Commuter rail system in Indiana and Illinois
The South Shore Line (reporting mark NICD) is a commuter rail system operated by the Northern Indiana Commuter Transportation District (NICTD) between Millennium Station in downtown Chicago, Illinois, and Northwest Indiana, United States. The system consists of two service lines: the Lakeshore Corridor and the Monon Corridor. It primarily serves the Indiana portion of the Chicago metropolitan area. The initial line was built in 1901–1908 by predecessors of the Chicago South Shore and South Bend Railroad, which continues to operate freight service. Passenger operation was assumed by the NICTD in 1989, who also purchased the track in 1990. The South Shore Line is one of the last surviving interurban railroads in the United States. In 2025, the system had a ridership of 2,029,900, or about 7,100 per weekday as of the second quarter of 2026.
