History.
The original station opened in 1866, when the Northern Main Line (now part of the Ostkustbanan) was inaugurated. It was originally served by trains to Uppsala. Some of Stockholm’s SJ suburban trains, which previously had their northern terminus at Upplands Väsby, were extended to Märsta in the 1940s.
In 1967, SL took over responsibility for local passenger traffic within Stockholm County, and modern commuter rail services were introduced, leading to a station upgrade. Further renovations were carried out in the 1980s.
