The GT46C is a model of diesel-electric locomotive designed and built by Clyde Engineering using Electro-Motive Diesel components. A number of Australian rail freight operators purchased them from 1997: Aurizon as the Q class, FQ class, and V class. As of 2022, all 24 locomotives were owned by Aurizon following its purchase of certain One Rail Australia assets in July 2022.

Westrail

In May 1996, Westrail ordered 15 GT46Cs from Clyde Engineering as part of an order that also included nine narrow gauge S class locomotives. The order was later extended to 19.

All were included in the sale of FreightLink to One Rail Australia, and later In July 2022 Meaning Into Repaint Aurizon.
