OPINION
For more than half a century, the Union Pacific Railroad (“Union Pacific”) has leased land under 1,800 miles of its right of way to Santa Fe Pacific Pipelines, L.P. (“SFPP”), which uses the land for a petroleum pipeline. In a suit by landowners challenging Union Pacific’s ability to lease the land, the district court held that (1) the acts of Congress conferring the right of way authorized Union Pacific to use the right of way only for a “railroad purpose,” and (2) the pipeline did not serve such a purpose. It then certified those issues for interlocutory review pursuant to 28 U.S.C. § 1292(b). We granted permission to appeal and, for the following reasons, disagree with the district court’s conclusions.
I
A. Historical Background
In the mid-19th century, the vast expanse of territory west of the Mississippi River “remained a largely untapped resource,” Leo Sheep Co. v. United States,
Enthusiasm for a transcontinental railroad was initially offset by fierce sectional debate over which route' the railroad should take. The deadlock was finally broken in the early 1860s, when seceding states stopped sending representatives and senators to Congress. Thus, development of a transcontinental railroad began in earnest against the backdr.op of the Civil War. See id. at 674, 99 S.Ct’. 1403 (“Senators and Representatives from those" States which seceded from the Union were no longer present in Congress, and therefore the sectional overtones of the dispute as to routes largely disappeared.”).
In 1862, Congress passed, and President Lincoln signed, “[a]n Act to aid in the Construction pf a Railroad and Telegraph Line from the Missouri River to the Pacific Ocean.” Act of July 1, 1862, ch. 120, 12 Stat. 489 (“1862 Act”). The 1862 Act chartered Union Pacific’s predecessor and authorized it to build a railroad from the Nebraska Territory to the western border of the Neyada Territory. See id. § 1,
To assuage scruples about its constitutional authority to directly subsidize internal improvements, Congress based these acts—which we refer to as the “pre-1871 Acts”—on its “Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States.” U.S. Const, art. IV, § 3. Congress used this power in two ways. First, it granted the relevant corporation “the right of way through the public lands ... for the construction of [a] railroad and telegraph line.” 1862 Act, § 2. With one exception, the grant extended “two hundred feet in width on each side of [the] railroad where it may pass over the public lands,” and included “all necessary grounds for stations, buildings, workshops, and depots, machine shops, switches, side tracks, turntables, and water stations.” Id.
In addition to granting these rights of way, “Congress embarked on a policy of subsidizing railroad construction by lavish grants from the public domain.” Great N. Ry. v. United States,
The checkerboard grants were controversial from the start and eventually fell out of favor. See James W. Ely, Jr., Railroads and American Law 58 (2001). Congress made no such grants after 1871, see id., although it continued to grant rights of way over public lands for the tracks of new railroads. That practice was streamlined in the General Railroad Right-of-Way Act of 1875, ch. 152, 18 Stat. 482 (“1875 Act”):
[T]he right of way through the public lands of the United States is hereby granted to any railroad company ... to the extent of one hundred feet on each side of the central line of said road; also the right to take, from the public lands adjacent to the line of said road, material, earth, stone, and timber necessary for the construction of said railroad; also ground adjacent to such right of way for station buildings, depots, machine shops, side tracks, turnouts, and water stations, not to exceed in amount twenty acres for each station, to the extent of one station for each ten miles of its road.
Id. § 1,
B. Legal Background
Inevitably, disputes arose over the nature of the rights acquired under both the pre-1871 Acts and the 1875 Act. In St.
In Northern Pacific Railway v. Townsend,
The substantial consideration inducing the grant was the perpetual use of the land for the legitimate purposes of the railroad, just as though the land had been conveyed in terms to have and to hold the same so long as it was used for the railroad right of way. In effect the grant was of a limited fee, made on an implied condition of reverter in the event that the company ceased to use or retain the land for the purpose for which it was granted.
By contrast, the Supreme Court held in Great Northern that the 1875 Act “clearly grants only an easement, and not a fee.”
But the Court muddied the waters somewhat fifteen years later. The issue in United States v. Union Pacific Railroad,
The Court in Union Pacific acknowledged Townsend and like cases, but distinguished them:
Some reliance is placed on a line of decisions of the Court which describe the rights of way under early railroad land grants as limited fees. These cases were, for the most part, controversies between the railroad and third persons and involved problems so remote from the present one as to be inapt as citations .... We do not stop to' examine the other cases using like language to describe the railroad’s right of way, because in none of them was there a contest between the United States and the railroad-grantee over any mineral rights underlying the right of way. The most that the “limited fee” cases decided was that the railroads received all surface rights to the right of way and all rights incident to a use for railroad purposes.
