Situated 36.5 km north of Stockholm C, it lies on the East Coast Line (Swedish: Ostkustbanan).

[2] Märsta Station originally opened in 1876, ten years after the inauguration of the Stockholm–Uppsala railway line.

The older part of the station serves SJ Regional Trains and consists of a platform with two through tracks.

[6] In connection with the 2014 Swedish general election, both the Social Democrats and the Moderates declared that Märsta station should be rebuilt.

Plans for the station include the redevelopment of the Märsta railway yard, new entrances and platforms, expanded passenger waiting areas, and improved accessibility between SL and SJ trains.
