It is located 45.3 km from Stockholm Central Station on the Mälaren Line.

Regional trains stop at Bålsta Station on the Gothenburg-Hallsberg-Västerås-Stockholm route.

At the southern end of the main platforms there is an entrance and ticket hall to the SL commuter train section which consists of a track and a side platform.

The current station was opened in 1996, as part of work to expand regional train traffic on the Mälaren Line.

In 2001, Stockholm's commuter train service was extended to Bålsta, and it is now the terminus of SL Line 43.
