American freight rail, while largely deregulated, is still overseen by the Surface Transportation Board (STB). This federal agency retains substantial power to regulate freight rail, powers that the STB normally deploys rarely. But these powers are seen by some as an opportunity to enlist the power of the federal government in business disputes, using government to extract rents to pad bottom lines. An example of this can be seen in the proposed “reciprocal switching” regulations from the STB. Unable to prove that prices that railroads are charging are unfair, some of their shipping customers have gone to the federal government to try to force lower prices through regulation, regulation which has been described as backdoor price controls.
