A dual mode tram train that works both street tramways and heavy rail: two lofted sections on three bogies joined by concertina bellows, a 0.66 m floor line, wrap-around screens at both cab ends, four double doors a side, automatic couplers at modern coupler height, a single arm pantograph and collector shoegear on the leading bogie. Wheel flanges rest on y=0 so the rail plane sits at y=0.03; place the vehicle at y=0.57 over a track module to stand it on the railhead. Automatic coupler ports sit at each end at y=1.07. Bounding size 3.06 x 5.71 x 19.86 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: door-r1-a, door-r1-b, door-r2-a, door-r2-b, door-r3-a, door-r3-b, door-r4-a, door-r4-b, door-l1-a, door-l1-b and 21 more. Rigid node-transform clips: open, close and wheel-roll. No skinning. No collision or navigation data.
