In addition to intercity services to Oslo and Stavanger, the eight daily trains in each direction serve as a commuter link to Kristiansand.

The station was opened on 17 December 1943 as part of the segment of the Sørlandet Line between Kristiasand and Sira.

The earthwork from the tunnels was used to build an embankment through Lyngdalen at Snartemo, on which the line and station was placed.

[1] Snartemo Station was built during the Second World War under the German-administrated expansion of the Sørlandet Line west of Kristiansand.

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.

[3] An interlocking system became operational on 17 July 1969, allowing the station to become remotely controlled from 19 August 1969.

[3] The station retained ticket sales and in 1981 the staff room was renovated.

[2] 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 yellow 210 square meters (2,300 sq ft) building is wooden with a concrete foundation.

[3] Today the station building is universally accessible and features a waiting room and a washroom, open around the clock except from 21:00 on Saturday to 07:00 on Sunday.
