History

Historical Context

The 2001 merger of Union Pacific and Southern Pacific created a dominant railroad entity controlling over 40% of the western U.S. freight market, raising significant antitrust concerns. As the number of major U.S. railroads declined from 40 in the 1980s to just six, the recent rejection of Union Pacific's merger with Norfolk Southern highlights ongoing fears about market concentration and its impact on competition and service quality.
