Learn About the Subway Tunnels

IRM is an educational organization, and our members are always glad to share their expertise with others.  Often, this is knowledge you can't get anywhere else!

He is also an active member of the Illinois Railway Museum at Union, Ill., (nee the Illinois Electric Railway Museum at North Chicago, Ill.) and a Life Member of the American Public Works Association.

Is there any chance of getting his talk posted on YouTube for those of us unable to travel to hear it?

Sorry, the City of Chicago still maintains a valid copyright on the films. With out the films the talk would not be very much. I do have some permissions to use the films but under no way can I post them.
