Amtrak Crossing the Illinois River 

Combined AMTK 4 & 6 crosses the Illinois River at Chillicothe due to a coal train derailment near Naperville, Illinois. Amtrak No. 4, the Southwest Chief (Los Angeles CA to Chicago IL), and Amtrak No. 6, the California Zephyr (Emeryville CA to Chicago IL) were combined at Galesburg and detoured along the BNSF Chillicothe Subdivision.
