Amtrak's High-Speed Rail Revolutionizes Travel Between Chicago and St. Louis.

Amtrak is speeding up trains and eliminating the need to transfer at some stations in the Midwest, with higher-speed trains already running between St. Louis and Chicago. Upgrades along some 300 miles of tracks cost an estimated $2 billion and have been in the works for years. Federal lawmakers have allocated some $66 billion for improvements to passenger and freight train lines over the next five years as part of the bipartisan $1.2 trillion Infrastructure Investment and Jobs Act signed by President Joe Biden in 2021.
