    antitrust actions that gave rise to the certified questions, freight
    shippers (“Plaintiffs”) allege that the nation’s four largest
    freight railroads (“Defendants” or “Railroads”) have violated
    the Sherman Act, 
    15 U.S.C. § 1
    , by “engag[ing] in a price-
    fixing conspiracy to coordinate their fuel surcharge programs
    as a means to impose supra-competitive total price increases on
    their shipping customers.” In re Rail Freight Fuel Surcharge
    Antitrust Litig., 
    520 F. Supp. 3d 1
    , 8 (D.D.C. 2021) (citation
    omitted). Before hearing summary judgment motions, the
    District Court considered Defendants’ motions to exclude
    certain evidence on which Plaintiffs rely. Defendants argued
    the challenged documents were inadmissible under 
    49 U.S.C. § 10706
    (a)(3)(B)(ii)(II) (“Section 10706”) as evidence of the
    Railroads’ discussions or agreements concerning “interline”
    traffic.
    Interline movements are shipments carried along two or
    more railroads’ tracks under a common arrangement. Section
    10706 states that “[i]n any proceeding” in which rail carriers
    are alleged to have violated antitrust laws, conspiracy “may not
    be inferred from evidence that two or more rail carriers acted
    together with respect to an interline rate or related matter and
    that a party to such action took similar action with respect to a
    rate or related matter on another route or traffic.” 
    49 U.S.C. § 10706
    (a)(3)(B)(ii). The statute tellingly provides that
    “evidence of a discussion or agreement between or among” rail
    carriers “shall not be admissible if the discussion or agreement
    . . . concerned an interline movement of the rail carrier,” and
    “would not, considered by itself, violate the [antitrust] laws.”
    
    Id.
     § 10706(a)(3)(B)(ii)(II) (emphasis added).
    The parties sharply disagreed over whether and how the
    rule of evidence under Section 10706 should be applied to the
    documents cited by Defendants in their motions to exclude
    evidence. As relevant here, the District Court held that “to be
    4
    protected by the statute, an interline movement must be an
    identifiable movement or movements with identifiable
    circumstances, such as a specific shipper, specific shipments,
    and specific destinations,” 520 F. Supp. 3d at 29; and it further
    held that a discussion or agreement does not “concern”
    interline movements if it could also be said to concern other
    types of rail freight movements, id. at 33. The District Court
    denied “[D]efendants’ motion for the exclusion of exhibits as a
    whole,” id. at 34, and thus effectively denied full protection to
    the contested documents cited by Defendants. Instead, the
    District Court indicated that Defendants could “propose
    redactions to remove [from documents] discussions or
    agreements that concerned an interline movement of the rail
    carrier, and, where redaction is impracticable or not feasible,
    may request a suitable limiting instruction.” Id.
    Defendants then asked the District Court to certify its order
    for interlocutory appeal under 
    28 U.S.C. § 1292
    (b). The
    District Court agreed after finding that the “order involves a
    controlling question of law as to which there is substantial
    ground for difference of opinion and . . . an immediate appeal
    from the order may materially advance the ultimate termination
    of the litigation.” Id.; see In re Rail Freight Fuel Surcharge
    Antitrust Litig., 
    2021 WL 2433737
    , at *4-6 (D.D.C. June 15,
    2021). This court, “in its discretion,” permitted the appeal
    under § 1292(b).
    In pressing for interlocutory review, Defendants focused
    on two aspects of the District Court’s judgment: “(1) that the
    phrase ‘an interline movement’ in Section 10706 means that
    the statutory protections apply only to discussions or
    agreements about ‘identifiable . . . movements with identifiable
    circumstances, such as a specific shipper, specific shipments,
    and specific destinations,’ and (2) that courts may implement
    the protections of Section 10706 through redactions and
    5
    limiting instructions.” 
    2021 WL 2433737
    , at *3 (omission in
    original) (internal quotation marks and citation omitted). In the
    opinion that follows below, we will focus on these two
    principal issues and related matters. Because we find that the
    District Court’s interpretation of Section 10706 sometimes
    strays from the literal terms of the statute, we affirm in part and
    reverse in part. Accordingly, we vacate the District Court’s
    order and remand for the court to reconsider the evidence at
    issue consistent with this court’s interpretation of Section
    10706.
