each and all of-, the parties who patronize their railroad by receiving and shipping freight thereby.” •

Before this time the company had bought the ground , and erected buildings adapted to freight business at the place indicated in the order. It afterwards, at an expense of $10,000, put up a building for passenger purposes, as required by the commissioners. This being acceptable to the commissioners, • the stations of Southing-ton and Plantsville-were abandoned by the Company, and both passenger and freight trains stopped at the new place bnly.

The succeeding legislature passed an act, approved July 15i < 1875, “ establishing, a depot at. Plantsville.” It is as follows; —

“ Sect. 1. That if, at any time within six months after the passage of this act, any of the petitioners and others who may act with, them for that purpose shall 'erect at Plantsville, contiguous to the ■railroad, a depot building, and convey .the same, .with the land on which it is situated, and the land reasonably necessary for the approaches thereto by the railroad trains, to the New Haven and Northampton Company, to be used for railroad purposes, it shall thereupon become the duty of. said company, and it is hereby ordered, to stop at-such depot thereafter its regular passenger and freight trains passing over said railroad, for the purpose of receiving and discharging passengers and freight. And all the provisions of the Revised Statutes applicable to railroad depots and stations shall be applicable to said depot in the same manner as though said depot had been erected and established by said company.

“ Sect. 2. Said order may be enforced by mandamus by the attorney for the State for the-county of Hartford,- or atr.thé relation of any inhabitant of the town of Southington, in said .county, and', the charter of the New Haven and Northampton Company is hereby amended according to the provisions of this act.”

The petitioners named complied with the provisions of the-act, and, having tendered the company a conveyance of suitable depot grounds and buildings at Plantsville, demanded that *4 the regular passenger and freight trains running on the road. be stopped there. This the company refused to do, and. the attorney for the State for the county of Hartford now seeks by mandamus to enforce the law. The court below gave judgment against the company; holding, among other things, that the act of 1875 did not impair the obligation of any contract rights which the company had acquired from the State. Upon this ground the case has been brought here by writ of error. .

It was conceded in the argument that there is nothing in. the charter to prevent the State from passing the law complained of. Confessedly the power of amendment which was reserved meets this part of the case ;■ but it is claimed that by the action of .the'railroad commissioners the State has become bound by -a contract not to exercise its- legislative power so as to require the establishment of a.depot at Plantsville.

• As it seems to us, the court of errors of the State, took the right view of the statute under which the commissioners acted, when they said, in State of Connecticut v. New Haven & Northampton Co. (87 Conn. 153,163), that its object was “ to prevent railroad companies from. arbitrarily changing their, places of business on the road, to the prejudice of .those who, relying on the permanency of such places, shape their business accordingly.” The powers of the commissioners, as' agents of the State, in this particular, are confined to such as are necessary for the accomplishment of that object. They may, after a public hearing, approve of, that is to say, gi^e the assent of the State to, the abandonment of a station which has been established twelve months or more; aiid that is all they can do. They may, as was held in State v. New Haven & Northampton Co. (42 id.-56)„direct that their approval take effeot only when the company shall have provided suitable accommodations for the public at some other place; but that is only á conditional approval of the' abandonment. When the new accommodations.have been provided and the old station abandoned, nothing more has been accomplished, so far as. the company is concerned, .than a lawful abandonment of an old place of business. -The powers.'of the State over the charter remain just as they were before. ■ Until the act of 1866 the company could abandon its stations at will, and the State by charter amendment, or even *5 by a general law, might require- their, restoration. • After that act the power of abandonment by the company was restricted, but the State retained all its old authority^ The commissioners were given no power to contract for the State or the. public. All they could do was to say yes or no to a- simple request by the company for ..leave to abandon an old station. -If they'said yes, the abandonment might be made; if no, the station must be continued- In this case the commissioners said, “ Yes, when the new accommodations are furnished.” The new accommodations were, furnished, and the station was abandoned accordingly. Such, in the case last cited, was the view which the court of errors took of what had been done, and we think it is correct; The commissioners - entered into no agreement with the company. They simply said, complete your proposed accommodations at the néw station, and we, for the State, will assent .to your abandonment of the old one. It follows that the new law impaired no contract obligation of the State, and the judgment of the court of errors is consequently Affirmed.
