Rarest Plarail/Tomy Trains

The chrome Fukuoka Subway train is pretty cool. I have always liked that picture of a driver on the front. Aren't there other Plarail trains that had something similar or are the ones I have seen in the Japan auctions the same?

Chinchin Densha, and the normal green belt underground train has those images too, but the image is completely different from the Tenjin Subway's.

 

Though it has been theorized that only 10 Gold Thomas’ were produced, no one really knows...
However, only 2 have ever been seen at auction. The second one is very VERY poor condition.
It was first listed separately at auction, but did not sell, and was then re-listed in a lot along with Silver Thomas and Blushing Thomas by a Japanese collector for $15,000, but again there were no bids.
It has never been offered up again, and there have been no other sightings of any others in several years.

Was there an advertisement for that Thomas? There should be some information on the number of winners.
I have seen that auction too Muddy, I think that same listing was available on Mercari in one point in time but I didn't really check when it was listed.
