PPL Mоntana, LLC (PPL) filed a complaint with the Surface Transportation Board, alleging the rail rates charged by intervenor BNSF Railway Company (BNSF) were unreasonably high. The Board disagreed and dismissed the complaint. PPL now petitions for review. Finding no basis for upsetting the Board’s decision, we deny the petition.

When a shipper files a rate complaint, see 49 U.S.C. §§ 10704(b), 11701, the Board is charged with determining whether the cаrrier targeted by the complaint has “market dominance,” id. § 10707(b)— that is, whether there is “an absence of *1242 effective competition from other rail carriers or modes of transportation for the transportation to which a rate applies,” id. § 10707(a). 1 If so, the carrier’s rate for the captive traffic must be “reasonable.” Id. § 10701(d)(1). If the Board determines the rate is unreasonablе, see id. § 10707(c), it may prescribe the maximum rate that can be charged, id. § 10704(a)(1).
The Board determines reasonableness according to the “constrained market pricing” (CMP) principles enunciated in
COAL RATE GUIDELINES, NATIONWIDE,
A SAC analysis seeks to determine the lowest cost at which a hypothetical efficient carrier cоuld provide service to the complaining shipper or a group of shippers that benefits from sharing joint and common costs.

railroads functioning in a noncompetitive market will be required to price as if alternatives to their services were available. That is, their rates will be judged against simulated competitive prices. As a result, the efficiencies of a contestable market will serve as the guide for establishing maximum rates on captive coal traffic.
Id.
at 542,
To proceed under the SAC constraint, a complaining shipper designs and presents to the Board a hypothetical stand-аlone railroad (SARR) to serve the traffic group; the traffic group may contain both the complaining shipper’s traffic — the issue traffic — as well as other traffic selected to take advantage of the “benefits of any inherent production economies.”

PPL ships coal by rail via BNSF from mines in Wyoming’s Powder River Basin to PPL’s Corette generating facility at Billings, Montana. In July 2000, PPL filed a complaint with the Board, challenging the reasonableness of the rail rates charged by BNSF.
PPL invoked the SAC constraint and, accordingly, proffered a SARR that can be viewed as consisting of two segments: a high-density “north-south” segment and a low-density “western” segment. The north-south segment, extending south from Buckskin, Wyoming — through Campbell — to Converse, Wyoming, was used to originate coal in the Powder River Basin. Thе longer western segment, branching off the north-south segment at Campbell, extended westward out of the Powder River Basin for more than 200 miles to PPL’s plant in Billings and to other Montana locations. All of the traffic PPL included in the SARR, with the exception of PPL’s own traffic, is “cross-over” traffic, which originates or terminates on the residual real-world railroad and is intеrchanged with the SARR. Most of the cross-over traffic moved no more than 26 miles on the north-south segment.
BNSF challenged PPL’s SAC presentation, arguing, in relevant part, that “PPL has impermissibly cross-subsidized the issue traffic (and other traffic [traveling on the western segment]) as a result of the exorbitant revenues that are assumed to be earned by a subset of its cross-over traffic.” Joint Appendix (“J.A.”) 14. To demonstrate this cross-subsidy, BNSF calculated revenues from cross-over traffic that used only the north-south segment to be far in excess of the stand-alone cost of the north-south segment.
PPL recognized that BNSF was advocating a rule, in part, “designed to exclude the possibility that non-issue traffic on the SARR is subsidizing issue traffic.” Id. at 61. Discounting such concerns, PPL suggested the SAC test only prevented the complaining shipper from being forced to subsidize other traffic, and that the complaining shipper was free to design a SARR in which other traffic subsidized the complaining shipper. Nonetheless, in the event the Board was troubled by such cross-subsidies, PPL offered an alternative to exаmining the revenues and SAC of the north-south segment:
Assuming [cross-subsidization of the issue traffic by non-issue traffic] is a legit *1244 imate concern ..., there is a more direct test for cross subsidy that would not impose prohibitive litigation burdens and expenses on complainants. Traffic that is covering its attributable cost is not being subsidized. This test has been met both for the issue traffic аnd for the cross-over traffic ....
Id. (emphasis added).
The Board
did
consider cross-subsidization of the issue traffic to be a legitimate concern, observing that “PPL’s contention that non-issue traffic may be used to cross-subsidize the complaining shipper’s rate is inconsistent with CMP principles.”
PPL MONTANA LLC V. BURLINGTON N. & SANTA FE RY. CO.,
STB Docket No. 42054, Dec. No. 31155,
Thus, the Board conducted a threshold cross-subsidy inquiry to determine “whether the western leg of the [SARR] would earn sufficient revenues to cover its attributable cоsts or whether it would require a cross-subsidy in order to be viable over the 20-year analysis period.” Id. The Board accepted “the majority of the evidence submitted by PPL regarding the operations and construction of the western segment,” id., and credited to the western segment the revenues of all traffic that used any portion of the western segment, id. at *6. Nonetheless, the Boаrd concluded the western segment would still “not be self-sustaining,” id. at *5, as its attributable costs outstripped its revenues by $9.26 million, id. at *7. Accordingly, because PPL had “failed to show that the rates charged by BNSF for transporting coal traffic to the Corette power plant are unreasonably high,” id., the Board dismissed PPL’s complaint.
PPL moved for reconsideration, contending,
inter alia,
that it should be allowed to revise its evidentiary presentation to comport with the Board’s threshold cross-subsidy test. However, the Board ultimately declined to revive PPL’s complaint.

