Blue Plastic Tracks

Hi all, been awhile since I last posted here... got a few things, done a few things, yada yada, anyways, I've come across something which, from my brief look, I can find nothing about, and I'm wondering if anyone happens to have any information on the item in question or whether it is likely to be a custom, any information would be useful!

The Tidmouth recolor of Ffarquhar station is from the 2002 set きかんしゃトーマス はじめてのプラレールセット (Thomas the Tank Engine First Plarail Set), which comes in a bucket

Thanks Duck

This brings up an interesting question....

How many variants of this stations mould might there be? 4, 5, 6???
