    Jeffrey Memmer and the eleven other plaintiffs-appel-
    lants in this case (collectively, “Appellants” or “landown-
    ers”) own property in the state of Indiana. In February of
    2014, they brought suit in the United States Court of Fed-
    eral Claims, seeking compensation for an alleged taking
    arising from the operation of § 8(d) of the National Trails
    System Act Amendments of 1983 (“Trails Act”), 
    16 U.S.C. § 1247
    (d). 1 Appellants claimed that actions taken by the
    government on April 8, 2011, had permanently taken their
    property. According to Appellants, the taking arose out of
    the abandonment by Indiana Southwestern Railway Com-
    pany (“Indiana Southwestern”) of railway easements in In-
    diana in which Appellants had reversionary interests.
    Following a trial, the Court of Federal Claims found that
    1   The original complaint was filed by Mr. Memmer
    for himself and as representative of a class of similarly sit-
    uated individuals. Complaint, Memmer v. United States,
    No. 1:14-cv-00135-MMS (Fed. Cl. Feb. 18, 2014), ECF
    No. 1. In January of 2015, Mr. Memmer, joined by the
    other named Appellants, filed an amended complaint.
    Amended Complaint, Memmer v. United States, No. 1:14-
    cv-00135-MMS (Fed. Cl. Jan. 9, 2015), ECF No. 19.

    the United States had taken Appellants’ property. The
    court determined, however, that the taking lasted only
    from May 23, 2011, to January 7, 2014. Memmer v. United
    States, 
    150 Fed. Cl. 706
    , 761 (Nov. 2, 2020) (“Memmer I”).
    Following the court’s decision, and after the parties stipu-
    lated to compensation and interest, the court entered judg-
    ment in favor of Appellants. Judgment, Memmer v. United
    States, No. 1:14-cv-00135-MMS (Fed. Cl. June 7, 2021),
    ECF No. 198, J.A. 77.
    Appellants have appealed the ruling of the Court of
    Federal Claims that the taking by the United States lasted
    only from May 23, 2011, to January 7, 2014. For its part,
    the government has cross-appealed. It contends that the
    Court of Federal Claims erred in holding that Appellants’
    property was taken. In the alternative, the government ar-
    gues that, if there was a taking, it lasted only from May 23,
    2011, to November 8, 2013.
    For the reasons set forth below, we agree with the
    Court of Federal Claims that Appellants’ property was
    temporarily taken under the Trails Act. We agree with the
    government, however, that the taking lasted only from
    May 23, 2011, to November 8, 2013. Accordingly, we af-
    firm-in-part and vacate-in-part. The case is remanded to
    the Court of Federal Claims for a determination as to the
    compensation and interest to which Appellants are entitled
    as a result of the taking of their property having ended on
    November 8, 2013, rather than on January 7, 2014.
    BACKGROUND
    I
    A rail carrier that intends to abandon or discontinue a
    rail line must either file an application with, or seek ex-
    emption from, the Surface Transportation Board (“STB” or
    “Board”). The STB has authority to regulate the construc-
    tion, operation, and abandonment of most rail lines in the
    United States. 
    49 U.S.C. §§ 10903
    , 10502; 49 C.F.R.
    Case: 21-2133     Document: 54     Page: 4    Filed: 09/28/2022
    4                                              MEMMER    v. US
    §§ 1152.20–1152.22, 1152.50; Caldwell v. United States,
    
    391 F.3d 1226
    , 1228 (Fed. Cir. 2004). At the same time,
    Congress has determined it beneficial to preserve estab-
    lished railroad rights-of-way and to create recreational
    trails. Accordingly, § 8(d) of the Trails Act, 
    16 U.S.C. § 1247
    (d), provides a mechanism for a rail carrier that in-
    tends to abandon or discontinue a rail line to instead nego-
    tiate an agreement with a locality or a private entity trail
    sponsor to convert the railroad’s right-of-way into a recre-
    ational trail. 2
    If a rail carrier has sought an abandonment exemption
    and agrees to negotiate an agreement with a trail sponsor,
    the STB will issue a Notice of Interim Trail Use or Aban-
    donment (“NITU”). The NITU provides for a negotiation
    period during which the railroad can “discontinue service”
    on the rail line and “salvage track and materials.”
    
