Re: dimensional standard?

Thank you, Jack, appreciated.  One of the things that happens over time is you forget all the references you have to work with, and I do have this one.  Thanks for pointing it out.

Attached is page 2 from Gene Green extensive article on Air Brakes. The closest that I can get from the air hose brackets to the Kadee #158 scale head couplers is 16”.

I’ve always eyeballed the offset from the car centerline for the air hose brackets.  It’s usually been known to not be accurate anyway, since the coupler pocket’s too wide to allow it to be properly located.


But now that Kadee 262 Narrow Whisker pockets allow us to get a lot closer to reality, I’m moved to ask if there was (is?) an AAR standard dimension.  What can the members of this list tell me?
