As you can probably tell, I spent some time in Chicago this week. I stopped by the real Zephyr to go inside and check out the train set itself. I see why this has been reproduced so many times. It is just gorgeous in person. This really is a spectacular train by any measure. If you have not been to the Museum of Science and Industry in Chicago, just this alone makes it worth the visit. By the way, they also have a pretty nice train display there (with trolleys and some great reproductions of classic trains) as well as a huge O gauge layout.
Oh yes... And who can forget the "L".
