Work on the Sørlandet Line through Hægebostad commenced in 1934 with work on the Hægebostad Tunnel. Unlike some of the other tunnels on the line, it was built by hand. The Kvineshei tunnel was drilled with machines, and these took over the last work on the Hægebostad Tunnel. The earthwork from the tunnels was used to build an embankment through Lyngdalen at Snartemo, on which the line and station was placed. Snartemo Station was built during the Second World War under the German-administrated expansion of the Sørlandet Line west of Kristiansand. The station building was completed in 1942. It was originally proposed to be named Hægebostad, but this was changed to Snartemo. Irregular revenue traffic commenced on the line on 17 December 1943 and the station became operative from the same day. Electric traction was introduced on 18 February 1944, ahead of ordinary traffic commencing on 1 March 1944. The station building annex was extended in 1964 to make way for a restaurant. The former telegraph room was converted to a kitchen and parts of the extension were converted to a staff room. An interlocking system became operational on 17 July 1969, allowing the station to become remotely controlled from 19 August 1969. The technical room for the interlocking was installed in the basement. The station retained ticket sales and in 1981 the staff room was renovated. The station became unmanned from 1 February 1997. The short platforms have caused the Norwegian Railway Authority to demand that they be lengthened with 2019, or the station closed. The National Rail Administration determined in 2009 that Snartesmo would be one of eighteen prioritized stations which would have their platforms lengthened and heightened the same year. The work was completed in early 2010.
Facilities
Services
The station is served by long-distance trains operated by Go-Ahead, counting eight daily services on weekdays, including a night train service. These operate from Oslo via Kristiansand to Stavanger. Snartemo is located within the outer catchment area for commuting to Kristiansand. The train uses fifty minutes to Kristiansand Station. This is less than half the time used to drive, which is further hampered by congestion during rush-hour. The station had 30,600 annual passengers in 2008. Snartemo is the only railway station in Hægebostad, and is the closest railway stations for the municipalities of Hægebostad, Lyngdal and Farsund. Agder Kollektivtrafikk operates a feeder service from Farsund and Lyngdal in connection with train services. There is a similar service northwards to Eiken. The routes must be ordered two hours in advance.
