At the sharp curves at North Canal Street in downtown Chicago, an outbound Metra Milwaukee District West Line train headed for Elgin passes Amtrak's Phase II Heritage unit, P42DC #66. "Phase II" is the second paint scheme used by Amtrak, and number 66 was painted this way to commemorate Amtrak's 40th anniversary. The unit is pushing a Hiawatha Service train into Chicago Union Station from Milwaukee, Wisconsin.