    49 C.F.R. § 1152.29
    (d)(1) (2012) (providing a negotiation
    period of 180 days); Preseault v. Interstate Com. Comm’n,
    
    494 U.S. 1
    , 7 & n.5 (1990) (discussing the 180-day negotia-
    tion period following the issuance of a NITU by the Inter-
    state Commerce Commission, the predecessor to the STB). 3
    2   An alternate means of preventing the abandon-
    ment of a rail line is through another party’s offer to subsi-
    dize the rail line that is the subject of an abandonment
    application. This is referred to as an Offer of Financial As-
    sistance, or “OFA.” See 
    49 U.S.C. § 10904
    .
    3   If a railroad that has applied for abandonment
    without seeking an exemption agrees to negotiate a trail-
    use agreement, the railroad may apply to the STB for a
    Certificate of Interim Trail Use or Abandonment (“CITU”).
    
    49 C.F.R. § 1152.29
    (c)(1) (2012). Section 1552.29 of Title
    49 has changed and currently provides that a railroad may
    fully abandon the line if no interim trail-use agreement is
    reached within one year of the issuance of the NITU or
    CITU. See 
    49 C.F.R. § 1552.29
    (c),(d) (2020).
    Case: 21-2133     Document: 54      Page: 5    Filed: 09/28/2022
    MEMMER   v. US                                               5
    After the negotiation period, if no agreement is reached,
    the railroad may abandon the line and file a notice of con-
    summation of abandonment with the Board. 
    49 C.F.R. § 1152.29
    (d)(1), (e)(2). If an agreement is reached, trail use
    of the right-of-way is authorized and abandonment by the
    railroad is blocked indefinitely, subject to restoration of the
    right-of-way for railroad purposes. Castillo v. United
    States, 
    952 F.3d 1311
    , 1315 (Fed. Cir. 2020); see also 
    16 U.S.C. § 1247
    (d). Because the right-of-way may be re-
    stored for railroad purposes, the process contemplated by
    the Trails Act is referred to as “railbanking.” See Caldwell,
    
    391 F.3d at 1229
    .
    Where the railroad held an easement to the underlying
    property, the conversion of the right-of-way to a recrea-
    tional trail, and thus the implementation of a new ease-
    ment, can form the basis for a physical takings claim under
    the Fifth Amendment to the Constitution. Preseault v.
    United States, 
    100 F.3d 1525
    , 1550 (Fed. Cir. 1996) (en
    banc) (“Presault II”). Such a taking occurs when “state law
    reversionary property interests that would otherwise vest
    in the adjacent landowners are blocked from so vesting.”
    Caldwell, 
    391 F.3d at 1233
    . We have explained that the
    taking begins upon the issuance of the NITU, “the only gov-
    ernment action in the railbanking process that operates to
    prevent abandonment of the corridor and to preclude the
    vesting of state law reversionary interests in the right-of-
    way.” 
    Id.
     at 1233–34, 1236; see also Barclay v. United
    States, 
    443 F.3d 1368
    , 1373 (Fed. Cir. 2006).
    In Ladd v. United States, 
    630 F.3d 1015
    , 1023–24 (Fed.
    Cir. 2010), we held that where no trail-use agreement is
    reached, but the NITU compels the railroad to delay its
    abandonment, the issuance of a NITU can effect a tempo-
    rary physical taking. In Caquelin v. United States, 
    959 F.3d 1360
     (Fed. Cir. 2020) (“Caquelin III”), we clarified and
    explained whether the issuance of a NITU alone can trig-
    ger a taking. The Caquelin III court clarified the legal
    standard for ‘‘the timing of a NITU-based taking’’ and the
    Case: 21-2133     Document: 54      Page: 6    Filed: 09/28/2022
    6                                               MEMMER    v. US
    application of general causation principles under Caldwell,
    Barclay, and Ladd. 959 F.3d at 1370–71. The court ex-
    plained that, because a railroad’s easement would remain
    in place absent abandonment by the railroad, there could
    be no taking until the time as of which, had there been no
    NITU, the railroad would have abandoned the rail line. See
    id. at 1371–72. In other words, ‘‘a NITU does not effect a
    taking if, even in the absence of a NITU, the railroad would
    not have abandoned its line (a necessary prerequisite for
    termination of the easement under state law) during the
    period of the NITU.’’ Id. at 1363. ‘‘[I]n such a case, the
    NITU takes nothing from the landowner that the land-
    owner would have had in the absence of the NITU.’’ Id.
    II
    On October 25, 2010, Indiana Southwestern submitted
    a notice of exemption from abandonment proceedings, stat-
    ing that it would consummate abandonment of its rail lines
    on or after January 15, 2011. Memmer I, 150 Fed. Cl. at
    748; J.A. 253–54, 1253–57, 1358–61. In response, on No-
    vember 12, 2010, the STB published a notice stating that,
    absent third party intervention, the exemption would be
    effective, and thus, Indiana Southwestern could abandon
    the lines, on December 14, 2010. 4 
    75 Fed. Reg. 69,520
     (Nov.
    12, 2010). The STB’s notice indicated that the deadline for
    railbanking requests and OFAs was November 22, 2010.
    
