These pages show examples of installations using my 00 scale railway format. The first time I ventured into this way of making was for the 2009 Venice Biennale, 'Souvenir' show. As I had acquired a fair amount of track for my movie making dolly it seemed natural to use this to develop its use in installation ideas. These took the form of aerial orreries that contained concepts to do with astronomy within the wagons. In the course of making these installations I was presented with a fair amount of technical problems which I am only now beginning to resolve. Though the engineering is fun to do!
