Symonds, J.
Tbe three parcels of real estate in Bangor referred to as tbe Hinckley, Lord, and Lord and Yeazie lots, tbe European and North American Eailway Company, in tbe fall of 1870, contracted in writing to purchase. Possession was then taken by tbe corporation, and has been retained by those in charge of tbe railroad from that time to tbe present. Tbe payments required by the contracts were made by that company, and afterwards by tbe consolidated company, and by tbe trustees under each mortgage during tbe period of their possession. Tbe premises have been used and improved at considerable expense for depot grounds; tbe principal improvements having been made before consolidation.
Tbe contracts were assigned by tbe European and North American Eailway Company, September 12, 1870, to Jewett, Woods and Emery, to secure them against liability as indorsers on tbe first three of tbe notes given in each instance for tbe purchase money. But those notes were paid at maturity, tbe liability of tbe indorsers was at an end, and their right to bold tbe collateral ceased. Tbe assignment bad served its purpose. Tbe interest it conveyed was commensurate only, in degree and in duration, with tbe liability it secured.
Tbe course of reasoning employed in tbe previous case, Hamlin et al. Trustees, v. Jerrard, leads directly to tbe conclusion, that tbe mortgage to tbe complainants in tbe first of these bills in equity, as trustees, operated upon tbe inchoate right of tbe *89Maine company to a conveyance of these lots under the contracts, as soon as they were executed and that company was in possession under them for the purposes of the charter. Their right to a conveyance, became at once subject in equity to the mortgage. The mortgagees, upon possession taken, were subrogated to the rights of the mortgagors. By our statute, such a right to the conveyance of lands, may be taken and sold on execution. B. S., c. 76, § 29. Such a mortgage may apply to it as well. At the date of a mortgage like this, given to obtain funds to complete construction, the corporation might be in possession of considerable portions of its road-bed under similar contracts to purchase; or it might subsequently acquire title to parts of its line in that way, instead of pursuing the statutory method. In either case, such after-acquired property, when in pursuance and upon performance of the contract the full title to it vests in the corporation, becomes part of a mortgaged estate. Any intermediate interest or right gained, is equally subject to the mortgage. The manner of acquiring the right of way, or depot grounds, cannot be important. It is upon the right acquired that the mortgage acts. Possession of lands under such circumstances and for such purposes, with the right on certain terms to perfect the title, may be as valuable an incident to the railroad itself, as necessary a part of it, as any lease-hold interest or higher estate it may have in another part of its line. See Barnard v. Norwich and Worcester Railroad, supra, where an after-acquired lease-hold interest was held to pass to the trustees under the mortgage.
Nor do we think a different rule applies, as to the payments made by the consolidated company upon these contracts during the period of its possession. Such payments stand upon the same footing as improvements made by that company upon the buildings and grounds. Its position, in reference to the plaintiffs as trustees and to the mortgaged property, is in some respects more truly defined by saying that it is its predecessor in title under a new name (and something more), than by regarding it merely as the assignee of the original company. It took the entire property, subject to incumbrances, and assuming the debts. *90Five millions of tbe consolidated bonds were to be used only to redeem and pay tbe first mortgage claims. If the exchange of bonds bad been completed, the whole consolidated property, with all future additions, would still have been incumbered by substantially the same debt as that secured by the plaintiffs’ mortgage, under a new form, and in its own name. If, at the date of consolidation, the Maine company had obtained a clear title to the depot grounds in Bangor, but was in debt for them, had received the deed, but had not paid the purchase money, it is clear that the grounds would have been subject to the plaintiffs’ mortgage, while the debt would have been one the consolidated company must pay. Or, if there had' been a mortgage on the same real estate when the Maine company receiyed its deed, supposing for the sake of illustration the deed to have been delivered and under such circumstances, and consolidated funds had paid it, the payment would have been of a debt it was the duty of that company to pay, that mortgage would have been discharged, and the plaintiffs’ mortgage would have become the first incumbrance upon the land. The mortgage to the plaintiffs attached to the right to a deed of the station-grounds as a part of the road itself, and it continued to attach to it as the right grew in value. The consolidated company, under the articles of union, was not an assignee of these contracts, discharged from the mortgage. The increased value of the right to a conveyance of real estate, which was in the occupation of the company and essential to the road, remained subject to the mortgage as an accession to the road, just as the increase of values along any part of the line, arising from improvements made by the consolidated company in its roadbed, track, or stations, added to the security of the first mortgage bondholders. If the consolidated company, taking the entire property of its predecessor in Maine, subject to mortgage, increased the value of the railroad, and the rights that go with it, by making payments or expending money, that gives it no equitable interest as against the mortgagees. If, at the consolidation, the title of the Maine company to a part of its road-way or yards was imperfect, and payments by the consolidated company perfected it, the mortgage holds the completed title. In *91regard to these three contracts for the real estate at the station in Bangor, it should be observed, also, that the interest in them which passed to the consolidated company at the consolidation, not only was subject to the mortgage in the sense already indicated, but it was also in its essence, a right, and nothing more, to acquire a thing, >yhieh, when acquired, as to these plaintiffs, was a part of the road mortgaged to them.
It is not doubted, that an interest in these contracts passed to the consolidated company by the terms of the articles of union. It would be to that company that the conveyances should be made, when the terms wrere fulfilled on which the contractors were obliged to give the deeds, unless a legal foreclosure of the plaintiffs’ mortgage had changed their interest as mortgagees into an absolute title. But a conveyance to the consolidated company, prior to foreclosure, would inure to the benefit of the plaintiffs, to the extent of their mortgage.
The Crosby lots were purchased and paid for by the European and North American Railway company, and the deed was delivered to them, before consolidation. The object of the purchase was to secure adequate terminal facilities and space for engine and car bouses, and other railroad accommodations. The road was located to and upon them, but was built only to within about four hundred and seventy yards, and the time for building under the charter, has expired. Eor all that appears, they were bought in good faith, in the exercise of the best judgment of the officers then, and for railroad purposes, at a time when the company bad a right and expected to build to them. The mortgage took effect upon them. That the expectations of business have not been realized, that the right to use them in direct connection vyith the road, without further legislative authority, has expired, does not relieve them from the incumbrance. They are claimed still, on grounds that the evidence would scarcely enable us to deny, to be necessary for the fixture development of tbe railroad. We could not say from the testimony, that the purchase was, at the time, an extravagant and unreasonable one. The case of a railroad holding more property for its own purposes than its present needs demand, is entirely different from .one in which the company buys *92other property, distinct from the road and its appurtenances, not intended or necessary for the present or prospective exercise of its franchise, and therefore not within the purview of the mortgage. We think there is nothing in the case to exclude the Crosby lots, or any part of the three lots in Bangor, from the effect of the mortgage, as property not therein intended to be acquired and conveyed.
The complainants in the first bill are entitled to an injunction against all the respondents named therein and in the amendment, restraining them from any interference with the complainants’ possession and control, as mortgagees, of the real estate therein described, and from any resistance of the complainants’ title to the same, to the extent of the trusts declared in the mortgage; the injunction to be made perpetual and without the limitation just stated, if the interest and title of the complainants has or shall become absolute by a legal foreclosure. The second bill is dismissed.
Decree accordingly.
