The thrust of the story is that due to a major dispute between Amtrak and the freight railroads, Amtrak cannot expand. In particular, Amtrak has been stymied building the Gulf Coast route (New Orleans to Mobile) which is considered a bellwether for further expansion plans.
Excerpts from the lede (not behind a paywall):
"Amtrak has money to expand, but it doesn’t own the railroad tracks. A stalled effort along the Gulf Coast is a test of its ability to grow."
"Any expansion in Amtrak’s territory, which has remained nearly unchanged during its five decades, would boost pressure on freight companies and add trains to shared tracks at a time when the industry is under scrutiny over supply chain disruptions."
