The Board is adopting final rules establishing that a person receiving rail cars from a rail carrier for loading or unloading who detains the cars beyond the "free time" provided in the carrier's governing tariff will generally be responsible for paying demurrage, if that person has actual notice, prior to rail car placement, of the demurrage tariff establishing such liability. The Board also clarifies that it construes the provisions of 49 U.S.C. 10743, titled "Liability for payment of rates," as applying to carriers' line-haul rates, but not to carriers' charges for demurrage.
