Interesting, for the first 5 times around 
... Are these sets that you bought AC?
I am curious as the first video shows a Trackmaster II but it seems to be at a Japanese Toy Show or Plarail Expo. Strange as I didn't think they were sold retail in Japan...at least if you go by how expensive the Trackmaster II trains are going for in the Japan Auctions. Of course the second video is Plarail for sure.
