I will let the Caboose to a new driver, so I will list some train-related stuff that occured during the trip.
I saw multiple CTA trains (photo) and some other passenger and cargo trains in Chicago.
I heard a few trains whistleling in Madison, but didn't see any of them this time.
One fellow had retired in Ashland (photo). It used to be quite a giant at its time!
I went home to Jyväskylä by Pendolino train and regional train (diesel-powered, photo). I will add a couple of photos from Jyväskylä later.
