NSWGR Class 422 upgrade

Tonight had me over the table contemplating how best to proceed with upgrading my old Class 422 to DCC. I had thought about replacing the current light globes with LEDs, but this might be a bit tricky with the space available above the internal plastic 'windows' insert. So before I go on the plastic cutting warpath, I might try just connecting up the current light globes to the decoder. Speaker location was decided upon above the front bogie in the body shell's roof. However I didn't have the motivation to start actually installing the decoder and speaker, so instead I started some prepatory work and made up the two black and two red front bogie additional pickups ready for installation. These are based on the pickups I designed and made up for the Class 44 mentioned in an earlier article. I will probably document how I did this upgrade to run past AMRM once I know the outcome of the Class 44 article I submitted.
