Questions about plastic rail from a newbie

Plarail makes real trains and THomas trains, and they run on blue track which is only available in Japan. Trackmaster is Thomas only, and it's available anywhere besides Japan

I disagree with you, they sell the blue track all over the world under the Tomy brand, I bought the hyper city stater set from a shop in England, so it's not Japan exclusive, although you don't get the full catalogue range, wheras in Japan it's a big thing and there are a huge number of home market specials,

Toy R Us in Canada still sell Tomy trains and blue plastic tracks but not a lot of variety.
