Title 49 › SUBTITLE IV — INTERSTATE TRANSPORTATION › PART A — RAIL › CHAPTER 107 — RATES › SUBCHAPTER I — GENERAL AUTHORITY › § 10707
When a railroad rate is challenged as too high, the Surface Transportation Board must decide if the railroad has "market dominance," meaning there is no real competition from other railroads or other ways to ship. The Board can make that decision on its own or after a complaint. If the Board finds the railroad does not have market dominance, that decision controls the rate case unless the Board or a court changes it. If the Board finds market dominance, it can then check whether the rate is above a reasonable maximum, but dominance alone does not mean the rate is too high. If the railroad proves the rate brings in less than 180 percent of its variable costs, the Board must find no market dominance. Variable costs are calculated only from the carrier’s unadjusted costs using the Uniform Rail Costing System (or a Board-approved alternative), adjusted quarterly for local wage and price levels and other Board-specified changes. A shipper may try to dispute that cost showing. A rate at or above 180 percent does not create any presumption about dominance or reasonableness.
