Union Pacific managers interfered with US railroad safety assessments, prompting a suspension by the Federal Railroad Administration.

Union Pacific managers hindered US regulatory assessments of railroad safety, coaching employees on responses and suggesting disciplinary action, according to federal regulators. The widespread meddling across Union Pacific's 23-state network forced the Federal Railroad Administration to suspend its safety assessment of the company. Union Pacific claims the issue was limited to one department and stated that it did not intend to influence or impede the assessment.