    I. BACKGROUND
    A. Statutory Framework
    Congress enacted the Section 10706 statutory rule of
    evidence as part of the Staggers Rail Act of 1980, Pub. L. No.
    96-448, 
    94 Stat. 1895
     (“Act”). The Act’s “primary goal” “was
    to revitalize the railroad industry by reducing or eliminating
    regulatory burdens.” Coal Exps. Ass’n of the U.S., Inc. v.
    United States, 
    745 F.2d 76
    , 80-81 (D.C. Cir. 1984). “[T]he
    underlying approach of the legislation was to move toward
    much greater reliance on market forces rather than regulation
    to govern rail carriage, but to temper that move with a policy
    of retaining regulation where the market would be insufficient
    to protect shippers and the public from abusive railroad
    practices.” 
    Id. at 81
    .
    Rail freight traffic involves two types of movements:
    interline and single-line. Br. for the United States and the
    Federal Trade Commission (“FTC”) as Amici Curiae in
    Support of Pls.-Appellees and Affirmance 1, 11. As explained
    above, interline movements are shipments carried along two or
    more railroads’ tracks under a common arrangement. Id. at 1.
    In contrast, single-line shipments are moved by one carrier on
    6
    its own tracks. Id. Outside of their shared interline traffic, rail
    carriers generally compete with one another. See id.
    “Facilitating interline traffic requires coordination among
    competing freight railroads over logistics and shipping rates.”
    In re Rail Freight Fuel Surcharge Antitrust Litig.–MDL No.
    1869, 
    725 F.3d 244
    , 247 n.1 (D.C. Cir. 2013). Therefore, as
    noted above, Section 10706 provides that proof of a conspiracy
    “may not be inferred from evidence that two or more rail
    carriers acted together with respect to an interline rate or related
    matter and that a party to such action took similar action with
    respect to a rate or related matter on another route or traffic.”
    
    49 U.S.C. § 10706
    (a)(3)(B)(ii). In addition to the bar against
    impermissible inferences, Section 10706 also precludes the
    admission of evidence of certain discussions and agreements
    between rail carriers. In relevant part, this statutory rule of
    evidence states:
    In any proceeding in which [an antitrust] violation is
    alleged, evidence of a discussion or agreement between
    or among such rail carrier and one or more other rail
    carriers, or of any rate or other action resulting from
    such discussion or agreement, shall not be admissible if
    the discussion or agreement—
    ...
    (II) concerned an interline movement of the rail
    carrier, and the discussion or agreement would
    not, considered by itself, violate the [antitrust]
    laws . . . .
    In any proceeding before a jury, the court shall
    determine whether the requirements of [this subclause]
    are satisfied before allowing the introduction of any
    such evidence.

    B. Facts and Procedural History
    Defendants BNSF Railway Co. (“BNSF”), CSX
    Transportation, Inc., Norfolk Southern Railway Co., and Union
    Pacific Railroad Co. (“Union Pacific”) account for the majority
    of rail freight traffic in the United States. In re Rail Freight
    Fuel Surcharge Antitrust Litig., 725 F.3d at 247. “In some
    regions, the railroads’ networks overlap. In others, tracks may
    belong almost exclusively to a single railroad.” Id. Each of the
    Defendants interlines traffic with the others. See id.; Opening
    Br. of Appellants 4.
    The instant actions concern Plaintiffs’ challenges to rate-
    based fuel surcharges that the Railroads imposed on shipments.
    In re Rail Freight Fuel Surcharge Antitrust Litig., 725 F.3d at
    247-48. As we have previously explained:
    To offset fuel costs, freight railroads often include
    fuel surcharges on top of the base rates they charge their
    customers. These fuel surcharges have traditionally
    taken two forms. Mileage-based fuel surcharges raise
    total rates in proportion to shipping distances. Rate-
    based fuel surcharges, by contrast, depend on a
    prearranged “strike” or “trigger” price. When fuel
    prices are below the trigger price, no fuel surcharge
    supplements the base rate. But once fuel prices exceed
    the trigger price, a surcharge is imposed as a function
    of the base rate. . . .
