WASHINGTON, D.C. –– An Oct. 30 letter to the Surface Transportation Board co-authored by Senators John Hoeven (R-N.D.) and Amy Klobuchar (D-Minn.) asks the STB to “closely scrutinize” the proposed Union Pacific-Norfolk Southern merger, stressing “the potential disruptions to U.S. rail service resulting from a merger of this scale” and “the need for the STB to fully analyze the potential impact on long-term competition, including for agriculture producers, many of whom already face limited options for accessing rail service.”
