Note 495 — Chapter VII · UNION PACIFIC
Reading edition
The Court held that while up to the passage of the Thurman Act expenditures for improvements could be deducted from gross earnings in calculating net, the language of that Act seemed to preclude the deduction of any charges for improvements or betterments, or increase of permanent value of the works in any manner whatever. See 99 U. S. 402; 99 U. S. 455; 138 U. S. 84.
