Union Pacific and Norfolk Southern are confirming they're in merger talks that would create North America’s largest railroad, stretching service from East to West Coasts.

Union Pacific and Norfolk Southern announced on July 29 a definitive agreement to merge, forming the first true transcontinental railroad in the United States. The combined network will connect more than 50,000 route miles across 43 states, linking nearly 100 ports and delivering coast-to-coast service for American shippers.
