I just watched a Train Cruise that featured the Nishikigawa line and its fleet of multicolored NT3000 DMUs. I see Max Model makes a kit for the NT3000 and several decal sets: http://www.1999.co.jp/eng/10099256 This is an unpowered model. Has anyone ever seen it, and does anyone have ideas for powering one? I'm thinking a BullAnt drive would be a good option (which would also allow 12mm or 13mm), but I'm sure there must be an indigenous drivetrain available.
