I would imagine the insides will be much the same concept for swiveling as the Bemo one is, likely 3 Bogies connected with the 2 Body Parts tangental in the middle with flexible or sliding parts to disguise the joint. Likely this will be what the prototype is like, though getting that through R1 it will be interesting to look at the gap on the Outside of the curve. The inside gap on the Inside of the curve will be challenging as well on R1. But we must assume that Marklin/LGB have nailed it.
Both in the english and the german press, LGB has been pretty adamant this a scale model. I've read and seen enough that I'm convinced the engine will be the correct length - the width is still in question in some people's minds.
Thanks Keith! Just what I needed - to be reminded that I want the refurbed square headlights that KISS offered... that LGB is not.