    Id.
     Pursuant to 
    49 C.F.R. § 1152.29
    (e)(2), Indiana South-
    western was given one year from the STB’s notice, until
    November 12, 2011, to file a notice of consummation of
    abandonment, if it chose to do so.
    A few days after the STB’s notice was published, the
    Indiana Trails Fund, Inc. (“Trails Fund”) submitted a re-
    quest for the Board to issue a NITU for the rail corridor to
    4  We hereafter sometimes refer to Indiana South-
    western’s rail lines collectively as the “rail line” or “line.”
    Case: 21-2133     Document: 54     Page: 7    Filed: 09/28/2022
    MEMMER   v. US                                              7
    permit negotiations about railbanking if Indiana South-
    western agreed. J.A. 254. The Board also received notice
    from the Town of Poseyville, Indiana of its intent to file an
    OFA.
    On November 23, 2010, Indiana Southwestern advised
    that it was “willing to negotiate interim trail use/rail bank-
    ing with . . . the Indiana Trails Fund, Inc.” Suppl. App. 1. 5
    The Town of Poseyville’s OFA, however, took priority over
    the railbanking request, and there were several months of
    proceedings over the town’s offer. Memmer I, 150 Fed. Cl.
    at 733–34. Ultimately, the Poseyville offer fell through.
    Thereafter, with the railroad’s consent, on April 8,
    2011, the Board issued a NITU that became effective May
    23, 2011. Id. at 734, 751; J.A. 254, 1362–69. The NITU
    provided a 180-day period for the Trails Fund and Indiana
    Southwestern to negotiate an interim trail-use agreement,
    through November 19, 2011. J.A. 1368–69. The Trails
    Fund obtained four extensions—all with the consent of In-
    diana Southwestern—through November 8, 2013. Id. at
    254–55, 1075, 1370–73. While the NITU was pending, In-
    diana Southwestern executed a contract with A&K Mate-
    rials, Inc. (“A&K”). Pursuant to that contract, A&K agreed
    to purchase and remove the rails on the rail line except
    those in rail crossings. Memmer I, 150 Fed. Cl. at 735, 748.
    It also agreed to move the ties from the center of the rail
    line. Id. A&K complied with the terms of the agreement
    and completed its work by early February of 2012.
    The NITU deadline lapsed, and the NITU therefore ex-
    pired, without the Trails Fund and Indiana Southwestern
    executing a trail-use agreement. Because the NITU exten-
    sions had lasted more than one year, under 49 C.F.R.

    mental Appendix filed as an addendum to the United
    States’ Opening Brief.
    Case: 21-2133    Document: 54      Page: 8   Filed: 09/28/2022

    § 1152.29(e)(2), Indiana Southwestern then had 60 days—
    through January 7, 2014—to file a notice of consummation
    of abandonment of the rail line. It chose not to do so, how-
    ever. See J.A. 1077, 1214, 1229.
    Eventually, Indiana Southwestern submitted a new
    notice of exemption. In response, the STB published a no-
    tice in July of 2021, shortly after this appeal was filed.
    
