I'm planning a 5 segment trip: Quincy, Galesburg, Denver, Chicago, NY, Tampa departing Nov 19, with 2 nights in the ill-fated 32 car on the California Zephyr. When I received that dreaded robo call from Amtrak, I feared he worst. But it merely notified us that the short QCY-GBB segment would be bustitution.
The only information I could find was an article in the Whig, Quincy's newspaper. It stated "Amtrak is cutting train service to and from Quincy in half through the middle of January, according to an Amtrak spokesman." The morning northbound Illinois Zephyr 380 and morning southbound Carl Sandburg 381 are being cut.
Just in time for Thanksgiving and Christmas holidays.
