In northwest Indiana, the South Shore Line announces the completion of the West Lake Corridor project line extension and opening of train service on the new Monon Corridor. Along with the opening of the new line, the South Shore Line says it will be implementing a new train schedule effective Tuesday, March 31, 2026. This new schedule is the result of the capital improvements made to the South Shore Line infrastructure by the Monon Corridor (West Lake) Project.

The new Monon Corridor service, an eight-mile southern extension of the commuter rail, will not begin until midday, March 31, 2026.
The first train running on the Monon Corridor will move southbound (eastbound) from Hammond Gateway Station toward Munster/Dyer Station at 11:45am CDT. The first northbound (westbound) train on the Monon Corridor will be a shuttle train departing Munster/Dyer at 12:35pm CDT. Passengers riding the Monon Corridor shuttle trains wishing to continue westbound into Chicago must disembark at Hammond Gateway Station and transfer to the main South Shore Line’s Lakeshore Corridor platform. Lakeshore Corridor service will operate on its new, regular weekday schedule beginning March 31, 2026.
The Monon Corridor is the South Shore Line’s first branch line. Hereafter, the train service will be referred to as two corridors: the Lakeshore Corridor, running from South Bend to Chicago, and the Monon Corridor, running from Munster/Dyer to Chicago. New stations on the Monon Corridor include Hammond Gateway, South Hammond (173rd St), Munster Ridge, and Munster/Dyer. Passengers will not need a separate ticket to travel between the Lakeshore Corridor and the Monon Corridor. Passengers should choose their departure station and arrival station as they normally would. The system will issue one ticket for the trip.
