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.

Paramount has locked up streaming rights for the entire South Park back catalog. The media company and creators Matt Stone and Trey Parker have signed a five-year deal worth $1.5 billion. HBO Max was the previous streaming home to the show.

The combination of two large rail companies would create the first coast-to-coast network, but the deal could reduce competition.
