Introduced by the Victorian Railways, most initial service of the X Class was on the standard gauge line between Melbourne and Albury, but they later operated in other areas. X31–6 entered service in 1966. Units X37 onwards were introduced from 1970 and had more powerful engines than the first six deliveries. A number of the class continue in service with Pacific National and Aurizon on standard gauge and broad gauge lines, while SCT has two for shunting purposes.
