Whats the rarest Tomy/Plarail train you own?

@Mod Thana

If I may can I ask .. Did you get that blue Evolta Tram from an Online Auction site, Online store or a visit to Japan? (you don't have to answer, I understand)

The real one does not look like a re-wrap of the first one so I am assuming it is actually a second version. With a little research uncovered that this second one was built by High School students but I am unsure of what size dry cell batteries they used. The first Tram used 99 D Cells for power. This article states that the blue Tram used 600 batteries but failed to say what size. I guess I would have to assume that since the first Tram used 99 D Cells that this second version must have used C or AA since they used so many more. Anyone know?
