Excluding the major downtown Chicago terminals (like Union Station and Ogilvie Transportation Center), the busiest Metra stop is consistently the Naperville station on the BNSF Line. As a major hub for the "western suburbs," Naperville serves thousands of daily commuters heading into the Loop. Its high volume is driven by the city's large population and its status as a commercial center in its own right. Other heavily used stations include Route 59 (also on the BNSF Line) and the Evanston stations on the Union Pacific North Line. Within the downtown area, Chicago Union Station is the absolute busiest, serving as the nexus for multiple Metra lines as well as Amtrak's national network. In 2026, Metra has seen a significant shift in traffic patterns due to hybrid work; while "peak" rush hour remains busy, there has been a notable increase in midday and weekend ridership at suburban hubs like Naperville and Arlington Heights, as people utilize the rail system for leisure and regional travel. The BNSF Line remains the "workhorse" of the Metra system, consistently carrying the highest total passenger volume of any of the eleven lines.
