My current interests centre around small scale live steam locomotives; ones that are small enough to be made in my workshop but which still embody the principles of the full size version (which basically means they use a forced draught multi-tube boiler). Gauge 1 (roughly 1:32 or 10mm to the foot scale) is big enough to allow such designs, whilst still being manageable for somebody with only a small machine tools or limited free time for construction.
