of the original Tonsley station site, and cross Sturt Road, Laffer's Triangle and Main South Road, before terminating at Flinders station. Clovelly Park station would be replaced by a relocated Tonsley station as part of the extension project. The original Tonsley station was closed after the final service on 28 June 2019, allowing construction of the rail overpass at the station site. Services terminated at Clovelly Park station until the extension was completed. Built concurrently with the adjacent Darlington Upgrade for the Southern Expressway, major works took place from July 2019 to October 2020. The line was temporarily closed after the last service on 20 November 2020 for the extension to be commissioned, and fully reopened on 29 December. The operating hours of the line were expanded to include weekday nights and weekends. Before that, the line only ran between 6:30 am and 7:30 pm on weekdays, and was closed on weeknights and weekends.

Before the extension to Flinders, services operated between 6.30 am and 7.30 pm on weekdays only. Services were only extended to operate during weekday off-peak periods in 2004. Stations between Adelaide and Woodlands Park are also served by Seaford line trains, and stations between Adelaide and Goodwood are also served by Belair line trains. Prior to 2014, most trains were operated by 3000 class railcars, augmented at times by 2000 class railcars. Following the electrification of the line, the latter were no longer authorised to operate on the line and they were retired from service in 2015. The line is now operated by A-City electric multiple units.
