Title 49 › Subtitle SUBTITLE IV— INTERSTATE TRANSPORTATION › Part A— RAIL › Chapter 107— RATES › Subchapter I— GENERAL AUTHORITY › § 10707
When someone says a rail carrier’s rate is too high, the Board must decide if the carrier has market dominance over that move. Market dominance means there is no real competition from other railroads or other ways to move the freight. If the Board finds no market dominance, that ends the issue in that rate case unless the Board or a court changes it. If the Board finds market dominance, it can then check if the rate is higher than a reasonable maximum and say the rate is unreasonable, but finding dominance does not by itself mean the rate is too high. If the carrier shows the rate gives a revenue-to-variable-cost ratio under 180 percent, the Board must find the carrier does not have market dominance. Variable costs must be worked out from the carrier’s unadjusted costs using the Uniform Rail Costing System (or a Board-approved alternative), adjusted quarterly for local wages and prices and any Board-specified changes. A shipper may try to rebut the carrier’s cost showing under rules the Board sets. A ratio of 180 percent or more does not by itself prove dominance or that the rate is unreasonable.
