Hey Martijn,
Unfortunately we don't have much rolling stock in common, so I can't put in a request. I just wanted to let you know that I'm green with envy that you're the proud owner of the Tomix 0-2000 Sanyo Shinkansen ... and the 20th Century Memorial Set too ... lucky, lucky, lucky you!!!
Cheers

No need for envy really... I got lucky on the 20th century memorial set actually. I first noticed it (and the 100 series last run set) up at newhallstation for a silly price. I still tried to order it there though, but turned out that even though they listed they had one in stock, they didn't. About a week later, the guy who runs Japan Model Railways in Germany sent me an email that he got both the 0 series 20th century set and the 100 series last run set from a private collector who wanted to get rid of them. Needless to say, I bought them both ;)
They look great, but they're old tooling. The motors are pretty noisy, and the shell is pretty flimsy at certain parts.
As for the 0-2000, I've been having some issues with the power conducting couplers they've used. Sometimes it seems they're not aligned well, which means coupling certain cars is problematic. Once you get them coupled up, they're so tight, that the imitation diaphragm things basically just bind the entire train. I have the same problem with other Tomix trains using the power conducting couplers, but not as bad as on the 0 series.. Haven't checked if there's an easy fix for that yet though.
