Bkest, J.,

delivered the opinion of the Court.

It appears from the facts in this case, that the Northern Central Railway Company, after the year 1855, and before 1859, constructed, at its^ole cost and charge, a railway track upon the lands of the Canton Company, with the license and permission of the latter. The route adopted was agreed upon between them, and at the time of the construction of the road, the appellant had reason to believe it yyas laying its railroad upon land over which it had the free right of way. Whatever may have been the misunderstanding, as subsequently developed, between the companies, it was then believed by both of them that arrangements could be effected by which a continuous road,. resulting in their mutual benefit, would be constructed from some point, in or near Baltimore city, on the main stem of the appellant’s road to navigable water. Its construction, however, was prevented by circumstances, which it is unnecessary for the purposes of this case to notice in detail. The appellee, satisfied that the connection would not be made, thought proper in 1859 to revoke the license under which the appellant was in possession of its land. This was followed in 1860 by two suits; one an action of ejectment, and the other of trespass quare clausum fregit. During *352the pendency of these suits, which had been referred by agreement to an arbitrator, the appellant filed a bill for specific performance, and also praying for an injunction. The appellee was successful in having the bill dismissed, and. recovered judgment in both actions at law. A subsequent action of ejectment was brought in January, 1865, for the road-bed, which had not been embraced in the previous ejectment suit. A judgment therein was obtained in June following, and under a writ of habere facias possessionem, possession was delivered to the appellee in October of the same year. The rails and other materials, which formed a part of the railway constructed by the appellant under the circumstances above stated, were upon the land at the time, and the question arises who is the rightful owner of them ?

The fact that they had been taken up and severed from the soil shortly before the execution of the writ of possession is immaterial. If the appellant had no title to them while attached as a railway to the soil, thesseverance did not confer any.

The . general rule of the common law certainly is, that whatever is fixed and annexed to the soil becomes a part of it, and cannot be removed except by him who is entitled to the inheritance. But this rule is by no means inflexible and ■ without exception. Trade fixtures have been held by the earliest cases in which the question arose, to form an exception. No matter how strongly attached to the soil or firmly imbedded in it, they are treated as personal property, and as such subject to removal by the person erecting them. In the leading case of Elwes vs. Mawe, 3 East, 38, (2 Smith’s L. C., 251,) the earlier and more important decisions upon this subject are very fully reviewed by Lord ElleNBoeoug-h, and his conclusion from them, that trade fixtures and buildings for trade have always been recognized as an allowed exception to the general rule, has been acquiesced in, without an exception, as correctly stating the law. The distinction which he makes against fixtures for agricultural purposes has been doubted, *353and regarded as too nice and technical, but there is no case in which the exception has not been held to apply to trade fixtures. In Van Ness vs. Pacard, 2 Peters, 37, the exception is recognized by the Supreme Court of the United States, Story, J., delivering the opinion, and the doctrine applied to a house, which had been erected as an accessory to the business of a dairyman, although it was occupied as the residence of his family and those employed by him. It is also recognized and asserted in Holmes vs. Tremper, 20 John. Rep., 29; White’s Appeal, 10 Barr., 252, and authorities there cited.

Another exception to the general rule is, that of structures upon the land of another, which have been erected by the builder at his own cost and for his own exclusive use, as disconnected with the use of the land. If so erected with the knowledge and assent of the owner of the land, the title remains in the builder; and the property is held by him as a personal chattel. Thus it is not so much the character of the structure as the circumstances under which it was erected, that will determine whether it passes with the realty, or is to be treated as personal property. In the notes to the cases of Prince vs. Case and Rerick vs. Kern, 2 Amer. L. C., 747, it is cori’ectly said, the American Courts have repeatedly held that a house or other building will not be merged in the land on which it stands in consequence of the solidity of its structure or the connection between it and its foundations, if the agreement of. the parties and the purposes.of justice require, that the title to both should be kept separate, and that the owner of the house should have the right to enter for the purpose of using it as his own, or removing it.” In the case of Dame vs. Dame, 38 N. H., 429, this doctrine was applied to a house erected upon the land of another, and it was held to be but a personal chattel. It is also established by Curtiss vs. Hoyt, 19 Conn., 165; Wells vs. Banister, 4 Mass., 514; Barnes vs. Barnes, 6 Vermont, 388; Pemberton vs. King, 2 Devereux, 376, and being personalty, it is governed by the same rules as any other personal property left by the consent of the *354owner of tbe land upon his premises. Smith vs. Benson, 1 Hill, 176.

