By 1899, 3 tracks existed as far north as Rose Hill, later extended to Wilmette, removed in 1984. The center track, though with bidirectional signaling, was assigned a current of traffic according to the time of day, with signals apparently not set up to protect against opposing movements.

A bridge reconstruction project is underway between Clybourn and Evanston, resulting in changes. A third track to the west was removed in 1984. And the first phase of the bridge reconstruction project has involved construction of a new track and bridges at the location of the removed track.

(*The former Chicago & North Western terminal at 500 W. Madison St. has been known by many different names through its history. Including "North Western Station", "Madison Street Station", "Chicago Passenger Station", "Metra Passenger Terminal", and currently "Ogilvie Transportation Center". This lack of a consistent name has resulted in many confused passengers over the years.)
