Our "Gordon the Big Blue Express Lococmotive" is actually a BikeE recumbent with an extra long frame.
It's obviously blue, has a second seat for one of the kids (the tender), and a Fimo Gordon face on the front of the frame. Words can't really do it justice, so I'll try to post a couple of pics soon.
Gotta go paint now, so maybe I can get them posted this evening.
