I'm a bit disappointed. So my search for a steam engine is still not finished. May be I will get an n scale engine from Liliput or Fleischmann. For this Furuta series, there is one BR03 in 1/200 which I think was widely used during WWII in Germany. However, it's 1/200 so it doesn't fit my requirement.
Putting my requirement aside, these little engines look pretty cute and if you're a train lover, you shouldn't miss them (my 3 year old son who is a Thomas lover and he keeps asking me to give him this engine to play). There is a second series from Furuta but most of them are engines used in Japan only. For more pictures, please lick here.
Back to the Wonder Festival 2006, here are more pictures from Takara and F-Toys.
