With Chicago being the railtown it is, and was, you can be sure it has more than it's fair share of towers to control all of those trains. Even
with all of the consolidation and mergers that have taken place over the years, a great majority of them are still around to put into your pictures.
Denver Todd for doing most of the legwork!
Aerial shots were taken from
www.bing.com/maps. The screen-shots from Bing are made with Snagit, a
Techsmith product... a great tool if you have never used it!
Pictures and additional information is always needed if anyone feels inclined to take 'em, send 'em, and share 'em, or if you have something to add or correct.... credit
is always given! Contact info is here.
