History

Nynäshamn was established as aportduring the 1860s, to allow ships to avoid theskerriessurroundingStockholm.Construction of Nynäsbanan was started by the private companyStockholm-Nynäs Järnvägs ABin 1898 and the line was opened on 28 December 1901. Initially, there was a change of trains at Älvsjö, but from 1909 onwards trains starting running directly toStockholm Central Station.To being with, one of the major traffic generators was the ferry service toGotland.In 1928, anoil refinerywas opened and the line started transporting oil.Diesel multiple unitswere introduced in 1928 and in 1935, the line started using diesel-electric locomotives. Nynäsbanan wasnationalisedin 1957, althoughStockholm-Nynäs Järnvägs ABcontinued to exist at least on paper until it was fully absorbed into theSwedish State Railwaysin 1968. The line was electrified in 1962, and in 1973 it became part of the Stockholm Commuter Rail, when at the same timeX1electric multiple units were introduced. A modernAutomatic train control(ATC) signalling system was introduced on Nynäsbanan in 1980.

From 1993 until 1996, the line was upgraded, including double track from Älvsjö to Västerhaninge. This allowed a 15-minuteheadwayon that section. Oil transport was terminated from Nynäsbanan in the 1990s. In 2007, the then-southern terminus located just besideNynäshamn Ferry Terminal(sv) was closed to allow expansion of said ferry terminal and the terminus was shortened by 500m toNynäshamn Station.Between 2008 and 2016, all station platforms on the line were extended andpassing loopswere built atHemfosa StationandSegersäng Station.

A new station calledVega(sv),located inHaninge Municipalitybetween Skogås and Handen stations, opened on 1 April 2019 after almost four years of construction. Vega was also the name of a small halt on the Nynäs Line which existed between 1929 and 1973, although it was built at a different location from the current Vega station.

In connection with the expansion of the Stockholm Norvik freight port, a siding was built from the Nynäs line towards the harbour, which was completed in April 2020.This added substantial freight traffic to the line.
