Bit more progress on No 4. The ‘box’ that comprises the main structure (the panelled sides will be stuck on as an overlay) is done, as is the chassis. Last year I built a TPO which went ok but I have become increasingly dissatisfied with the finish. And its running gear involves some £30 worth of brass and steel - it needs to earn its keep! So last night the TPO was grounded and the rolling chassis (compensated Alphagraphix) transferred over. I also had to cannibalise the brake gear a bit as SLNC coaches only had brakes on the middle wheels and one end...
