A more technical diagram of how Chicago's wide variety of local and long distance rail lines might better serve the city, especially if new consolidated passenger terminals (seen in red) are built west (toward the top of the diagram) and south (toward the left of the diagram) of downtown. A key to the diagram is on the left side of the bottom of the slide. It can be more easily read by using the zoom tool.
