I don't think I have ever seen micro mini Plakids before. Where are they from?

Hey Guys, I'm Planning On Making A Layout By Combining These Sets:

1. Plarail Bill And Ben Harbor Friends Set
   
2. Plarail Thomas And Spencer Racing Set
   
3. Motor Road And Rail Thomas Adventure Set
   
4. Motor Road And Rail Track Expansion Pack
   

Does anyone know what made this hard to find and very special Diesel 10 so rare and valuable?

Will the Thomas that comes with the yet to be released Plarail Boulder Mountain set have an entirely new facial expression? Looking up with a shocked, open mouth look? Or has it been used before? One picture makes him look like he is looking straight up and the other makes him look like he is looking up and to the right.

I just saw this in Jauce.
I have never seen this before.

A plarail truck that runs on Blue Track. Awesome

Been after a set of these for a long time. They rarely show up in the Auctions and when they do I am always out bid...maybe one day.  

Does anybody knows which set this coal hopper car comes from?

Tokyo Plarail Expo Exclusive 2019 SL ASO Boy

Does this mean the the Tokyo Expo has started?

This looks to be exactly like a previous release of this engine and tender. Exactly the same except this one has red side rods. The trailing coach is different but in my opinion not something to write home about.
