C&NW (or CNW), but I have a family connection to the heritage - and now defunct - train line.
My oldest sister was an in-house counsel at the railroad ahead of their acquisition by Union Pacific. It is pretty neat that they've kept the sign up near the station as a reminder of year's past. When we built out the Babe's Lionel train this year, one of the cars that she ran was a CNW tanker car that we picked up because of my sister's tenure with the railroad. At one time the Chicago and North Western (two words, unlike the University!) was one of the longest rail systems in the country. And today? It is gone. But not the signage. In fact, if you look closely, you'll see CNW badges on some of the overpasses and on some of the freight cars running on the UP lines in the Western Suburbs. I always get a smile when I see them.
