During 2000, a program commenced to convert the remaining VHDX wagons to VHJX class for gypsum traffic between Nowingi - Gherinhap and Waurn Ponds. The conversion involved removal of the roof, repainting into Freight Australia colours and recoding. As at 2005, the number group was VHJX 203-207 and 209-210. Following the cessation of the Nowingi traffic in late 2004, the wagons have been seen in use on the quarry train between Kilmore East and Westall.
