It serves 15 stations towards its terminus in Waurn Ponds, a southern suburb of Geelong, via the Regional Rail Link.

[2] Following its sale, the line was progressively extended south-west, to Winchelsea in 1876, Colac in 1877, Camperdown in 1883, Terang in 1877, and lastly to Warrnambool, Dennington, and Port Fairy in 1890.

[5] There have long been calls to electrify the line, but plans were put on hold by the State Government in 2002,[7] with diesel locomotives and railcars utilised instead.

[11] Recurring issues on the line included poor communication,[12] commuters worried about losing their jobs in Melbourne due to delays,[13] and overcrowding.

[15] The Regional Rail Link included two new stations to be served by Geelong V/Line trains: Tarneit and Wyndham Vale.

[21] The current V/Line timetable has weekday services operating approximately every 20 minutes from Southern Cross to either South Geelong or Waurn Ponds in an alternating pattern.

According to the current timetable:[22] Weekday peak services towards Southern Cross typically originate at either South Geelong or Waurn Ponds in an alternating pattern, and most stop all stations.

[23] The 2018 Western Rail Plan identified a need to electrify the line up to Wyndham Vale, which would significantly resolve the overcrowding problem due to the fact Metro's trains can hold more people than V/Line's.

[24] Geelong services used to run on the same tracks as Metro's Werribee line until the Regional Rail Link was opened in 2015, diverting trains along a new alignment completely bypassing it.

[25] In 2023, the Federal Government cut funding to various infrastructure projects, resulting in Geelong Fast Rail being shelved.
