Conrail #23660, location unknown, August 1981, photo by Chuck Zeiler I'm pretty sure this was shot in the Chicago area. It's a caboose with obvious heritage. I wish I had more info about this caboose, and I'll bet there's a lot of stories this caboose could tell. Anyway, if anyone has any information about this caboose, please post a comment here. Thanks.
Eureka, I found a link with a clue.
