Having enjoyed the ride behind Greenbat the thought occurred that such a loco is ideal for large scale modelling, i.e. in 7/8ths", where I like to play, and above it is still small and would be a leccy loco powered by batteries -- how prototypical is that?
See, for example, the 7/8th" model by Jeff Saxton of a Mancha trammer:



Trouble is, a quick Google hasn't tuned up a whole lot of info or pics on either Manchas or Greenbats or others.
Your help and guidance would be appreciated (stands back to avoid being knocked down in the rush).
