Hope this link works. Great info on the Goose Island Bridge and some great pictures from an architecture point of view.

try this otherwise cut and paste. Select Illinois, cook county , then Nort Ave railroad bridge. Also have Cortland Bridge by Finkl and others.

Railroad Model Craftsman magazine did a great, two part series about three years ago on the movable railroad bridges of Chicago.  The Milwaukee Road ones were featured along with diagrams.

You can probably contact Carstens, the publisher of RMC, can probably provide you with details and ordering information.