    Rate-based fuel surcharges were not unheard of at
    the start of the new millennium, but neither were they
    the norm. That all changed by the mid–2000s, when
    8
    fuel surcharge provisions became ubiquitous,
    governing the vast majority of the [D]efendants’
    shipments. At the same time, the [D]efendants
    sharpened the surcharges’ sting, with all four dropping
    their trigger prices between March 2003 and March
    2004. . . .
    The heyday of the rate-based fuel surcharge did
    not last. Eventually, the Surface Transportation Board
    (STB) put an end to the practice with respect to
    common carrier traffic within its regulatory authority.
    See Rail Fuel Surcharges, Ex Parte No. 661, 
    2007 WL 201205
     (S.T.B. Jan. 25, 2007). The STB was especially
    troubled by the disconnect between the purported
    rationale for the fuel surcharges—fuel cost recovery—
    and the formula’s dependence on base rates, which
    need not reflect the marginal fuel costs of a particular
    shipment. See 
    id. at *4
    . The [STB] decision did not,
    however, directly implicate those shippers whose
    traffic was governed by bilateral contract. See 
    id. at *10
    .
    
    Id. at 248
    .
    Following the STB’s decision, shippers filed lawsuits
    alleging that the Railroads had violated antitrust laws by
    conspiring to fix fuel surcharges for traffic outside the STB’s
    jurisdiction. See 
    id.
     Two of those actions are now before this
    court. The first, In re: Rail Freight Fuel Surcharge Antitrust
    Litigation, MDL No. 1869, No. 1:07-mc-00489 (D.D.C.),
    includes cases brought against all four Defendants and
    consolidated by the Judicial Panel on Multidistrict Litigation.
    The matter has been before this court several times before. See
    Fayus Enters. v. BNSF Ry. Co., 
    602 F.3d 444
    , 447-54 (D.C.
    Cir. 2010) (affirming dismissal of state law claims); In re Rail
    9
    Freight Fuel Surcharge Antitrust Litig., 725 F.3d at 254-55
    (vacating class certification); In re: Rail Freight Fuel
    Surcharge Antitrust Litig. - MDL No. 1869, 
    934 F.3d 619
    , 622-
    27 (D.C. Cir. 2019) (affirming denial of class certification).
    The second action, Oxbow Carbon & Minerals LLC v. Union
    Pacific Railroad Co., No. 1:11-cv-01049 (D.D.C.), involves
    claims against Union Pacific and BNSF only.
    In advance of the District Court’s consideration of
    summary judgment motions in both cases, Defendants invoked
    Section 10706 to exclude certain documents upon which
    Plaintiffs seek to rely. Defendants argue that the contested
    documents are inadmissible under Section 10706 because they
    constitute evidence of discussions or agreements concerning
    interline movements. Noting that it would “be the first court to
    interpret Section 10706 since Congress enacted the statute in
    1980,” the District Court invited the Government to submit a
    statement of interest reflecting the views of the Department of
    Justice, the Federal Trade Commission, and the STB on the
    interpretation and application of the statute. See Order (Mar.
    16, 2020), No. 1:07-mc-00489, ECF No. 947, reprinted in Joint
    Appendix (“J.A.”) 420-22. The court also permitted the
    plaintiffs in a related multidistrict litigation pending before a
    different District Court judge to file memoranda addressing the
    motions. See generally In re Rail Freight Fuel Surcharge
    Antitrust Litig. (No. II) - MDL No. 2925, No. 1:20-mc-00008
    (D.D.C.).
