The east end is Union Station in downtown Chicago. The line traverses Chicago and its western and far western suburbs to Aurora. BNSF Railway operates it under a "purchase of service agreement" with Metra, inherited from Burlington Northern. While Metra owns all rolling stock, the management and crews are BNSF employees. BNSF controls the right-of-way on the line and handles dispatching from corporate headquarters in Fort Worth, Texas. The June 2007 timetable shows a 70 mph maximum allowed speed for passenger trains.
