Information is subject to change, and is based on information from the CORA (Chicago Operating Rules Association) guide dated 2001, along with some observations, and Google satellite imagery.
The following colors are used to indicate types of operation:
BLUE - manual interlocking
RED - centralized traffic control (CTC) or bidirectional signals
GREEN - automatic block signals (single direction, current of traffic)
BLACK - unsignaled
Thin lines across tracks indicate signals. In CTC or bidirectional signal territory, signals usually exist for both directions at all locations, except at interlockings where the signals usually are only in the direction entering the interlocking.
