I got the word Joella from the bottom of the chassis and just assumed. whoops.

Upon further inspection, the Joella must refer to Joella Productions which I assume (there I go again) is the company that made the show? And...geesh...there is a sticker on each side of that engine that says Bakerloo...what a dolt I am, I am.
