The station was built by the Chicago, Lake Shore and South Bend Railway and opened c. 1908,[2] serving its namesake town and later the Indiana Dunes.

The study recommended the construction of new station at Indiana 49 and US 12, a location within 1 mile (1.6 km) of both the Tremont and Port Chester stops.

The study also recommended closing Port Chester and Pines due to low ridership, but keeping the Tremont, Ogden Dunes, Midwest Steel, Bailly, Dune Acres, and Beverly Shores stations open.

[4] A new entrance to the Indiana Dunes for bikers and hikers was added at Tremont Road, half a block from the South Shore station, in 1982.

The entrance officially opened on the July 4 weekend, coinciding with the expansion of South Shore service to the Tremont station.
