Amtrak passenger train departs Chicago

FILE - An Amtrak passenger train departs Chicago in the early evening headed south on Sept. 14, 2022, in Chicago. American consumers and nearly every industry will be affected if freight trains grind to a halt in December. Roughly half of all commuter rail systems rely at least in part on tracks that are owned by freight railroads, and nearly all of Amtrak’s long-distance trains run over the freight network.
