Looks like you're already "doing it right" at the moment. How difficult was it to rebuild Emily's chassis to suit him?
I didn't recall you having Wooden Railway as well. Are you using the Wooden Fergus for reference only, or will parts from it be used on the custom? If so, I'd rather the whole smokebox be carrried over and not only the face. I'd also suggest you take a battery truck (with a switch) from an old Talking/RC engine, fit a motor (not drive unit) to Fergus and wire him to it so he could be loco driven. Ideally a grey one with stones like the one from early FP Talking Thomas.
