Rarest Plarail/Tomy Trains

A universal opinion from most members on here say it's these three Plarail engines: Talk 'n' Action Diesel 10, Powerful Gordon, and Gold Thomas. The latter that several people have struggled to find online at all.

Honourable mentions to the Talk 'n' Action versions of Gordon, Henry, and Toby.

Hello everyone...please allow me to retort.
I do not believe in Gold Thomas for the following reasons:
1.I believe it is a one-off or a mod.
2. I have not seen any acompanying box to show it was sold to the general public.
If we are talking about an American speaking Talk'n Action Diesel 10, I have never seen even an image of one (let alone, and most importantly HEARD one), nor any literature, or box art...also ALL the voices for each T'nA train of each language are credited to the actual actor who provides them. NO ONE has ever been credited with providing a voice for an American speaking D10 either, so I also do not believe it exists.
NOR DOES MONTY!!
There are 2 very nice Powerful Gordon's currently listed on Japanese auctions...I have 2, as do several other members possess them...
I have only seen ONE Talk 'n Action Gordon in 6 years of hard core collecting, and there is only a box to show for one online...I have NEVER seen a T'nA Henry, and the Snow Plow set is most elusive!!
That said, the top 3 rarest trains based on TRUE rarity are:
1.T'nA Henry
2. T'nA Gordon
3.D&D Snow a Plow set
