Milwaukee District North is a commuter rail line in the Chicago metropolitan area operated by Metra. It runs from Chicago Union Station northwest to Fox Lake, serving suburban communities in Cook County, Illinois and Lake County, Illinois. The route follows historical trackage associated with the Chicago, Milwaukee, St. Paul and Pacific Railroad and interchanges with multiple regional transportation corridors.

Route description

The line originates at Chicago Union Station, traversing the BNSF Railway and Canadian Pacific Kansas City influenced corridors into the Chicago Loop before branching onto the former Milwaukee Road mainline. It proceeds northwest through River West, Elmwood Park, Riverside, and Forest Park, then continues past suburban nodes including Northbrook, Glenview, Waukegan-adjacent communities, and terminates at Fox Lake. The line parallels portions of Interstate 94 and intersects with Metra's Milwaukee District West at shared trackage near Clybourn station. Physical characteristics vary: double-track segments in densely trafficked zones reduce to single-track territory north of Glenview; sidings and passing loops at Wilmette station-area facilities enhance capacity. Freight movements are coordinated with Canadian National Railway and Union Pacific Railroad through trackage rights and dispatching agreements.

History

The corridor traces to the 19th century expansion of the Chicago, Milwaukee, St. Paul and Pacific Railroad (the "Milwaukee Road") and predecessor lines established in 1882 to connect Chicago with Milwaukee. Federal-era regulation shifts involving the Interstate Commerce Commission affected trackage rights and mergers through the 20th century, culminating in consolidation under Canadian Pacific Kansas City-influenced ownership of regional mainlines. Declining intercity passenger rail in the mid-1900s and suburbanization led to increased commuter demand; Regional Transportation Authority initiatives and the creation of Metra in 1984 formalized commuter operations. Infrastructure investments in the late 20th and early 21st centuries—including signal upgrades influenced by Positive Train Control mandates and station rehabilitation funded through state and federal discretionary grants—modernized service, while periodic negotiations with freight carriers addressed capacity constraints.

Operations and service

Metra operates weekday peak, off-peak, and weekend schedules on the line with express and local patterns to balance trip times for commuters traveling to Chicago Union Station and reverse flows to suburban employment centers. Timetables coordinate with connecting services at transfer points such as Glenview station, Northbrook station, and Cary for onward connections to Pace bus routes and regional Chicago Transit Authority services at downtown terminals. Crew bases and yard facilities are located near Glenview and at a northern layover facility near Fox Lake, supporting daily rolling stock staging. Dispatching integrates Metra control with freight dispatcher zones from Canadian Pacific Kansas City and Union Pacific Railroad under joint operating agreements.

Stations

Stations along the route include hub and local stops such as Chicago Union Station, Clybourn station, River Grove station, Elmwood Park station, Northbrook station, Glenview station, Devon, Waukegan station-area stops, and Fox Lake. Facilities range from high-traffic intermodal complexes with waiting rooms and ticketing at Glenview station and Chicago Union Station to smaller shelter-equipped platforms at suburban stops. Accessibility improvements compliant with the Americans with Disabilities Act of 1990 have been implemented progressively, with elevators, ramps, tactile edging, and enhanced parking at priority stations. Transit-oriented development has emerged around several stations, notably projects near Glenview station and Northbrook station focusing on mixed-use redevelopment.

Rolling stock

The roster primarily comprises bi-level coach fleets built by Bombardier Transportation and Nippon Sharyo for Metra commuter service, typically hauled by diesel-electric locomotives such as models from EMD (Electro-Motive Diesel) including EMD F125-class replacements and rebuilt EMD F40PH-heritage units in previous eras. Cab control and cab car operations enable push-pull service to minimize terminal dwell; passenger amenities include ADA-compliant seating, onboard HVAC, and bicycle storage policies aligned with Metra rules. Maintenance and overhaul cycles occur at Metra-owned yards with periodic mid-life refurbishments financed through state appropriations and federal transit grants.

Ridership and performance

Ridership patterns reflect commuter-centric peaks with weekday inbound morning and outbound evening surges; weekend service supports leisure and reverse-commute movements to destinations near Fox Lake and recreational lakeshore areas. Performance metrics tracked by Metra monitor on-time performance, mean distance between failures, and passenger load factors; targeted investments in signaling and dispatching seek to improve punctuality. Ridership trends are influenced by regional employment at hubs in the Chicago central business district and suburban corporate centers in Northbrook and Glenview.

Future plans and upgrades

Planned improvements emphasize capacity enhancement, reliability, and customer experience: proposed projects include additional double-track segments north of Glenview station to reduce single-track bottlenecks, station accessibility upgrades at priority stops, and advanced positive train control refinements in coordination with Federal Railroad Administration grant programs. Discussions with Canadian Pacific Kansas City and regional freight stakeholders consider temporal separation and infrastructure funding to support more frequent peak and reverse-peak service. Transit-oriented development and multimodal integration proposals around stations aim to increase ridership and regional connectivity.
