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.

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

Norfolk Southern has significant infrastructure and history ties to Petersburg. Will its merger with Union Pacific untie those ties in any way?
