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.

When Union Pacific and Norfolk Southern announced their merger deal Tuesday to form “America’s first transcontinental railroad,” it puzzled some who recalled the golden spike driven in 1869 at Utah’s Promontory Summit. That last spike only connected two railroads from Omaha, Neb., to Sacramento, Calif.

Union Pacific is seeking to buy Norfolk Southern in a deal valued at $85 billion in a merger that could trigger the final wave of railroad mergers across the country.
