Södertälje Syd railway station

Södertälje Syd (Södertälje South) is a railway station in Södertälje Municipality, Sweden, located around 3.7 km from central Södertälje. It consists of two separate stations: an upper-level station Södertälje Syd övre (Södertälje South Upper) for regional and intercity trains and a lower-level station Södertälje syd undre (Södertälje South Lower) for Stockholm's commuter trains. The upper station is located on the 2 km long Igelsta Bridge, while the commuter rail station is at ground level beneath it.

Regional and intercity trains operated by SJ, Mälartåg, Snälltåget, and VR stop at the station, with routes connecting cities such as Stockholm, Gothenburg, Malmö, Copenhagen, Oslo, Linköping, and Eskilstuna.

The Stockholm commuter rail service to central Södertälje primarily operates from Södertälje Centrum station, which has significantly higher passenger numbers. The commuter train service to Gnesta also stops at Södertälje Syd (lower) but has a relatively low frequency. In 2019, only 300 passengers per weekday boarded commuter rail services at Södertälje Syd, making it the third least-used commuter rail station in Stockholm County, ahead of only Hemfosa and Krigslida on the Nynäs Line. However, a considerably higher number of passengers use the station for regional and intercity travel.