We consider the property in dispute in this case, as coming within both of these exceptions. The railway, of which it formed an important and necessary part, cannot rationally be supposed to have been designed for any other purpose, than that of trade connected with the ordinary business and pursuits of a railway company. It certainly was not accessory to the enjoyment of the freehold, or in any manner necessary and convenient for the occupation of the land by the party entitled to the inheritance. Had it been voluntarily abandoned, it is not pretended that it would or could have been used by the appellee as a railway. The conclusion cannot be avoided that it was built by the appellant with a view and for the purpose of facilitating and increasing the business and trade, in which the corporators, under their corporate powers, had embarked as carriers. A railway is certainly quite as essential to the trade and business of a railway company, as a steam engine and the house which may cover it, or any other fixture can be to the miller or the miner. We do not mean to be understood as denying the doctrine laid down in the Farmers’ Loan and Trust Co. vs. Hendrickson, 25 Barbour, 484, and cited with approval in 18 Md., 193, that the road bed of a railway, the rails fastened to it, and the buildings at the depots are real property. Prima fade, a house with its foundation planted in the soil is real property, yet when it is accessory to trade, and in law a trade fixture, we find all the authorities regard it as personal property. The same doctrine is applicable to the railway in question. As a general rule, it would be regarded as real property, but under the circumstances of this case, coming as it does within the definition of a trade fixture, it becomes personalty, liable to the same rules of law that govern any other personal property.

All the surrounding circumstances shew that at the time this railway was laid upon the land of the appellee, it was not intended that it should be merged in the freehold. It was *355built at the sole cost of tbe appellant, with its money and labor, under the reasonable belief tb.at it had a free right of way, and under the license and by the permission of the owner of the soil. It' is true this license was not of such a character as made it irrevocable, or gave the appellant any sufficient standing in a Court of equity, to obtain a decree for a specific performance, yet it was a license j ustifying an entry, and whatever was done under it, before its revocation, is to be regarded as legal, and not as tbe act of a trespasser. The road thus laid must have been intended by both parties for the exclusive use of the railway company, and that use could not have been fully enjoyed without the right to hold and control it. The appellant could not otherwise have directed its management, and taken up and replaced such rails or other materials as were necessary in its judgment for the repairs and proper condition of the road.

The strict rule which has been applied to tenants, requiring them to remove fixtures, which they hold as personal property during the term, even if it were adopted by this Court, does not apply to tbe present ease. The-ground upon which a tenant’s right to remove his fixtures, has been limited during the continuance of his term, rests upon the doctrine that if he neglected to avail himself of his right within this period, the law presumed that he voluntarily relinquished his claim in favor of the landlord. This presumption cannot arise where the term being uncertain in its continuance, may be terminated suddenly and without previous notice. To apply it to a party in possession under a license revocable at pleasure, would be manifestly unjust and without reason. It would be allowing a party, without any fault of his own, or any opportunity of removal, to be deprived of his property at the mere will and caprice of another.

If the property replevied did not belong to the appellee at the time the license to the appellant to be upon its land was revoked, it is not perceived bow tbe subsequent suits between them could have changed the title to it. This property was *356not the subject of those suits. They had reference to the land only upon which it Aras, and determined no question of its ownership, inasmuch as it does not pass with the realty from the single circumstance of having been affixed to the soil.

(Decided 12th March, 1869.)

Upon a careful review, of the law and facts in this case, we cannot agree with the Court below. "We think the property in question belonged to the appellant, and that the judgment helow should be reversed.

Judgment reversed, and judgment for the appellant for the property replevied, . and one cent damages and costs.
