[3][4] On 11 November 1912, Lidcombe became a junction station, with the opening of a deviation of the Main South line to Regents Park.

[4] In 2007, the Lidcombe Station Upgrade project removed the Walter Bowmer Memorial Reserve and Memorial Plaque[6] (dedicated by Auburn Council in 1986 to former alderman Walter Bowner, who served in the 1950s[7] and had a hairdressing salon at the site) located on the western end of the station adjacent to Tooheys Lane.

The station works as part of the CityRail Clearways Project completed in 2010 featured a new platform for terminating trains from the Bankstown Line.

A new train timetable implemented in October 2013 resulted in the discontinuation of all Bankstown Line to City via Regents Park services and discontinuation of almost all trains to Liverpool via Regents Park prompting a community campaign to reinstate lost services.

[8] In 2020, the NSW Legislative Council Inquiry into Sydenham to Bankstown line conversion questioned the need to terminate services at Lidcombe, and recommended that both Bankstown to City via Regents Park and Liverpool to City via Regents Park services be reinstated.
