My official "first plarail" and a question

Last week, I got a Cross Thomas in the mail from another user on the forums, that could be the JP version, or the UK version, I'm not sure. I have tons of US and UK Tomy items from my years of collecting, but no JP Plarail. I've been getting some in the mail recently, but I can't use them until Christmas (;3), so I don't really count them as mine yet. However that Cross Thomas may be my first official Plarail I can use. However, if it's not, I found this red engine at a street vendor today. I knows it's likely JP plarail, and it works, albeit with semi loose, fresh-looking, traction tires. Can anyone tell me more about it? Here's a pic of Thomas and the red engine.
