Former Baltimore and Ohio passenger main line into Chicago, with passenger trains discontinued in 1971 with the formation of Amtrak. C&O former Pere Marquette passenger trains also used this route, using trackage rights over the former New York Central between Porter and Pine Jct. Amtrak later restored some passenger service, instead using the more direct Norfolk Southern routing in and out of Chicago. West of Rock Island Jct., passenger trains had used trackage rights over the Rock Island Railroad to Beverly Hills. North of Beverly Hills, a B&O line extended north to join the present CSX main line at 79th Street.

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.