We will set aside a Board decision only if it is “arbitrary, capricious, an abuse of discretion, ... otherwise [unlawful, or] ... unsupported by substantial evidence.” 5 U.S.C. § 706(2)(A), (E);
see Burlington N. R.R. v. Surface Transp. Bd.,
PPL contends the Board’s reliance on its threshold cross-subsidy test tо reject PPL’s complaint is inconsistent with GUIDELINES; that it represents a departure from Board precedent without proper explanation or notice; and that the Board should have reopened the proceeding to allow PPL to adjust its SARR presentation. We are not persuaded.
The Board’s application of its cross-subsidy test is neither arbitrary nor capricious but rather a reasonable interpretation of the principles articulated in
GUIDELINES. See High Plains Wireless, L.P. v. FCC,
PPL’s argument that its SARR would charge lower rates to all of its customers than they currently pay the incumbent railroad missеs the mark; See Petitioner’s Br. at 21 (“So long as the SARR as a whole covers its attributable and unattributable costs while charging lower rail rates than its shipper customers would otherwise pay, there is no cross-subsidy.”). While BNSF may' be charging excessive rates to non-issue traffic on a different section of the line, that does not mean the Board must permit any (or every) captive shipper (such as PPL) to оbtain on its own section of the line a rate reduction even though the current rate is already insufficient to cover its attributable costs. If other shippers are being overcharged, they may bring their own challenges. It is of no moment that a full-fledged SAC analysis might normally proceed by comparing the costs and revenues of the SARR as a whole; the Board’s cross-subsidy test acts as a threshold inquiry, reasonably allowing the Board to halt the SAC analysis in its tracks. 4
Further, we perceive no inconsistency with
post-GUIDELINES
Board precedent. While an agency changing course must supply a reasoned explanation,
see, e.g., Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins. Co.,
In turn, PPL’s argument that the Board failed to give adequate notice of its cross-subsidy test is unavailing. Regardless of whatever notice is due before an agency “reverse[s] a policy that had been the subject of reasonable reliance,”
Williams Natural Gas Co. v. FERC,
Finally, the Board did not abuse its discretion in rejecting PPL’s request to reopen the proceeding so PPL could alter the traffic pattern on its SARR in light of the Board’s cross-subsidy test.

PPL’s contention that the Board "does not have jurisdiction over, or any statutory obligation to protect from abuse, whether in the form of cross-subsidization or in any other form, the traffic and rates of non-complaining shippers,” Petitioner's Br. at 22, is unavailing, as the Board here has remained focused on the issue traffic in determining that the western segment's inability to cover its own attributable costs allows the Board to end the analysis.