    In the decision now under review, the District Court
    denied Defendants’ motions to exclude evidence under Section
    10706. In re Rail Freight Fuel Surcharge Antitrust Litig., 
    520 F. Supp. 3d 1
    , 15-38 (D.D.C. 2021). The court held that a
    discussion or agreement “concern[s] an interline movement of
    the rail carrier” within the meaning of Section 10706 only if the
    discussion or agreement is about “an identifiable movement or
    10
    movements with identifiable circumstances, such as a specific
    shipper, specific shipments, and specific destinations” and “all
    of the parties to the discussion or agreement participate in the
    interline movement or movements that are the subject of the
    discussion or agreement.” 
    Id. at 29-30
    . The court also held that
    a discussion or agreement about “potential interline business of
    the participating carriers without regard to specific shipments
    or movements” does not qualify for exclusion under the statute.
    
    Id. at 29
    . Turning to the issue of documents that are internal to
    one rail carrier, the court held that a railroad’s internal
    documents “may be evidence of a protected discussion or
    agreement to the extent that [the internal document]
    summarizes or otherwise conveys the substance of a discussion
    or agreement that occurred between two or more rail carriers.”
    
    Id. at 27
    . Finally, the District Court concluded that documents
    qualifying for exclusion under the statute “need not be either
    admitted or excluded in their entirety.” 
    Id.
     Instead, the court
    held, the statute’s protections may be implemented through
    redactions and, “to the extent that redaction is impracticable or
    inadvisable, limiting instructions may be employed.” 
    Id. at 26
    .
    Defendants then moved to have the District Court certify
    its order for interlocutory appeal. The District Court granted
    the motions and certified its order for immediate review. In re
    Rail Freight Fuel Surcharge Antitrust Litig., 
    2021 WL 2433737
    , at *6-13 (D.D.C. June 15, 2021). Defendants
    petitioned this court for permission under 
    28 U.S.C. § 1292
    (b)
    to appeal, and a motions panel of this court granted the petitions
    without prejudice to reconsideration by the merits panel. See
    Order (Aug. 19, 2021), reprinted in J.A. 85-86.
    We exercise our discretion to hear these consolidated
    interlocutory appeals pursuant to 
    28 U.S.C. § 1292
    (b).
    “[A]ppellate jurisdiction applies to the order certified to the
    court of appeals, and is not tied to the particular question

    formulated by the [D]istrict [C]ourt.” Yamaha Motor Corp.,
    U.S.A. v. Calhoun, 
    516 U.S. 199
    , 205 (1996). As such, we
    “may address any issue fairly included within the certified
    order.” 
    Id.
    II. ANALYSIS
    On appeal, Defendants principally challenge: (1) the
    District Court’s interpretation of Section 10706’s phrase
    “concerned an interline movement”; (2) the court’s holding that
    a rail carrier’s internal documents are not inadmissible under
    Section 10706 unless they convey the substance – rather than
    merely the existence – of a discussion or agreement concerning
    interline movements; (3) the court’s conclusion that the
    statute’s protections can be implemented via redactions; and
    (4) the court’s conclusion that judges can employ limiting
    instructions under certain circumstances to enforce the
    protections afforded by Section 10706. We address these issues
    in order below.
    A. Standard of Review
    “The court reviews de novo the [D]istrict [C]ourt’s . . .
    statutory interpretation.” United States ex rel. Am. Civ. Constr.,
    LLC v. Hirani Eng’g & Land Surveying, PC, 
    26 F.4th 952
    , 956
    (D.C. Cir. 2020), reissued 2022.
    B. “Concerned an Interline Movement”
    We turn first to the meaning of the statutory phrase
    “concerned an interline movement.” In interpreting a statute,
    this court begins “with the language of the statute itself” and,
    if necessary, “may turn to other customary statutory
    interpretation tools, including structure, purpose, and
    legislative history.” Genus Med. Techs. LLC v. FDA, 
    994 F.3d 12
    631, 637 (D.C. Cir. 2021) (internal quotation marks and
    citations omitted).
    Before this court, Defendants argue that a discussion or
    agreement “concern[s] an interline movement” within the
    meaning of Section 10706 if the discussion or agreement “is
    about—that is, it has practical bearing on—the discussant
    railroads’ shared interline traffic.” Opening Br. of Appellants
    33. On their read, this “is true regardless of how specific or
    general the discussion is, and regardless of whether the
    discussion might be said to concern other things too.” 