    86 Fed. Reg. 37,782
     (July 16, 2021). The STB’s notice
    stated that, absent third party intervention by July 26,
    2021, the exemption would be effective, and thus Indiana
    Southwestern could abandon the line, on August 15, 2021.
    No potential trail sponsors came forward, and no NITU is-
    sued. Indiana Southwestern then filed a notice of consum-
    mation with the Board on August 31, 2021, meaning that
    the rail line was officially abandoned. As a result, Indiana
    Southwestern’s easements terminated, and the landown-
    ers’ fee simple interests became unencumbered by any
    easements.
    III
    On January 9, 2015, the landowners filed their
    amended complaint, asserting that the issuance of the
    NITU on April 8, 2011, effected a permanent Fifth Amend-
    ment taking of their property. The landowners alleged that
    they each owned their property in fee simple; that Indiana
    Southwestern owned an easement across each of their
    properties; that their properties would no longer be bur-
    dened by that easement if the easement was abandoned or
    authorized for use beyond its scope; and that, but for the
    issuance of the NITU, they would own their land unencum-
    bered by any easements. Memmer I, 150 Fed. Cl. at
    716–17.
    The parties each moved for summary judgment on lia-
    bility. Relevant to this appeal, the parties disputed
    whether the issuance of the NITU effected a taking when a
    trail-use agreement was not executed, the NITU expired on
    its own terms, and Indiana Southwestern did not
    Case: 21-2133     Document: 54     Page: 9    Filed: 09/28/2022
    MEMMER   v. US                                             9
    consummate abandonment of its rail line during the period
    of the NITU. Id. at 717.
    In an Opinion and Order issued July 10, 2015, the
    Court of Federal Claims held that the NITU effected a tem-
    porary categorical taking that spanned from May 23, 2011,
    the date the NITU went into effect, to November 8, 2013,
    the date the NITU expired. 6 Id. The parties ultimately
    reached a settlement on the amount due for the claims that
    survived summary judgment, and each appealed different
    facets of the court’s Opinion and Order to this court. Id. at
    717–18.
    While the case was on appeal, our court issued a pre-
    decessor decision to Caquelin III, Caquelin v. United
    States, 697 F. App’x 1016 (Fed. Cir. 2017) (“Caquelin I”).
    In that case, the government argued for the application of
    a multi-factor takings analysis pursuant to Penn Central
    Transportation Co. v. City of New York, 
    438 U.S. 104
    , 124
    (1978), and Arkansas Game & Fish Commission v. United
    States, 
    568 U.S. 23
    , 38–40 (2012), instead of a categorical
    takings analysis. Our court’s Caquelin I decision re-
    manded for a decision by the Court of Federal Claims to
    create in that case “a fully developed record applying the
    multi-factor analysis the government urge[d].” Caquelin I,
    697 F. App’x at 1020. The parties in this case then jointly
    sought, and our court granted, a remand consistent with
    the ruling in Caquelin I. Memmer I, 150 Fed. Cl. at 718.
    Subsequently, the Court of Federal Claims issued its deci-
    sion on remand in Caquelin, Caquelin v. United States,
    
    140 Fed. Cl. 564
     (“Caquelin II”), setting forth the Court of
    6   A categorical taking occurs when a regulation
    “compel[s a] property owner to suffer a physical invasion”
    or “denies all economically beneficial or productive use” of
    the property. Lucas v. S.C. Coastal Council, 
    505 U.S. 1003
    ,
    1015 (1992) (internal quotation marks omitted).

