The Monon Corridor is an 8-mile southern extension of the South Shore Line’s main Lakeshore Corridor, which is currently under construction. This new line will connect north Hammond to its final stop at the Munster/Dyer Station. The existing main line will continue to be called the Lakeshore Corridor.
Before service officially begins, test trains will operate along the new route to ensure all systems are running safely and efficiently. These test trains will not carry passengers and will help train onboard crews and dispatchers in preparation for the start of service.
The project is anticipated to be completed in the first quarter of 2026, though this timeline may be adjusted based on construction and testing progress. The South Shore Line will continue to share updates and keep communities informed as the Monon Corridor approaches its opening day.
