A request was made by a Shapeways customer to upscale the N Scale version of this generator to HO scale. This load is for a PRR FD2 model, I think there are brass and RTR versions in HO.
This simple to clean, assemble and paint model is now available for purchase at the Keystone Details HO! section of the shop:

This is what it looks like in N Scale, model and photo by Josh Surkosky:
