The railway was used to transport timber from forests in the South West to the company's jetty at Lockville using the Ballaarat steam engine.
Timber Company constructed the 12-mile (19 km) long Ballaarat tramline in 1871 between Lockville and Yoganup.
[3] The tramline's name originated from the locomotive that operated on the railway, named Ballaarat by the Mayor of Melbourne on the original spelling of the Victorian town of Ballarat where the locomotive was constructed.
[7] A plaque and locomotive wheel commemorating the Ballaarat tramline is located at Wonnerup House.
[3] The Ballaarat steam engine now resides in Railway House, attached to the Visitor Centre on the Busselton foreshore.
