Almost 20 years
SCT started running Melbourne Perth railfreight services in July 1995 so this year will mark their 20th anniversary. The operation started off using hired in locomotives, crews and rolling stock form various government operators.
Over the last 20 years the company has transitioned to the point where it now owns all its own locos and rolling stock fleet and employs its own crews.
On 4 February 2015, EMD-powered units SCT003/SCT007 are a few kilometres from Port Augusta with their transcontinental 2PM9 Perth to Melbourne service.
