That enabled the yard to be enlarged, by providing two long sidings parallel to the main running line in the Down direction, with a connection for Down trains at the end of the platform. The sidings were brought into use in December 1914. In 1921, the station became a depot for gravel from the Gherang pits, which were located on the short Wensleydale branch line. Other industries along the nearby Barwon River used South Geelong as a base to receive their supplies. Seven years later, on 20 June 1928, Geelong - South Geelong was converted to miniature electric staff working, with South Geelong - Racecourse - Moriac converted on 18 September of that year. An automatic staff exchanger was provided around 1930. The crossing of trains at the station was generally avoided because of a lack of appropriate crossing facilities. Trains were only timed to cross there on special occasions, such as holiday periods. For example; on 24 December 1927, the 10.20 Warrnambool passenger service, due at South Geelong at 12.03, was due to cross the 09.35 passenger train from Camperdown, due at 12.02, and had to "wait for P3", P3 being the Warrnambool service. The train was then to wait on the Queenscliff branch line, subject to Rule 15 of Appendix VII, of the Book of Rules and Regulations. Therefore, the train, which had to wait, stood at the Up home signal. That also prevented South Geelong giving Drysdale an electric staff for trains to approach, while a train waited for a cross, or shunting trains onto the branch line, while another train was approaching. On 1 June 1931, passenger services ceased on the Queenscliff line, and, a week later, the miniature electric staff was abolished. Drysdale was abolished as a staff station, and the staff and ticket system was re-introduced between South Geelong and Queenscliff. Gates at the nearby Swanston Street level crossing were provided in 1914. In 1934, the gatekeeper was given control, via a ground frame, of two arms on "Post 3". The gatekeeper also controlled two arms above the bracket distant signal on "Post 5". That arrangement lasted until 1976, when flashing lights were provided. Boom barriers were provided later on in 2009. The former State Electricity Commission (SECV) opened a briquette depot in the South Geelong yard in 1940, with two new sidings provided. In March of that year, the siding was extended by
