Recently came across an auction for this, a gold-plated version of the ライト付きひかり号 (“Hikari go with light”). Never seen one of these before but the seller (who seems reputable as they have a large collection of Plarail rarities) claims that there were only 10 made and given out as a prize by Neko Publishing


(according to the seller it was also originally distributed by TOMY in a Thomas box??)
It’s worth nothing that there’s another, more common gold-plated 0 Series, but that uses the newer-style mold without the light and is completely plated, unlike this one which has open windows. After doing some digging the only place I could find it was on display at a 2019 Plarail event

Even the Plarail Museum has no info on it. I think it’s safe to say this is the first time this gem has popped up online... but has anyone here seen this before or know anything about it?