    Id.
     at 33-
    34. Defendants maintain that “many of the issues that matter
    for interline traffic also matter for single-line traffic,” and that
    “[n]obody has explained how interlining railroads could have
    a reasonable conversation about many essential topics—fuel
    costs among them—that would not also seem relevant (at least
    in hindsight) to all traffic.” 
    Id. at 59-60
    . For their part, Plaintiffs
    contend that a discussion or agreement “concern[s] an interline
    movement” only if the discussion or agreement is “limited to
    interline movements and [does not] include single-line
    movements.” Redacted Br. for Pls.-Appellees 22. In Plaintiffs’
    view, Defendants’ contrary interpretation “would transform a
    narrow evidentiary rule into a license for collusion on all rates.”
    
    Id. at 25
    . Neither party has it right.
    We hold that a discussion or agreement “concern[s] an
    interline movement” only if Defendants meet their burden of
    showing that the movements at issue are the participating rail
    carriers’ shared interline traffic. A discussion or agreement
    need not identify a specific shipper, shipments, or destinations
    to qualify for exclusion; more general discussions or
    agreements may suffice. For example, evidence of a discussion
    or agreement about policies applicable to all of the
    participating railroads’ shared interline traffic is excludable
    under Section 10706, provided the evidence satisfies the
    13
    statute’s other requirements and the court can identify the
    movements at issue as the carriers’ shared interline traffic. The
    same is true of discussions or agreements about the formation
    of the participating railroads’ interline agreements, as well as
    about their anticipated shared traffic. A single document may
    reference more than one discussion or agreement. See In re Rail
    Freight Fuel Surcharge Antitrust Litig., 
    520 F. Supp. 3d 1
    , 25
    (D.D.C. 2021). Defendants acknowledge that this is so. See
    Opening Br. of Appellants 74-75. The court must consider each
    discussion and agreement separately in determining whether it
    should be excluded under Section 10706.
    Consistent with the foregoing interpretation of the statute,
    evidence of discussions or agreements about single-line traffic
    or about freight traffic generally is not excludable under
    Section 10706. A de minimis (i.e., brief and insignificant)
    reference to non-interline traffic does not automatically
    disqualify evidence from exclusion under Section 10706.
    Instead, evidence of discussions or agreements about
    identifiable interline movements that also contain a de minimis
    reference to other traffic can qualify for exclusion under
    Section 10706 if the carriers demonstrate that the reference was
    either fleeting and inconsequential or appropriate to the
    advancement of the interline discussion itself. To carry this
    burden, the railroads must demonstrate that any such reference
    did not change the focus of the discussion or agreement away
    from the participating railroads’ shared, identifiable interline
    movements.
    Our construction of Section 10706 reflects the most
    natural reading of the statute’s text. Rail freight traffic involves
    two discrete types of movements: interline and single-line, see
    Br. for the United States and the FTC as Amici Curiae in
    Support of Pls.-Appellees and Affirmance 1, 11, and all parties
    before this court agree that the term “concerned” as it appears
    14
    in the statute is synonymous with “about,” see Opening Br. of
    Appellants 53 n.4; Redacted Br. for Pls.-Appellees 26; Reply
    Br. of Appellants 22. Congress used “concerned” to connect
    “discussion or agreement” with “an interline movement,”
    indicating that a discussion or agreement does not “concern[]
    an interline movement” if the discussion or agreement is about
    single-line traffic or rail freight generally. Reading “concerned
    an interline movement” to encompass discussions or
    agreements about a mutually inconsistent category – i.e.,
    single-line movements – defies logic.
    Our interpretation is also consistent with the Act’s
    purpose. The Act states that, “[i]n regulating the railroad
    industry,” the Government’s policy is “to allow, to the
    maximum extent possible, competition and the demand for
    services to establish reasonable rates for transportation by rail.”