Id. at 118-19 (footnote omitted). Referring to the statutory language that granted the right of way “for the construction of [a] railroad and telegraph line,” 1862 Act, § 2, it held that, “whatever may be the nature of Union Pacific’s interest in the right of way, drilling for oil on or under it is not a railroad purpose within the meaning of § 2 of the Act.”
■In the late 1970s and early 1980s, two circuits invoked Union Pacific to determine the railroad’s interest in the land under its right of way. The Tenth Circuit held in Energy Transportation Systems, Inc. v. Union Pacific Railroad,
Some thirty-five years .later, the Supreme Court returned to both the pre-1871 Acts and the 1875 Act in Marvin M. Brandt Revocable Trust v. United States, — U.S. —,
[T]hat is directly contrary'to the very premise of this Court’s decision (and the Government’s argument) in Great Northern-, that the 1875 Act granted a fundamentally different interest in the rights of way than did the predecessor statutes. Contrary to the Government’s position now—but consistent with the Government’s position in 1942—Great Northern stands for the proposition that the pre-1871 statutes (and this Court’s decisions construing them) have little relevance to the question of what interest the 1875 Act conveyed to railroads.
Id. (citations omitted).
C. Litigation History
Union Pacific currently operates trains on more than 32,000 miles of track, including tracks it acquired from the Southern Pacific Railroad. The vast majority of Union Pacific’s track is built on rights of way acquired under both the pre-1871 Acts and the 1875 Act.
1. Union Pacific v. SFPP
In the 1950s, Southern Pacific leased the land under some of its rights of way to a sister company, which then built 1,800 miles of pipeline to transport petroleum products. Originally affiliates, the railroad and the pipeline company came under separate ownership in the 1980s, with Union Pacific eventually succeeding to Southern Pacific’s tracks and other railroad assets, and SFPP, a subsidiary of Kinder Morgan, acquiring the pipeline.
Union Pacific and SFPP entered into a series of agreements under which Union Pacific granted a perpetual easement to SFPP in exchange for fair market rent. In the event the parties could not agree on the fair market rent, the agreements contemplated a judicial proceeding in California state court.
In a proceeding to determine fair market rent for 2004 through. 2014, SFPP argued that the fair market rent for the easement should ■ be reduced because of questions about Union Pacific’s title to the rights of way. It did not, however, question Union Pacific’s right to grant the easement. In 2012, the state trial court held that Union Pacific had a sufficient property interest in the land beneath its rights of way to entitle it to collect rent for the pipeline.
The California Court of Appeal raised sua sponte at oral argument the issue of “whether the Railroad had the right to grant the Pipeline’s easements in the first instance, given the terms of the Congressional Acts and the extensive relevant case law.’’ Union Pac. R.R. v. Santa Fe Pac. Pipelines, Inc.,
2. District Court Proceedings
Spurred by the California Court of Appeal’s decision, owners of property that was formerly public land adjacent to the rights of way filed class actions seeking damages for trespass and under similar theories. Cases were filed in Nevada, Arizona, New Mexico and the Central District of California.
In this case, Union Pacific asserted counterclaims for declaratory relief and to quiet title. The district court granted the plaintiffs’ motion to dismiss those counterclaims, following what it called the “persuasive reasoning” of the state court’s “lengthy, well-researched, and thoughtful opinion.” In re SFPP Right-of-Way Claims, No. SACV 15-00718 JVS (DFMx),
1. Can Union Pacific authorize a use of the subsurface underneath the railroad right of way if the use does not serve a “railroad purpose”?
2. Can Union Pacific demonstrate a “railroad purpose” in granting a subsurface easement to a third party to operate a commercial petroleum pipeline through the subsurface of the rights of way?
Union Pacific timely petitioned for interlocutory review, which we granted.
II
A. Collateral Estoppel
We first address the appellees’ contention that we should not reach the merits of the certified questions, but should instead give preclusive effect to the California Court of Appeal’s decision under the doctrine of collateral estoppel.
Our jurisdiction under 28 U.S.C. § 1292(b) is limited to the certified order. See United States v. Stanley,
The appellees’ motion to dismiss argued that the district court should follow the California Court of Appeal’s decision both because it was binding on Union Pacific and because it was correct on the merits. The certified order, however, expressly decided the motion “without regard to collateral estoppel,” citing the state-court decision “for its persuasive value rather than its preclusive effect.” Although the district court stated that it would address collateral estoppel “[i]n a subsequent order,” it has not done so. In these circumstances, we think the “letter and spirit of § 1292(b),” Deutsche Bank,
B. Do the Acts Require a Railroad Purpose?
The phrase “railroad purpose” does not appear in either the pre-1871 Acts or the 1875 Act. Rather, it comes from the Supreme Court’s description in Union Pacific of the nature of the rights acquired under the statutes. With respect to the pre-1871 Acts, the Court held that “whatever may be the nature of Union Pacific’s interest in the right of way, drilling for oil on or under it is not a railroad purpose within the meaning of § 2 of the [1862] Act.”
