How to Scratchbuild your own Overhead Catenary System.
I am indebted to Alastair Thomson for providing me his notes and experiences on constructing the essential of Modern Image Modelling.
Introduction from Alastair:
I built my own 'OO' scale system from scratch using little more than polystyrene 'H' columns and standard electrical cable from a 'DIY' store. Construction was simplified by standardising the design which can accomodate spanning multiple tracks, station platforms and junctions. It is loosely based on ECML which tends to have cables for support in preference to the lattice structures seen elsewhere. Inevitably, there had to be compromises in scaling down to ensure functionality on a small scale, and yet simple enough to be built in a reasonable timescale. Spacing between masts is 40-50cm with curved wires around bends giving a reasonable appearance but still giving the conductor wires enough support and rigidity.