    
    49 U.S.C. § 10101
    (1); see also ICC v. Texas, 
    479 U.S. 450
    , 460
    (1987) (“In its statement of rail transportation policy, Congress
    unambiguously expressed its interest in allowing free
    competition, to the maximum extent possible, to govern the
    financial health of the railroad industry.”). Adopting an
    expansive interpretation of “concern[s] an interline movement”
    would render Section 10706 “little more than a de facto
    immunity for anticompetitive actions that happen to coincide
    with interline traffic.” Br. for the United States and the FTC as
    Amici Curiae in Support of Pls.-Appellees and Affirmance 13
    (internal quotation marks omitted). We decline to adopt an
    interpretation of the statute so clearly at odds with Congress’
    intent.
    At the same time, Section 10706, by its plain terms,
    evinces Congress’ clear desire to allow rail carriers to
    collaborate with one another about their shared interline traffic.
    In addition to promulgating the rule of evidence at issue here,
    the statute provides that proof of a conspiracy “may not be
    15
    inferred from evidence that two or more rail carriers acted
    together with respect to an interline rate or related matter and
    that a party to such action took similar action with respect to a
    rate or related matter on another route or traffic.”
    § 10706(a)(3)(B)(ii); see also H.R. Rep. No. 96-1430, at 114
    (1980) (“[C]arriers must talk to competitors about interline
    movements in which they interchange. That requirement could
    falsely lead to conclusions about rate agreements that were
    lawfully discussed.”). Interpreting Section 10706 to require
    discussions or agreements to contain shipment-by-shipment
    specificity, or to strip rail carriers of the statute’s protections
    based solely on a de minimis reference to non-interline traffic,
    would significantly frustrate the statute’s objective. Finally, the
    statute’s use of the singular phrase “an interline movement”
    should be interpreted to include multiple movements. See 
    1 U.S.C. § 1
     (“In determining the meaning of any Act of
    Congress, unless the context indicates otherwise—words
    importing the singular include and apply to several persons,
    parties, or things.”). That reinforces our conclusion that more
    general discussions or agreements about all interline traffic are
    excludable under Section 10706.
    Defendants’ principal counterargument to the reading of
    “concerned an interline movement” we adopt is that our
    interpretation renders superfluous the second clause of Section
    10706. Under that clause, evidence of a discussion or
    agreement “concern[ing] an interline movement” is
    inadmissible only if “the discussion or agreement would not,
    considered by itself, violate the [antitrust] laws.”
    § 10706(a)(3)(B)(ii)(II). On Defendants’ read, discussions and
    agreements about participating carriers’ shared, identifiable
    interline movements “are never unlawful (at least outside the
    most contrived hypotheticals).” Opening Br. of Appellants 61.
    Therefore, they contend, the “paradoxical result,” id., of our
    construction is that no discussion “concern[ing] an interline
    16
    movement” could ever, “considered by itself, violate the
    [antitrust] laws,” § 10706(a)(3)(B)(ii)(II).
    We are not persuaded. As the Government’s amicus brief
    explains, a discussion or agreement can both “concern[] an
    interline movement” consistent with our interpretation and
    violate antitrust laws. See Br. for the United States and the FTC
    as Amici Curiae in Support of Pls.-Appellees and Affirmance
    18-19. For example, a larger carrier might pressure a smaller
    carrier into accepting an unreasonably low share of interline
    profits under threat of losing access to interline business. See,
    e.g., Del. & Hudson Ry. Co. v. Consol. Rail Corp., 
    902 F.2d 174
    , 177-81 (2d Cir. 1990) (holding that a smaller rail carrier
    presented genuine issues of material fact with respect to its
    antitrust claims against a larger carrier where the larger carrier
    “placed [the smaller carrier] in a bind between giving up almost
    all of its profits on a given route and losing entirely the ability
    to carry freight on the route”). Accordingly, the “considered by
    itself” clause retains full force under our reading of the statute.
