Winter storm live updates: Travel disruptions expand as extreme cold blasts south ahead of developing blizzard

The massive storm sweeping through much of the United States is prompting intercity train cancellations through Christmas Day.

Amtrak is suspending some trains through Sunday on multiple Midwest and cross-country routes. These actions, the railroad said, are taken “with abundant caution and in consultation with state transportation departments, host railroads, emergency managers, and weather forecasters.”

Service is canceled on long-distance routes that originate or end in Chicago, including the Empire Builder, the Cardinal, the Capitol Limited, the Southwest Chief and the Lake Shore Limited.
