On my first visit to Milwaukee Wisconsin last year I didn’t notice these private cars until I was leaving on Amtrak Hiawatha. On my next trip into town I made sure to record them before I left. These private passenger rail cars are parked at Milwaukee Intermodal Station. Amtrak and Greyhound operate out of this facility. You can also catch public transportation and taxis there. Potawatomi Hotel & Casino runs a downtown shuttle that services this transit center.
I haven’t come across much information on these private rail cars. I’ve linked what I can find below. Supposedly their owner is Charter Wire Manufacturing. Didn’t see any car history on their corporate website.
