Wrong Timeline
Due to an all-day diamond replacement project at CP Canal, all Amtrak trains were detoured from the CN Joliet Sub to Metra's former Rock Island trackage. This provided a look at what a modern-day "Rocket" could look like, had the old Rock Island been able to join up with Amtrak in 1971. This is Amtrak 21, the Texas Eagle, passing through New Lenox, almost to Joliet where it would rejoin it's normal route and continue South from there.
