I've found another top quality Thomas project by a parent as opposed to someone in the fandom. Rovanite, who normally specializes in sculpting and building things like cosplay props and miniature figurines, took a TrackMaster Bash and turned it into Millie for his daughter. As with the Wooden Railway Steamworks by GNK108, the only "problem" (if you can call it that) is that it's overly detailed and the cab and funnel exceed the "loading gauge". If anything, it looks like it should be used with Bandai's Departing Now range. Nevertheless, he did an incredible job on her.
