Title 49 › Subtitle SUBTITLE IV— - INTERSTATE TRANSPORTATION › Part PART A— - RAIL › Chapter CHAPTER 107— - RATES › Subchapter SUBCHAPTER I— - GENERAL AUTHORITY › § 10707
Requires the federal board that reviews railroad rates to decide if a railroad lacks real competition when someone says a rate is too high. Market dominance — when other railroads or other transport options do not provide effective competition for that move — is the key idea. The board must make this decision when a rate is challenged or on its own. If the board finds no market dominance, that decision controls the case unless the board or a court changes it. If the board finds market dominance, it can then decide a rate is unreasonable if it goes above a fair maximum, but dominance alone does not prove the rate is too high. A railroad proves it lacks dominance if it shows the revenue-to-variable-cost ratio for the move is under 180 percent. Variable costs must be shown using the Uniform Rail Costing System (or a board alternative), indexed quarterly with board adjustments. A shipper may try to rebut the railroad’s cost showing. A ratio at or above 180 percent creates no automatic assumptions about dominance or reasonableness.