Nevertheless, the first question certified by the district court asks, in essence, whether both the pre-1871 Acts and 1875 Act require a railroad purpose. That is a question of statutory interpretation and, therefore, our review is de novo. See Higher Taste, Inc. v. City of Tacoma,
1. Pre-1871 Acts
With respect to the pre-1871 Acts, the parties’ competing interpretations stem from the Supreme Court’s differing descriptions of the rights conveyed by the acts. Townsend squarely described the interest conveyed as a fee simple determinable, or in more modern parlance, a fee simple defeasible:
The estate in fee simple defeasible is a present interest that terminates upon the happening of a stated event that might or might not occur. The subcategories historically known as the fee simple determinable, the fee simple subject to a condition subsequent, and the fee simple subject to an executory limitation are no longer recognized but are absorbed under the term fee simple defea-sible.
Restatement (Third) of Prop.: Wills & Other Donative Transfers § 24.3 (Am. Law Inst. 2011). In describing the grant “as though the land had been conveyed in terms to have and to hold the same so long as it was used for the railroad right of way,” Townsend,
As the owner of the fee, the' railroad could do anything an owner in fee simple absolute could do, as long it was not inconsistent with the language of limitation. See Restatement (First) of Prop. § 49 (Am. Law Inst. 1936) (“The privilege of the owner of a possessory estate in fee simple defeasible to use the land is identical with that of an owner of a possessory estate in fee simple absolute, except that the privilege is limited by a duty not to commit waste.”). For example, as the Court held in Townsend, alienation would be inconsistent with the limitation.
The “limited fee” described in Townsend does not restrict use of the right of way to railroad purposes and would, therefore, resolve the first certified issue in favor of Union Pacific, at least with respect to the pre-1871 Acts, The California Court of Appeal and the district court, however, both relied on the later statement in Union Pacific that “[t]he most that thé ‘limited fee’ cases decided was that the railroads received all surface rights to the right of way and all rights incident to a use for railroad purposes.”
The Court in Union Pacific laid great emphasis on the nature of the claimed right: extraction of oil from the subsurface mineral, estate under the right of way. Accordingly, it was. not inappropriate for the Court to invoke the proviso in section 3 of the 1862 Act expressly excluding “mineral lands” from the grant. We disagree with the district court (and the California Court of Appeal) that “the railroad’s lease of the portions of the subsurface of the servient estate ,is a use essentially no different than the use of extracting oil and gas.”. In re SFPP Right-of-Way Claims,
A grant or reservation of minerals effects a horizontal severance of the rights in the land and creates two separate estates—one in the minerals and one in the surface. (‘‘Surface” is defined as the entire estate, including the subterranean estate, other than'the severed minerals.)
9 Richard R. Powell et al., Powell on Real Property § 63.06[2] (Michael Allan Wolf ed., 2017) (emphasis added).
By its terms, section 3’s proviso prevents the grantee from extracting mineral resources, not from üsing the subsurface for any other purpose. This is in keeping with the common law’s distinction between an ordinary easement (“a nonpossessory right to enter and use land”) and a profit á prendre (“an easement that confers the right to enter and remove timber, minerals, oil, gas, game, or other substances”).
We acknowledge that the Eighth and Tenth Circuits did not make the same distinction in the ETSI Cases. Both courts took Union Pacific’s reference to “surface rights” to refer to the physical surface of the land, to the exclusion of any rights in the subsurface. In our view, however, that reading was subsequently undermined by Brandt, which reaffirmed the longstanding consensus that the 1875 Act reflected a major shift in policy from the pre-1871 Acts. See
For these reasons, we hold that, while Union Pacific modified Townsend’s holding to stand only for the proposition that the railroads obtained at least the rights necessary to carry out railroad purposes under the pre-1871 Acts, it did not go further and hold that “railroad purposes” actually defined the outer limits of the grants. In other words, Union Pacific instructs us that Townsend does not control the result in this case, but does not itself tell us whether the pre-1871 Acts require a railroad purpose. ■
Instead, we find the answer in Brandt, which reaffirmed that the 1875 Act conveyed an interest different from that conveyed by the pre-1871 Acts. Because the landowners’ position would eliminate that difference, we hold that the pre-1871 Acts conferred a fee simple-defeasible in everything except the mineral estate. That interest entitles Union Pacific to lease the subsurface as well as the surface , of its right of way to SFPP as long as it continues to use the right of way to operate a railroad, regardless of whether the pipeline itself serves a “railroad purpose.”.
