    Hi Martin,
    I’m not sure that storage would be a good idea. It’s been noted that an “off-beat” engine steams better than one with the valves set correctly, and the three cylinder Jubilee required a smaller diameter blastpipe than the two cylinder Black Five to steam, despite the two having similar boilers. I think the peak value of steam flow through the blastpipe is important, so from this point of view storage would be detrimental.
