Found this cool loop area map of the CTT from ca. 1898 on the internets recently...
Bruce Corzine: Wow did not realize how much rail was located just east of the river.
This is a very cool map, cannot tell from the map, did the rail yard extend north of Madison, or is this all at the south end ending around LaSalle st. And Jackson?
Dennis DeBruler: You can download the full 10546 x 6883 resolution from here:

Let's see how much of that resolution Facebook retains.
Update: it is 2048 x 1337 and the key is easy to read.

On the east side of the river, it did not go north of Van Buren.
