The AQKY container twin articulated wagons, were converted from 63' AFKX flat wagons by Australian National Railways in 1989. These were originally SFKX flat wagons, built by South Australian Railways Islington workshops. 18 units were built for standard gauge running, passing to Australian Railroad group on privatisation, and now run with QRNational/Aurzon, coded QQPY. (see photo link).
To build a set of these, you need two Steam Era Models FQX wagon kits. All that really is going to be used are the decks and head stocks. These are cut down to 144m in length, capable of carrying a 40' container each. The side sills are fabricated from strip of 0.15x0.08 glued to 0.04x0.08, flush along one edge.
The underframe needs slight modification, as the bogies on the SFKX are about 3mm further back than on the FQX. The centre sill frame needs to filled in right next to where the bogie screw hole is, with some scrap plastic, and once dried, drilled out. I used some of Orient Express Reproductions', new Roller bearing bogies (these have full brake detail), which required a spacer to correct the height. (Not needed if using the Steam Era bogies). Originally, according to plan they were fitted with AN 3X2 bogies: two 50 ton and the centre was a 70 ton ex WAGR.
Almost completed the main conversion. Just need grade control parts, air hoses and brake wheel. If building an AN version, there are shunter steps and hand grabs to add. The brake lines cannot be seen, as on my drawing (A1 1-CM-45) they run inside the main spine frame.
