The line is operated by BNSF 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 is the owner of the right-of-way, controls the line and handles dispatching from corporate headquarters in Fort Worth, Texas. Metra imposes a 70 mph maximum allowed speed for passenger trains. The BNSF Line may be the only Metra commuter line that operates via purchase-of-service agreements as of 2024 due to the Union Pacific Railroad announcing its intentions to transfer the operations and supplying of commuter trains to the Metra system itself for the routes originating from the Ogilvie Transportation Center.
When the Regional Transportation Authority (RTA) began subsidizing Chicago's commuter rail operations in 1974, Burlington Northern continued to operate its line under contract to the RTA. This arrangement continued when the RTA organized its commuter rail lines under the RTA Commuter Rail Division in 1983, later rebranded as Metra in 1985.
Today, the triple-track line is one of the busiest rail corridors in the United States. In addition to the 91 Metra trains that currently use the line, BNSF freight trains frequent the line at all hours. Amtrak's Southwest Chief, California Zephyr, and Illinois Zephyr and Carl Sandburg use the line as well, making an intermediate stop at Naperville. The Illinois Zephyr and Carl Sandburg services also stop at La Grange Road. Rail fans have coined the line as the "BNSF Racetrack".[5]
The Clyde station at South Austin Boulevard and West 29th Street in Cicero was closed on April 1, 2007 due to low ridership and its dilapidation. In the months before its closure, it was used by about 50 passengers a day.[6]
Between 2014 and 2019, annual ridership declined 7% from 16.7 million to 15.5 million passengers.[9][10] Due to the COVID-19 pandemic, ridership dropped to 3,659,617 passengers in 2020.[11][12]