    Federal Claims’ multi-factor analysis. Id. at 584. Our
    court then issued Caquelin III, which reaffirmed that a
    taking under the Trails Act is a categorical taking and clar-
    ified the applicable causation standard, as discussed above.
    959 F.3d at 1367–73. Caquelin III issued before the issu-
    ance of the decision presently on appeal.
    On remand in this case, the Court of Federal Claims
    allowed additional discovery and conducted a trial on lia-
    bility and damages. With the benefit of the issuance of our
    Caquelin III decision before it, the court understood that it
    needed to analyze “whether the Board’s issuance of the
    NITU caused the injury alleged by [the landowners]—a
    compelled continuation of Indiana Southwestern’s ease-
    ments that prevented [the landowners] from acquiring fee
    simple interests in the underlying land by operation of
    state law.” Memmer I, 150 Fed. Cl. at 747. Before the
    Court of Federal Claims, the government argued that the
    landowners suffered no injury because they were in the
    same position they were in before Indiana Southwestern
    filed its notice of exemption. Id. The landowners con-
    tended that they were injured by the Board’s issuance of
    the NITU—at least while the NITU was in effect—because
    a NITU automatically causes a taking under binding prec-
    edent. Id. at 747–48.
    In its decision, the Court of Federal Claims determined
    that the landowners had established that Indiana South-
    western would have abandoned the rail lines in the absence
    of the NITU. Id. at 748. The court relied on the fact that
    Indiana Southwestern initiated the process for abandon-
    ment by filing a notice of exemption in which it represented
    that it had no local traffic move over its lines for at least
    the preceding two years and averred that it would consum-
    mate the abandonment of the lines “on or after January 15,
    2011.” Id. (quoting J.A. 1254). The court also relied on the
    fact that, during the pendency of the NITU, Indiana South-
    western engaged A&K to remove the rails on the line. Id.
    In addition, the court noted, counsel for Indiana

    Southwestern testified that, even after the NITU expired,
    it was Indiana Southwestern’s intent to either finalize the
    abandonment or execute a trail-use agreement. Id. at 748;
    see J.A. 1196–98, 1228–29. The court concluded:
    These facts reflect that Indiana Southwestern had
    every intent to abandon the railroad lines during
    the period of time that the NITU was in effect, and
    was prevented from doing so by the existence of the
    NITU. Further, the only evidence possibly suggest-
    ing that Indiana Southwestern might not have
    abandoned the lines between May 23, 2011, and
    November 8, 2013, is the fact that it did not file a
    notice of consummation within the sixty-day period
    following the expiration of the NITU, as legally re-
    quired. However, what Indiana Southwestern
    chose to do (or not do) after the NITU expired is not
    particularly suggestive of what Indiana Southwest-
    ern was planning to do while the NITU was in place
    because such action (or inaction) might have been
    prompted by information learned or circumstances
    that arose after the NITU expired. And even if it
    was suggestive, it is outweighed by the evidence
    demonstrating Indiana Southwestern’s intent to
    abandon the lines. Accordingly, the Board’s issu-
    ance of the NITU injured plaintiffs by compelling
    the continuation of Indiana Southwestern’s ease-
    ments––despite Indiana Southwestern’s expressed
    intent to abandon the lines––and preventing them
    from acquiring fee simple interests in the underly-
    ing land.

    ing that the railroad continued to negotiate a trail-use

    was irrelevant to whether it would have abandoned the rail
    lines during the pendency of the NITU. Id. at 748 n.41.
    The Court of Federal Claims then examined the scope
    and duration of the taking. Id. at 750–52. The court re-
    jected the landowners’ argument that the taking was per-
    manent. Instead, the court determined, the taking was
    temporary, lasting from the date the NITU became effec-
    tive—May 23, 2011—through the deadline under 
    49 C.F.R. § 1152.29
    (e)(2) for Indiana Southwestern to file its notice
    of consummation of abandonment—January 7, 2014.

