Yesterday and today this car was the lead car ahead of the normal four coaches and Amcafe consist on the 12:50 pm departure from Springfield, IL on the southbound Chicago to St. Louis train. At first glace from a block away it looked like a baggage car but it is actually a coach wrapped in the same type of covering they put on advertising busses that looks opaque from the outside but allows full view from the inside.
I Googled the car and only found an artist's image and a dark night time You Tube video. The car started in service last month to be hauled by Amtrak on football weekends from Chicago to Ann Arbor, MI since there are so many MSU alums in the Chicago area. Not sure why it was running laps from Chicago to St. Louis on a Tuesday and Wednesday.
While I am a die-hard U of Ill fan (and,boy, did we die hard this past football season) this would make an interesting decal project for one of you guys with an ALPS.