    C. Internal Documents
    Next, Defendants challenge the District Court’s ruling that
    a rail carrier’s internal documents are not inadmissible under
    Section 10706 unless they “summarize[] or otherwise convey[]
    the substance of a discussion or agreement that occurred
    between two or more rail carriers.” In re Rail Freight Fuel
    Surcharge Antitrust Litig., 520 F. Supp. 3d at 27. Defendants
    argue that an internal document referring to the existence of a
    discussion or agreement concerning interline movements with
    another carrier, even without summarizing the substance of
    that discussion or agreement, is inadmissible. They maintain
    that “[a]n internal document that references an interline
    discussion, but does not convey its substance, is an especially
    powerful invitation to jury speculation about the contents of
    17
    that discussion,” potentially forcing railroads “to admit the
    entire interline discussion, just to show that there is nothing
    nefarious about it.” Opening Br. of Appellants 67-68. Plaintiffs
    disagree, contending that internal documents must reference
    the substance of an interlining discussion or agreement with
    another carrier to qualify for exclusion under Section 10706. In
    their view, a carrier’s internal document that does not reference
    the substance of a such a discussion or agreement “cannot
    satisfy the plain language of the evidentiary exclusion.”
    Redacted Br. for Pls.-Appellees 41.
    We agree with Defendants that a rail carrier’s internal
    documents need not convey the substance of a discussion or
    agreement concerning interline movements to qualify for
    exclusion under the statute. Instead, an internal document that
    references only the existence of such a discussion or agreement
    with another carrier is inadmissible, provided the document
    meets the statute’s other requirements and the court can
    identify the subject of the underlying discussion or agreement
    as the participating railroads’ shared interline traffic. This
    holding applies with equal force to internal documents
    prepared in advance of discussions or agreements with other
    carriers concerning shared interline movements.
    The plain language of the statute supports this conclusion.
    Section 10706 provides that evidence of a discussion or
    agreement between or among rail carriers is inadmissible if,
    among other requirements, “the discussion or agreement”
    “concerned an interline movement of the rail carrier.”
    § 10706(a)(3)(B)(ii)(II) (emphases added). Such a discussion
    or agreement is “of the rail carrier” only if the discussion or
    agreement is between or among carriers participating in or that
    are actively considering participation in the interline traffic at
    issue. The plain terms of the statute require the “discussion or
    agreement” itself – but not necessarily the evidence of that
    18
    discussion or agreement – to be between or among
    participating carriers. This indicates that a carrier’s internal
    document can qualify for exclusion, provided the underlying
    discussion or agreement to which the document refers is about
    the participating carriers’ shared interline movements. As such,
    an internal document that refers to the existence of a discussion
    or agreement concerning interline movements – without
    conveying its substance – can qualify for exclusion under
    Section 10706, provided the court is satisfied that the
    discussion or agreement to which the internal document refers
    concerns the participating railroads’ shared interline traffic.
    This interpretation is also consistent with Congress’
    expressed desire to allow railroads to collaborate with one
    another about their shared interline traffic. See Section II.B,
    supra. Reaching a contrary conclusion could cause a jury to see
    references to an interlining discussion’s existence even if
    separate evidence of that discussion’s substance is
    inadmissible, inviting speculation about what the carriers
    discussed. Such an outcome would contravene Congress’ clear
    purpose for enacting Section 10706.
    For these reasons, a carrier’s internal documents need not
    convey the substance of a discussion or agreement concerning
    interline movements to qualify for exclusion under the statute.
    D. Redactions
    Defendants challenge the District Court’s holding that
    Section 10706 can be implemented via redactions. On
    Defendants’ read, the statute’s directive that qualifying
    evidence “shall not be admissible” indicates that courts cannot
    implement the statute’s protections via redactions. Instead,
    they argue that under Section 10706, evidence either “comes
    in, or it stays out.” Opening Br. of Appellants 70. Plaintiffs
    19
    disagree, maintaining that the District Court properly
    authorized redactions. They argue that the Railroads’ argument
    against redactions reflects an attempt “to shield unlawful price-
    fixing agreements if there is a single reference somewhere in
    the same communication to shared interline movements.”
    Redacted Br. for Pls.-Appellees 55.
