Weaver 50' flat cars w/swiveling homemade pipe load.
That's interesting!
Can you explain briefly what happens in curves? Is there some minimum diameter of track it can navigate (I suspect it's something like at least O54 or O72?).
Is it truly just a pivot or swivel on just the center point of each mount, or do the pipe holder pieces slide (side to side) along the wood supports they rest on? If so, is there some sort of mechanism in there to re-center them once on straight track again?
Maybe I am over thinking it. I guess it looks like it could be similar to a Schnabel car, which I'm pretty sure is is just a pivot point (that happens to have three trucks under it) under both ends (at least for our models - I don't know if the prototype is different). Of course the Schnabel doesn't have a coupler in the middle holding the ends, just the structure of the transformer and girders holding it mounted to each set of trucks at each end.
Sorry for the long question... Geometric issues sometimes fascinate me a little too much.
