Iron Duke from an Emily

What a strange twist with the way it is powered, but I'm sure I know how it was done. The whole drive unit can't be adapted to Emily's chassis as is, so he took out the actual motor and put it in the loco after adding a gear to the unpowered drivers. That would also explain how it's much quieter than any Flat drive. Hopefully that means it would be possible to convert most tender drive engines to be loco drive the same way (which would be great news for those who don't like them). One big downside is having no transmission would reduce their performance and prevent free wheeling, but the latter is only a minor issue. Still impressive.
