All of the surviving structures of the Vulcan Vale Railway are kindly displayed by one of Rick's sons, Grant. He kindly displays them in the window of the shop front he owns in Avoca. We were lucky enough to be able to borrow these beautiful models for the 2017 Australian Narrow Gauge Convention. I had all the displayed models at my place for about 6 months to do some gentle restoration work on them and assemble the display bases they now sit on in the shop window (prior to that they were just stacked up on books and bricks).
It was certainly a privilege and an honor to have these models in my care during this period, and be able to study and admire Rick's fine craftsmanship up so close. There is some incredibly clever engineering in many of these structures that people would only appreciate if able to see the back of them or turn them upside down. I never got the chance to see the layout in operation, so to spend this time with these models was the next best thing.
As for their future, I hate to think what they would be worth...they are museum grade models. Rick's son, Grant, is quite a capable modeller himself, but doesn't have much time to commit to the hobby. As far as I'm aware, the models are just planned for private display, with no intention to see them built within a working layout again (I don't think any new layout would do them justice).
