Monon Corridor
(Formerly West Lake Corridor Project)
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.
New Monon Stations
The new Monon Corridor includes four new stations with high-level platforms:
Hammond Gateway
Near Gostlin Street and Sheffield Avenue in Hammond
Monon Corridor Service
In preparation for the launch of the new Monon Corridor service, the railroad will provide fact sheets, release instructional videos, and promote information to help commuters get familiar with the new service.
*Time is built into the schedule to allow passengers sufficient time to make their connection.
The passenger timetable, App, posters, and other information sources will clearly note the Shuttle Trains that require transfer.
Only one ticket will be required for the transfer.
Safety
A public safety campaign will roll out ahead of testing to remind the general public that trains are in the area, and to be mindful and safe at all grade crossings.
The South Shore Line is also currently collaborating with the national Operation Lifesaver railroad organization to visit schools and provide safety education to children throughout the communities adjacent to the corridor.
Quiet Zone
The City of Hammond and Town of Munster jointly applied for a Quiet Zone with the Federal Railroad Administration (FRA), which is currently under review. NICTD anticipates the Quiet Zone will be approved by the FRA in advance of Revenue Service.
Communities should be aware that engineers may sound their horns during the testing and commissioning phase. Train engineers may also sound the horn at their discretion at any time due to safety concerns.
