Majority — Frankfurter J.
delivered the opinion of the Court.
This case is here to review a judgment of the Supreme Court of Tennessee sustaining an assessment of petitioner’s property, tangible and intangible, under that state’s ad valorem tax law. All Tennessee property is subject to such a tax; but there are two schemes of procedure for making assessments, one for public service corporations and one for other taxpayers. As to ordinary property the task of valuation rests upon officials of the various counties. For public service corporations the assessments
In anticipation of a certification by the Board of its final assessment preliminary to the collection of taxes based upon it, the Railway brought an appropriate proceeding in the state courts to set aside what it claimed was the void “excess of the fair taxable value” of its property. This suit was dismissed by the trial court and its judgment was affirmed by the Supreme Court of Tennessee with two justices separately dissenting. 140 S. W. 2d 781 . Because of petitioner’s claim that the result below was inconsistent with decisions of this Court, we granted certiorari. 309 U. S. 651 . The assessment was contested below on objections grounded in both state and federal constitutions. Here, of course, only federal questions are open. Petitioner claims that the challenged
We shall first consider the claim basted on the historic implications of the Commerce Clause as a limitation upon the state’s taxing power. Petitioner argued that Tennessee has taxed values which are in truth outside its borders, thereby burdening that which the Commerce Clause has left free. The guiding principles for adjustment of the state’s right to secure its revenues and the nation’s duty to protect interstate transportation are by this time well settled. The problem to be solved is what portion of an interstate organism may appropriately be attributed to each of the various states in which it functions. Basic to the accommodation of these conflicting state and national interests is realization that by its very nature the problem is incapable of precise and arithmetical solution. In tapping these common sources of revenue a state cannot, we have held, use a fiscal formula, whatever may be its appearance of certitude, to project the taxing power of the state plainly beyond its borders. Wallace v. Hines, 253 U. S. 66 . In the light of these principles, Tennessee has not overstepped its bounds.
In basing its apportionment on mileage, thte Tennessee Commission adopted a familiar and frequently sanctioned formula. Pullman’s Car Co. v. Pennsylvania, 141 U. S. 18 ; Maine v. Grand Trunk Ry. Co., 142 U. S. 217 ; Pittsburgh, C., C. & St. L. Ry. Co. v. Backus, 154 U. S. 421 ; Branson v. Bush, 251 U. S. 182 . See 2 Cooley on Taxation, pp. 1660-64. Its asserted inapplicability to the particular situation is rested on petitioner’s evidence as to the comparative revenue-producing capacity of its lines in and out of Tennessee. But both the Commission and the Supreme Court of the state thought that this evidence, however weighty, was insufficient to displace the relevance of the formula. In a matter where exactness is con-
This brings us to the Company’s claims under the Fourteenth Amendment. The Railway first asserts that it is a victim of such invidious discrimination in the administration of Tennessee’s tax statutes as is proscribed by the guaranty of “the equal protection of the laws.” The claim is founded upon the following circumstances. As we have already indicated, there are two separate modes for the assessment of property in Tern nessee, each with its distinctive procedure. The property of public service corporations is assessed by the Commission; all other property by local officials. This broad classification, separating two very different types of property, has been reflected, according to petitioner’s contention, by a corresponding difference in the bases of assessment. For more than forty years, so it was urged before the courts of Tennessee and later here, the county assessors have systematically valued property at far less than its true worth, while utility and railroad properties have been assessed by the Commission at full value.[1]

But were we to take judicial notice of that which these minutes were offered to show, and therefore to regard the ground taken by the state court as a strained evasion' of the differentiation between utility property on the one hand and all the rest on the other, we should still find no denial of the equal protection of the laws. It must be emphasized that the Company makes no claim
That the states may classify property for taxation; may set up different modes of assessment, valuation and collection; may tax some kinds of property at higher rates than others; and in making all these differentiations may treat railroads and other utilities with that separateness which their distinctive characteristics and functions in society make appropriate — these are among the commonplaces of taxation and of constitutional law.

Finally, the Railway claims that the valuation of its entire system, on the basis of which the Commission has measured Tennessee’s shares, is so far in excess of “full cash value” as to offend the Due Process Clause. The details on which this claim is based are fully set forth in the opinions below and call only for summary treatment here. The argument basically derives from the fact that the Commission’s valuation of petitioner’s system was the same as that for the previous biennium, although numerous adverse economic factors are alleged to have greatly reduced the property’s worth. But railroads, unlike farms and city lots and stocks and bonds, are not objects of exchange. The very notion of. a “full cash value” for a railroad is in many respects artificial. See 1 Bonbright, The Valuation of Property, pp. 511-632. Whatever may be the pretenses of exactitude in determining such a “value,” to claim for it “scientific” validity, is to employ the teim in its loosest sense. Compare Chicago, B. & Q. Ry. Co. v. Babcock, 204 U. S. 585 , 598. Thorough canvass by the state courts found no justification for upsetting the determination of the Commission, and we could scarcely find warrant in the record for doing so. But even assuming that there was an over-assessment, constitutional invalidity would not follow. If the needs of a state require higher taxes, the Fourteenth Amendment certainly does not bar their imposition. The maintenance of higher assessment in the face of declining value is merely another way of achieving the same result.
Affirmed.
