49 C.F.R. § 1108.2
(a) The Board's intent. The Board favors the resolution of disputes through the use of mediation and arbitration procedures, in lieu of formal Board proceedings, whenever possible. This section provides for the creation of a binding, voluntary arbitration program in which parties, including shippers and railroads, agree in advance to arbitrate certain types of disputes with a limit on potential liability of $25,000,000 in rate disputes, including any rate prescription, and $2,000,000 in other disputes unless the parties mutually agree to a lower award cap. The Board's arbitration program is open to all parties eligible to bring or defend disputes before the Board.
(b) Limitations to the Board's arbitration program. These procedures shall not be available:
(4) To resolve disputes that are solely between two or more rail carriers.
Parties may only use these arbitration procedures to arbitrate matters within the statutory jurisdiction of the Board.
