ISO: Trinity 5161 Hopper Prototype Drawings

[ednadolski]

Can anyone please point me at any drawings, detailed pics, and/or other kinds of dimensional info for the Trinity 5161 cuft. grain hopper?   I'm doing a bit of proto research so any kind of info would be helpful.

One of my priorities is to figure out the dimensions of the corner angles and other elements of the end cages.  I've looked thru the David Casdorph articles in the old MRG 2003 series, which are informative but regrettably do not have any actual drawings.

Thanks in advance,
Ed

Here is a diagram from BNSF's website for the 5161.

One idea is look at the models...I would think they're reasonably close?  (or maybe they're not and you're trying to fix them?)

Here's an HO undec: https://www.ebay.com/itm/Trinity-5161-cf-Covered-Hopper-12-Course-Undecorated-Athearn-Genesis-HO-G4290/283882114360?hash=item4218b14d38:g:L6kAAOSwo-5ePiIU    There are some N but figure easier to get dimensions off the larger scales.   There's a 4-pack of Atlas O in BNSF, but at $600 that dips into the research budget quite a bit.   

Anyway, I would actually be interested in detailed drawings/plans too.   Would love to get these in Z-scale.

Great, that's exactly what I had in mind!  Thanks!

Yes, the latter.  The Atlas O model is a good base, but it has a lot of inaccuracies and compromises, particularly around the bolsters and end cages.
