Jarrah:
Look for Robin's (Matthyro) threads. He builds the most amazing buildings from scratch -- ultimate scratch: breakfast cereal boxes. (I think he's come into a legacy recently because his last project was in wood.) Buildings are a good start because most of the surfaces are flat and the joints are straight. Also, they don't have to stay on the track.
What does Tasmania have for trains? My wife has a cousin in Hobart, but she never says anything about trains.