    II
    We turn first to the government’s cross-appeal, which
    challenges the Court of Federal Claims’ conclusion that the
    issuance of the NITU in this case effected a taking. Accord-
    ing to the government, “there is no change to the
    Case: 21-2133     Document: 54      Page: 13     Filed: 09/28/2022
    MEMMER   v. US                                                13
    landowners’ property interests,” and therefore no taking,
    “when a railroad requests abandonment authority from the
    Board and then [the railroad] chooses not to exercise that
    authority,” as Indiana Southwestern did in this case.
    United States Opening Br. 33.
    The government urges that our cases have found a tak-
    ing to have occurred only where the NITU either (a) re-
    sulted in a trail-use agreement; or (b) compelled a delay in
    the railroad’s abandonment of its line. 
    Id.
     at 20–26, 30–36.
    “[W]hen a NITU expires with no change in the use of the
    rail corridor or in federal jurisdiction over the rail line,” the
    government contends, it “cannot be said to have caused a
    change in the nature or effect of any easement.” Id. at 33.
    The government also urges that in a situation “when the
    railroad does not abandon the line and easements do not
    terminate after the NITU period, no government action . . .
    can be said to have caused a delay,” and therefore no tem-
    porary taking has occurred, because “[t]he government
    cannot delay something that does not happen.” Id. at 34.
    Relatedly, the government contends that the Court of
    Federal Claims erred when it held that the Caquelin III
    causation standard was met, i.e., that Indiana Southwest-
    ern would have abandoned the rail line if the NITU had not
    issued. Id. at 36–42. The government points to Indiana
    Southwestern’s decisions to participate in negotiations
    with a potential trail sponsor and to extend the NITU and
    argues that these actions show the railroad’s interest in
    pursuing a rail-trail as opposed to an interest in abandon-
    ing the rail corridor. Id. at 37–39. The government also
    points to Indiana Southwestern’s decision not to consum-
    mate abandonment after the NITU expired, urging that it
    “should weigh heavily against the conclusion that the
    NITU caused a physical taking solely by preventing the
    railroad from abandoning the line during its pendency.” Id.
    at 39. The government posits that, in this case, Indiana
    Southwestern “simply exercised its discretion—as it
    Case: 21-2133    Document: 54      Page: 14    Filed: 09/28/2022

    always may—to not finish the regulatory process that it be-
    gan.” Id. at 20.
    Appellants respond that “the evidence of causation in
    this case is substantial, overwhelming, and unrefuted and
    far exceeds the nature of the evidence that established cau-
    sation in [Caquelin III].” Appellants’ Resp. & Reply Br. 3;
    see also id. at 2–3, 4–9. Appellants argue that, in Caquelin
    III, our court considered, and found sufficient to determine
    that Ms. Caquelin had met her burden on the causation is-
    sue, evidence of the railroad’s actions before the NITU (“the
    railroad filed an application to abandon, indicating an af-
    firmative intent to abandon”); evidence of its actions during
    the NITU (the railroad “refused [to consent to an extension
    of the NITU], confirming an interest in abandoning sooner
    rather than later” and removed track during the NITU);
    and evidence of its actions after the NITU (the railroad
    “completed the abandonment just three months after . . .
    the date . . . it became legally authorized to abandon the
    line”)). Id. at 11–12 (citing Caquelin III, 959 F.3d at 1372–
    73). Appellants also point out that the Caquelin III court
    considered that the railroad in that case fulfilled the stand-
    ard of abandonment under state law. Id. at 12.
    The evidence of causation in this case that Appellants
    point to is evidence that Indiana Southwestern intended to
    consummate abandonment when it submitted its notice of
    exemption before the NITU issued, evidence that the rail-
    road removed the rails and ties during the pendency of the
    NITU (which, Appellants argue, established abandonment
    under Indiana state law), and evidence that the railroad
    still intended to either consummate abandonment or enter
    into a trail-use agreement when the NITU expired, and ul-
    timately did formally consummate abandonment under
    federal law in 2021. Id. at 12–15 (citing J.A. 1216, 1221,
    1228–29).

