Between Chicago and Porter IN (CP 482), Amtrak trains use the main line now owned by Norfolk Southern. Between Porter and Kalamazoo, the line was originally the Michigan Central Railroad, and through mergers subsequently became part of New York Central, and then Penn Central. In 1976, when Conrail was formed to take over Penn Central and other bankrupt northeastern railroads, this segment was not included in the Conrail plan, due to a lack of freight traffic. Amtrak thus had no choice but to assume direct ownership of this segment.

1 track, CTC in use, controlled by operator at Lake Street Tower/Chicago Union Station.
Information is subject to change, and is based on observations, along with information from employee timetables.
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
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.
