With thanks to every one here, I got hold of some plans from NZ rail & loco society, It seams they might be the last ones.
I then sent them off to Allen at Worsley Works out of the UK.
Allen has come back and we are now starting the first etch.
Im not sure on how much details will be on each of the wagons.
power car, Buffet car and the 2 diffrent style of sleeping cars.
I would like to have a full train of about 12 running plus some to have on a siding.
Now I just hope not to get a job and have it stop all this model making.
More details as and when we get them.
Pete
