HAMMOND, Ind. — South Shore Line commuter service on its new Monon Corridor branch is set to begin Tuesday, March 31, according to the Northern Indiana Commuter Transit District.

The 8-mile right-of-way, a segment of a route that once hosted Monon’s Thoroughbred to Louisville, Ky., and the Tippecanoe and Hoosier to Indianapolis before rails were ripped up, is set for its first revenue departure from the Hammond Gateway Station for Munster/Dyer at 11:45 a.m. That will follow a ribbon-cutting ceremony and inaugural run for NICTD, state, and local officials at the Hammond station at 10 a.m.

The electrified Monon Corridor, known as the West Lake Corridor during construction, connects at Hammond Gateway with the South Shore’s Chicago-South Bend, Ind., main line. That line has been re-designated as the Lakeshore Corridor.

The new route serves an area that has never had efficient public transportation options for commuters who live in Indiana and work in Illinois. Attracting more residents is the principal reason the nearly $1 billion project was financially supported by the state of Indiana, which contributed about $300 million to construction. A $354 million Federal Transit Administration grant and additional funds furnished by local taxing authorities paved the way for a Munster groundbreaking on Oct. 28, 2020.

Once targeted for a May 2025 opening, completion of the project was pushed back by challenges in relocating utilities; rebuilding the adjacent bike and hiking trail with new flyovers; constructing four stations and 16 bridges over railroads and Interstate 80-94; and unforeseen obstacles following the installation of track and catenary.

Dynamic testing to comply with Federal Railroad Administration and FTA requirements began in December 2025 [see “South Shore stages …,” Jan. 3, 2026]. Simulated schedules were staged early last month [see “News photos: South Shore runs …,” Feb. 5, 2026].

Passengers boarding at South Hammond, Munster/Ridge Road, and Munster/Dyer will have 17 trains each way on weekdays and 10 round trips Saturday and Sunday. The initial timetable calls for six weekday round trips offering a one-seat ride between the Monon Corridor stations and downtown Chicago without stopping at Hammond Gateway. Five of these are carded in the morning rush hour into the city and evening outbound. The other serves reverse commuters, leaving Chicago at 6:02 a.m. and returning at 4:42 p.m. from Munster/Dyer.

The direct service is scheduled to take 50 to 55 minutes from endpoints. The rest of the day, Monon Corridor shuttle trains will connect with Lakeshore Corridor trains at Hammond Gateway; connection times are usually about 14 minutes but waits for off-peak transfers can be longer. Monon Corridor trains arrive and depart on a separate platform.

Because direct rush-hour trains don’t stop at Gateway, travelers connecting from stations on the Lakeshore route from Gary, Miller, Michigan City, or South Bend must do so at Hegewisch, the first station to the west. Extra time for the connection must be allowed since trains from Chicago may depart up to four minutes earlier than times listed. Fares are comparable with NICTD’s Lakeshore Corridor trains.

Retiring NICTD President Mike Noland announced the Monon Corridor debut last week in what he characterized as a “final letter” to customers. He also recounted the challenges and successes during his nearly 12-year tenure. His successor is David Dech, who formerly led Florida’s Tri-Rail [see “Dech named new president …,” Jan. 27, 2026].
