Guys-
I know that this is primarily a Chicago Switching website but look for new content over time in the Milwaukee section. I just added a sequence of new photos of the former UP (C&NW) Green Spur on Milwaukee's South Side. Pocket sized branch line but with an interesting mix of neighborhoods and parks through which it ran. Included are links to other sites showing UP trains on this branch before the tracks were taken up and historic aerial photos.
