Record-high water levels are disrupting train traffic in Missouri and Illinois.
Union Pacific says two sections of track in Missouri and two in Illinois are out of service because of rising waters. The Missouri stretches span from Jefferson City to St. Louis and from St. Louis to De Soto. The Illinois stretches span from Mount Vernon to Percy and from Springfield to Nelson.
The Jefferson City to St. Louis closure has disrupted an Amtrak route, forcing passengers to be rerouted on buses.
Omaha, Nebraska-based Union Pacific says in a statement that 70 trains in the St. Louis area have been held or rerouted because of high water levels.
Crews have put rock ballast, heavy machinery and generators in several areas near flooded tracks to assist with repairs when water levels fall.
