In addition to all things NFL and 13-time NFL Champions Packers, the National Railroad Museum in Green Bay is just a stone’s throw from Lambeau Field and has a great collection from all across the fruited plain.
And not all that far away, the Mid-Continent Railway Museum near Baraboo has a nice collection also of smaller branch line-type of equipment.
And you can catch a lot of CN activity in Neenah and CP activity in Milwaukee.
