The merger would create the United States’ first coast-to-coast rail network, spanning 50,000 miles and 43 states.

Omaha-based Union Pacific Railroad’s announcement Tuesday that it is acquiring the Norfolk Southern Railway — a move that would create the first transcontinental, coast-to-coast rail system — drew praise from Nebraska’s public and business leaders.

Union Pacific wants to buy Norfolk Southern in a $85 billion deal that would create the first transcontinental railroad in the U.S, and potentially trigger a final wave of rail mergers across the country.