2. 1875 Act
Our answer to the first certified question does not make the second moot because Union Pacific concedes that the 1875 Act conferred only an easement in the right' of way, albeit & broad easement “for railroad purposes.” Union Pac.,
C. Can .the pipeline serve a railroad purpose?
Union Pacific did hot reference the pipeline’s ostensible railroad purpose in its original counterclaims. It did, however, seek leave to amend to add facts supporting the contention that it served such a purpose. The district court denied leave to amend as futile.
Union Pacific’s proposed amendment alleges that the pipeline serves a railroad purpose “because Union Pacific uses capacity on the pipeline to transport millions of gallons of fuel a year, purchased directly by Union Pacific from third-party refineries, via dedicated facilities to private terminals on the railroad line that Union Pacific owns.” It alleges that it “uses this fuel to power its locomotives,” and that the use of fuel from the pipeline “reducefs] core railroad operating costs by millions of dollars a year.” We hold that the district court should have granted leave to amend because that allegation, if proven, is sufficient to establish a prima facie case that the pipeline serves a railroad purpose.
It is beyond dispute that a railroad right of way confers more than a right to simply run trains over the land. See New Mexico v. U.S. Trust Co.,
[W]hile it must be admit[t]ed that a railroad company has the exclusive control of all the land within the lines of its roadway, and is not at liberty to alienate any part of it so as to interfere with the full exercise of the franchises granted, we are not prepared to assert that it may not license the erection of buildings for its convenience, even though they may be also for the convenience of others. It is not doubted that the [railroad] might have erected similar structures on the ground on which the plaintiffs’ buildings were placed, if in its judgment the structures were convenient for the receipt and delivery of freight on its road. Such erections would not have been inconsistent with the purposes for which its charter was granted. And, if the company might have put up the buildings, why might it not license others to do the same thing for the same object; namely, the increase of its facilities for the receipt and delivery of freight? The public is not injured, and it has no right to complain, so long as a free and safe passage is left for the carriage of freight and passengers.
Grand Trunk R.R. v. Richardson,
The district court reasoned that several factors took the pipeline outside the ambit
We are similarly unpersuaded by the district court’s conclusion that the incidental-use doctrine does not apply because the pipeline is operated by a third-party and for private gain. Grand Trunk makes it clear that a railroad may license third parties to do what it could do itself, even if the third party benefits in addition to the railroad. See
More fundamentally, Grand Trunk makes the sensible point that a railroad appurtenance has the same impact on the servient estate whether it is built by the railroad or a third party. Accord Mitchell,
We acknowledge that an appurtenance might be of such minimal or illusory benefit to railroad operations as to make the incidental-use doctrine inapplicable. For present purposes, it is sufficient to say that Union Pacific has plausibly alleged that the benefit it derives from the pipeline is sufficient for the doctrine to apply.
Ill
With respect to the first certified question, we hold that the pre-1871 Acts do not require a “railroad purpose.” With respect to the second, we hold that Union Pacific has plausibly alleged that the pipeline serves such a purpose. We therefore reverse the district court’s order granting the motion to dismiss Union Pacific’s counterclaims and remand with instructions to grant leave to amend.
REVERSED and REMANDED.
Notes
. Slow going on the westbound road enabled the Central Pacific to extend its road beyond the California border to the eventual meeting point at Promontory Summit, Utah Territory, where Leland Stanford famously drove the golden spike on May 10, 1869. See Act of July 2, 1864, ch. 216, § 16, 13 Stat. 356, 363 (authorizing the Central Pacific to extend its line 150 miles eastward from the California-Nevada border); Act of July 3, 1866, ch. 159, § 2, 14 Stat. 79, 80 (authorizing the Secretary of the Interior to approve further extensions of the Central Pacific line until it met with the Union Pacific line); Leo Sheep Co.,
. The right of way granted to the Central Pacific for its Portland branch was only 100 feet on each side of the road. See Act of July 25, 1866, § 3,
. In keeping with the parties’ practice, we refér to these cases collectively as the ETSI Cases.
. A small portion of Union Pacific's rights of way were acquired by private conveyance. See In re SFPP Right-of-Way Claims,
. The appellees further argue that Union Pacific has waived its arguments on the merits because it did not present them to the district court. While the record reflects that both sides argued extensively about collateral es-toppel, Union Pacific also challenged the merits of the state-court decision, calling it “wrong on the law” and in direct conflict with “longstanding Supreme Court precedent” in its written submissions. It also stated at oral argument that Union Pacific was distinguishable because "[m]ineral rights are different than subsurface rights.” The basis of the district court’s decision confirms that it understood Union Pacific to be arguing the merits.
. We express no opinion as to whether, on remand, the district court should return to the issue of collateral estoppel or how it should decide it. We would, of course, have jurisdiction to review its ruling in an appeal at the conclusion of the case.
. Although Union Pacific acquired rights of way under both the pre-1871 Acts and the 1875 Act, it does not provide any detail as to the proportion acquired under each act.
