FILE - Smoke emanates from a railroad car after an explosion at Union Pacific's Bailey Yard, Sept. 14, 2023, in North Platte, Neb. The explosion of a shipping container filled with toxic acid inside the worlds largest railyard, combined with hundreds of rules violations inspectors found there, raises questions about Union Pacific's safety and the effectiveness of the rules for shipping hazardous materials. The Sept. 14 blast fortunately happened in a remote corner of the railyard and the resulting fire did not spread widely. (Ryan Herzog/The Telegraph via AP, File)
