Takara TOMY Plarail knockoffs (Thomas and non-Thomas related)

My friend EqualSeaso told me about these exports of Plarail. Well, for me it's looks the engines seems to have new original moulds and they can run on TOMY/Trackmaster track. Some of these engines has features like lights, smoke & sounds. (take note the soundchip is not the generic steam train sounds heard in many knock-offs)
This is very impressive compared to other china exports where they are very ugly and low quality like Southward Toys or Dumica.

Here are some photos of this series of train sets.
   
   
   
   
   
   
   

And here's a comparison of scale with a normal TOMY Thomas.
