The UP was kind enough to set out a bad order Gunderson 53' articulated double stack in an out of the way location with easy back road access. So I took a hundred plus pictures of details.
Not sure what this thing does but my guess is it activated the brakes if the car tilts too much.
You can see the leaning car
So that's the way the bolster and coupler are in the real world
And that's what the articulation joint looks like
A Load guide that Lionel got right and Atlas got wrong. Whhaaaattt?
Is that wheel out of spec? This is the tilting car. I always wondered how brake cylinders were attached to freight trucks
Thanks again UP!
