“ Thus, trail conversion is permitted only after the Commission determines that rail service will not be not needed in the foreseeable future. This, according to petitioners, reveals that the rail banking rationale is a sham. If Congress really wished to address the problem of shrinking trackage, it would not have left conversions to voluntary agreements between railroads and state and local agencies or private groups. ”

“ Congress in [the statute] did not address the liability of the Government to pay just compensation should a taking occur. Congress' failure specifically to mention or provide for recourse against the Government may reflect a congressional belief that use of data by [the Government] in the ways authorized by [the statute] effects no Fifth Amendment taking or it may reflect Congress' assumption that the general grant of jurisdiction under the Tucker Act would provide the necessary remedy for any taking that may occur. ”

“ It reasoned that the ICC has "plenary and exclusive authority" over abandonments, id., at 151, and that federal law must be considered in determining the property right held by petitioners. "For as long as it determines that the land will serve a 'railroad purpose,' the ICC retains jurisdiction over railroad rights-of-way; it does not matter whether that purpose is immediate or in the future." Ibid. Because the court believed that no reversionary interest could vest until the ICC determined that abandonment was appropriate, the court concluded that the Trails Act did not result in a taking. ”

“ The alternative chosen by Congress is less costly than a program of direct federal trail acquisition because, under any view of takings law, only some rail-to-trail conversions will amount to takings. Some rights-of-way are held in fee simple. See National Wildlife Federation v. ICC, 271 U.S.App.D.C. 1, 10, 850 F.2d 694, 703 (1988) . Others are held as easements that do not even as a matter of state law revert upon interim use as nature trails. ”

“ Rather, petitioners suggest, Congress would have created a mandatory program administered directly by the ICC.
We note at the outset that even under petitioners' reading, the Amendments would still be a valid exercise of congressional power under the Commerce Clause because they are reasonably adapted to the goal of encouraging the development of additional recreational trails. There is no requirement that a law serve more than one legitimate purpose. ”

“ That section speaks in capacious terms of "interim use of any established railroad rights-of-way" (emphasis added) and does not support petitioners' proposed distinction between conversions that might result in a taking and those that do not. Although Congress did not explicitly promise to pay for any takings, we have always assumed that the Tucker Act is an "implie [d] promis [e] " to pay just compensation which individual laws need not reiterate. ”

“ In addition, under § 8 (d) the Federal Government neither incurs the costs of constructing and maintaining the trails nor assumes legal liability for the transfer or use of the right-of-way. In contrast, the costs of acquiring and administering national scenic and national historic trails are borne directly by the Federal Government. ”
