Looks like they are back in stock at Hobby Search Hank. I was fortunate enough to get in on the initial pre-order a couple months ago. http://www.1999.co.jp/eng/10298493
I am not sure if the Japanese do the Zodiac but they are constellations I think. In real life this is a one of a kind train. Also interesting, after looking this up after you mentioned the Zodiac, The four coaches are restored diesel powered which would explain about the 2 detailed front and rear cars and could run by themselves. What I don't see is different shades of blue. Wonder if there is an explanation from Tomy somewhere? It looks like the real train is really quite new starting in April 2014. I would imagine that this set might be a Limited Edition to go with the new real train. Check out this link for pictures and info on what is in those 4 cars. https://en.wikipedia.org/wiki/SL_Ginga
