What's is this set?

I hope this helps (I teach Japanese foreign language at my hs). It basically translates to "let's connect a lot blue train set". According to the guy in the video, it's from 2002.

I have a bunch of Plarail stuff and I go to Japan once a year and I love going to the stores but it's really endless. There is just so much stuff to buy. I've really cut down. The retail stores have all the stuff you can buy online (of course you save a bunch on shipping!) but finding rarer older stuff can be harder.
