CTA Surface System History presented by the Illinois Railway Museum

IRM Logo                 CTA Logo

The CTA map index was researched and devised by Roy Benedict and Bob Heinlein. Thanks to both these gentlemen, we are able to benefit from the hard work and dedication.

Dates on Pre-CTA maps have been gathered from research of the printed map itself as well as information from experts.

"Front Page" is identified as the side with the major map. "Back Page" is the opposite side. NOTE: Some full maps are around 10mb.