    III
    To begin, we disagree with the government that a phys-
    ical taking cannot occur when a NITU ends without either
    a trail-use agreement or the consummation of the rail-
    road’s abandonment. As we stated in Caquelin III:
    The NITU in this case, as in similar cases, was a
    government action that compelled continuation of
    an easement for a time; it did so intentionally and
    with specific identification of the land at issue; and
    it did so solely for the purpose of seeking to ar-
    range, without the landowner’s consent, to con-
    tinue the easement for still longer, indeed
    indefinitely, by an actual trail conversion.
    Caquelin III, 959 F.3d at 1367. Thus, once initiated, a
    NITU can effect a “mandated continuation” of an easement
    by the STB that “provid[es] a right of occupation by some-
    one other than the landowner and . . . bar[s] the landowner
    from using the ground burdened by the easement.” Id.; see
    also Ladd, 630 F.3d at 1025; Caldwell, 
    391 F.3d at 1234, 1236
    . This “mandated” or “compelled” continuation of an
    easement can occur regardless of whether the NITU ulti-
    mately leads to a trail-use agreement or the railroad’s
    abandonment is ultimately consummated. That said, as
    we explained in Caquelin III, in order to determine if a
    NITU has effected a taking, we must consider whether the
    railroad would have abandoned the line, i.e., relinquished
    its rights to the rail right-of-way, during the period of the
    NITU had there been no NITU. 959 F.3d at 1372. That
    brings us to the matter of causation in this case. In that
    regard, we are not persuaded by the government’s argu-
    ment that the Court of Federal Claims erred in its causa-
    tion analysis.
    Significantly, the government does not argue that the
    court’s findings of fact on causation are clearly erroneous.

    21-2133_06062022.mp3. What this means is that, in order
    for us to reverse the Court of Federal Claims on causation,
    we would have to conclude that the facts found by the court
    are insufficient support for the finding that “Indiana
    Southwestern had every intent to abandon the railroad
    lines during the period of time that the NITU was in effect,
    and was prevented from doing so by the existence of the
    NITU.” Memmer I, 150 Fed. Cl. at 748; see Caquelin III,
    959 F.3d at 1372–73 (rejecting the government’s argument
    that the evidence was insufficient to support a finding of
    causation where there was no evidence indicating the rail-
    road would have delayed abandonment had there been no
    NITU). We are unable to reach that conclusion, however.
    Since it does not challenge the Court of Federal Claims’
    findings of fact, the government relies heavily on evidence
    that Indiana Southwestern was interested in entering into
    a trail-use agreement as showing that the railroad did not
    intend to abandon the rail line during the NITU period. We
    fail to see, though, how this evidence helps the government
    when, had a trail-use agreement been reached during the
    NITU, a taking of Appellants’ property would have oc-
    curred. See Presault II, 
    100 F.3d at 1550
     (holding that the
    conversion of a rail line to a public trail was a taking of a
    new easement for which the landowners were entitled to
    compensation). Moreover, the government does not point
    to any evidence indicating that Indiana Southwestern had
    changed its mind and wished to continue operating the rail
    line during the NITU period. We therefore cannot say that
    the Court of Federal Claims erred in finding the evidence
    that Indiana Southwestern would have relinquished its
    rights to its right-of-way during the NITU period out-
    weighed the evidence to the contrary.
    IV
    We turn next to the issue of when the temporary taking
    ended. Appellants urge us to hold that the taking lasted
    until   Indiana      Southwestern      consummated      its
    Case: 21-2133     Document: 54    Page: 17    Filed: 09/28/2022

    abandonment on August 31, 2021. Appellants’ Br. 2, 5, 38–
    41, 44–52. This is so, Appellants contend, because the re-
    quirements for abandonment under Indiana law were sat-
    isfied upon the railroad’s removal of the rails, yet
    Appellants’ reversionary rights were still blocked until the
    railroad filed a notice of consummation of abandonment as
    required by 
    49 C.F.R. § 1152.29
    (e)(2). 
    Id. at 41
    ; Appellants’
    Resp. & Reply Br. 24–26.
    For its part, the government contends that, if we agree
    with the Court of Federal Claims that a taking occurred,
    we nevertheless should hold that the court erred when it
    held that the taking ended on January 7, 2014, the conclu-
    sion of the 60-day period following expiration of the NITU.
    It was during that period that Indiana Southwestern could
    have filed a notice of consummation of abandonment had it
    chosen to do so. Instead, the government argues, the tak-
    ing ended when the NITU expired on November 8, 2013,
    because after that date, the decision to fully abandon the
    rail line, and thus the continuation or non-continuation of
    the easement, was solely in the control of Indiana South-
    western. The government responds to Appellants’ argu-
    ments regarding Indiana law by pointing out that the STB
    has exclusive and plenary jurisdiction over the abandon-
    ment of rail lines, and that abandonment under state law
    is preempted by federal law. United States Opening Br.