    We agree with Plaintiffs that Section 10706 can be
    implemented through redactions of truly segregable portions of
    documents. As Defendants concede, “different parts of a single
    document could conceivably reflect two separate discussions,
    one of which concerns interline traffic, and one of which does
    not.” Opening Br. of Appellants 74-75. Under such a scenario,
    “redacting only the interline discussion would be appropriate
    because the unredacted material is not evidence of a qualifying
    discussion, and thus lacks any claim to inadmissibility under
    the statute.” Id. at 75.
    The text of Section 10706 does not address the issue of
    redactions. Absent a clear congressional directive to the
    contrary, we decline to read the statute as divesting trial courts
    of their authority to redact truly segregable portions of
    documents. See United States v. Lemonakis, 
    485 F.2d 941
    , 949
    (D.C. Cir. 1973) (recognizing trial courts’ “discretionary power
    to delete objectionable portions” of evidence “where
    appropriate”). As such, where segregable portions of
    documents contain protected evidence of discussions or
    agreements concerning interline movements, the District Court
    may employ redactions. However, the Railroads remain free to
    argue that any contested documents that might be subject to
    redaction should be excluded in their entirety where the
    probative value of the evidence is substantially outweighed by
    the danger of unfair prejudice. See Fed. R. Evid. 403.
    20
    E. Limiting Instructions
    Finally, the Railroads argue that limiting instructions are
    irreconcilable with the text and purpose of Section 10706. We
    largely agree.
    Defendants convincingly contend that,
    [i]n practical effect, the limiting instruction approach
    negates the statute’s purpose. It allows a jury to see the
    interline evidence Congress sought to exclude, and
    leaves it up to the jury to decide what evidence to
    disregard. But leaving it up to the jury is exactly what
    Congress did not want, just as it did not want a jury
    deciding whether, having seen evidence of lawful
    interline collaboration, a conspiracy existed between
    interline partners. Exclusion is the only remedy that
    serves Congress’s purpose.
    Opening Br. of Appellants 74. Defendants raise compelling
    points in support of their claim that the text, structure, and
    purpose of Section 10706 rule out limiting instructions:
    Unlike many rules of evidence that permit [limiting
    instructions], Section 10706 explicitly prescribes a
    different remedy: The court must evaluate the evidence
    “before allowing [its] introduction,” and evidence
    meeting the statutory criteria “shall not be admissible.”
    
    49 U.S.C. § 10706
    (a)(3)(B)(ii). That exclusion-based
    approach to evidence stands in meaningful contrast to
    the instruction-based approach that Section 10706 takes
    to impermissible inferences. And in practical effect, the
    District Court’s approach negates the statute’s purpose
    by allowing a jury to see the interline evidence
    Congress sought to exclude.
    21
    
    Id. at 31-32
     (second alteration in original).
    What is clear here is that Section 10706 “includes both an
    inferential protection and an evidentiary rule, which operate
    very differently at a jury trial.” 
    Id. at 71
    . “The inferential
    portion directs the jury not to infer a conspiracy from certain
    parallel action, and it is implemented through an instruction at
    trial.” 
    Id. at 72
    . However, the Section 10706 evidentiary rule
    is meant to guard against juries “fail[ing] to distinguish (a)
    lawful interline discussions plus parallel action from (b)
    conspiracy.” 
    Id.
     Congress therefore made it clear that “‘[t]he
    court shall determine’ whether the requirements of Section
    10706 are met ‘before allowing the introduction of any such
    evidence.’” 
    Id. at 72-73
     (quoting § 10706(a)(3)(B)(ii)).
    Limiting instructions will not do.
    In the light of the text and purpose of Section 10706, we
    hold that limiting instructions may not be used to enforce the
    protections of the statute except in those very rare instances in
    which protected evidence is unavoidably and inextricably
    intertwined with evidence that does not qualify for exclusion.
    And in these limited situations, the court must take care to craft
    instructions that do not open the door to a jury’s drawing the
    very type of inferences that Congress intended Section 10706
    to protect against.
    III. CONCLUSION
    For the foregoing reasons, we affirm in part and reverse in
    part the District Court’s interpretation of Section 10706. We
    vacate the District Court’s order and remand for the court to
    reconsider the evidence at issue consistent with this court’s
    interpretation of the statute.
