West Lake Corridor Project Profile

The West Lake Corridor Project is a 12.8-kilometer (8-mile) extension of the South Shore Line (SSL) in Northwest Indiana, engineered to provide direct commuter rail access to the previously underserved communities of Munster, Dyer, and Hammond. This design-build project integrates new at-grade and elevated dual-track infrastructure, four modern stations, and a dedicated maintenance facility to enhance regional mobility and connect Lake County with downtown Chicago.

Technical Specifications

The project’s alignment is strategically engineered to navigate a dense suburban and industrial corridor. A significant portion of the route is constructed at-grade, running parallel to the CSX Transportation Monon Subdivision, creating a dedicated passenger rail corridor free from freight interference. To resolve a critical conflict with existing rail traffic, an elevated structure was built to carry the line over the Canadian National (CN) Elsdon Subdivision at Maynard Junction in Munster. The project includes the construction of four new ADA-compliant stations: Munster/Dyer Main Street, Munster Ridge Road, South Hammond, and Hammond Gateway. Each station is equipped with high-level platforms, parking facilities, and passenger amenities.

Propulsion for the line is fully electric, utilizing a 1500V DC overhead catenary system. Power is supplied by three newly constructed Traction Power Substations (TPSS) located strategically along the route. The service will be operated using a fleet of modern Electric Multiple Unit (EMU) trainsets, designed for rapid acceleration and operational efficiency. A comprehensive vehicle maintenance and storage facility has been established in Hammond to support the expanded fleet, including a layover yard, a maintenance building, and a rail car wash, ensuring high reliability and availability for the new service.

Key Takeaways

• Economic Integration: By providing a direct, reliable rail link to downtown Chicago, the project is projected to catalyze significant economic development in Lake County, enhancing access to employment centers and increasing property values.
• Advanced Engineering Solution: The design-build approach facilitated an efficient solution to navigating a complex right-of-way, successfully integrating elevated and at-grade sections to bypass major freight rail lines and minimize community disruption.
• Sustainable Regional Transit: The electrified rail extension offers a sustainable alternative to highway travel, projected to reduce regional traffic congestion, lower carbon emissions, and improve air quality in the corridor.