    V
    We agree with the government that the taking ended
    upon expiration of the NITU on November 8, 2013. This is
    so because it was on that date that the United States was
    no longer responsible for mandating the continuation of the
    easement because, from that point forward, the decision
    rested solely in the hands of Indiana Southwestern. Nav-
    ajo Nation v. United States, 
    631 F.3d 1268
    , 1274 (Fed. Cir.
    Case: 21-2133    Document: 54      Page: 18    Filed: 09/28/2022
    18                                             MEMMER    v. US
    2011) (“A takings claim must be predicated on actions un-
    dertaken by the United States . . . .”).
    For the same reason, we reject Appellants’ argument
    that the taking lasted until August 31, 2021, when Indiana
    Southwestern finally filed its notice of consummation of
    abandonment pursuant to 
    49 C.F.R. § 1152.29
    (e)(2). Ap-
    pellants claim that § 1152.29(e)(2) effected a taking be-
    cause it allowed the railroad to fail to consummate
    abandonment after state law abandonment had already oc-
    curred. In other words, Appellants argue that, because
    § 1152.29(e)(2) requires the filing of a notice of consumma-
    tion of abandonment, but does not mandate the filing of
    that notice as of the date state law abandonment require-
    ments are met, the regulation had the effect in this case of
    extending Indiana Southwestern’s easements and there-
    fore the taking of Appellants’ property, for an additional
    period. 7   We reject this argument.          As Appellants
    acknowledge, “it is always the railroad’s choice that ulti-
    mately impacts the duration of the taking.” Appellants’
    Resp. & Reply Br. 26. Moreover, acceptance of Appellants’
    7   Paragraph (e)(2) of 
    49 C.F.R. § 1152.29
     states that
    a railroad that has received authority from the STB to
    abandon a rail line “shall file a notice of consummation
    with the Board to signify that it has exercised the authority
    granted and fully abandoned the line (e.g., discontinued op-
    erations, salvaged the track, canceled tariffs, and intends
    that the property be removed from the interstate rail net-
    work).” 
    49 C.F.R. § 1152.29
    (e)(2). The regulation provides
    that, “assuming that the railroad intends to consummate
    the abandonment,” the notice of consummation must be
    filed within one year of the service date of the decision per-
    mitting the abandonment unless at the conclusion of the
    one-year period a legal or regulatory barrier exists, in
    which case the notice of consummation must be filed no
    later than 60 days after the barrier is removed.

    argument would effectively contradict the STB’s plenary
    authority to regulate abandonment, which Congress
    granted over a hundred years ago in the Transportation
    Act of 1920, 
    Pub. L. No. 66-162, 41
     Stat. 456, 477–78 (“[N]o
    carrier by railroad subject to this Act shall abandon all or
    any portion of a line of railroad, or the operation thereof,
    unless and until there shall first have been obtained from
    the Commission a certificate that the present or future
    public convenience and necessity permit of such abandon-
    ment.”).
    CONCLUSION
    For the foregoing reasons, we hold that the Court of
    Federal Claims did not err in finding that Appellants suf-
    fered a temporary taking of their property. We hold that
    the court did err, however, in finding that the taking lasted
    until January 7, 2014. As explained, it lasted only until
    November 8, 2013. We therefore affirm the Court of Fed-
    eral Claims’ determination on liability, but we vacate its
    ultimate judgment as to compensation and interest. We
    remand the case to the court for a determination of the
    compensation and interest to which Appellants are entitled
    as a result of the taking of their property having ended on
    November 8, 2013, rather than on January 7, 2014.
