The Surface Transportation Board (STB) “should reject the efforts of a few parties … to delay and prolong this proceeding by claiming the [recently filed Union Pacific-Norfolk Southern] Application [seeking authorization to combine their networks under common ownership and form a U.S. transcontinental] is incomplete,” the two railroads urged in a Jan. 2 filing.

The Board therefore should accept the Application.” According to UP and NS, the parties claiming that the application is incomplete are “primarily competitors,” who will “experience increased competition as a result of the merger.” They include BNSF, CN, Canadian Pacific Kansas City, and CSX, plus the National Grain and Feed Association (NGFA), representing one of the railroads’ largest customer bases.
