i need handrail stanchions for my intermountain gevo locomotives as the intermountain handrails are way to brittle. what are my options or is there any? what i would really like is the smokey valley brass stanchions for the ac4400cw but you cant find them anywhere. i drilled out the intermountain stanchions and used brass wire but the stanchions are so brittle and you cant get a steady supply from intermountain. can someone advise me on what to do?

Last time I bought some SV railings I had to go direct.

The only other option for ES44 handrails is Athearn. I don't think the AC4400 stanchions will be correct for the ES44, I think the design changed.
Also there will be no way to add the second lower rail to the SV parts.
I placed an order for SD60 stanchion over a year ago and have not heard back on paying for them or completion time.

yore probably right about the athearn handrails. i wonder if they could be drilled out for brass wire? we really need someone to make brass handrail stanchions as i dont really like the wavy plastic handrails. this hobby is getting very frustrating as we have lost so many good parts. i often wonder why smokey valley doesnt try to sell their tooling to someone that is willing to produce the parts, whats the value in holding onto tooling and not producing parts?

what about using the intermountain stanchions as masters and casting them in resin? would that work? anyone

The only problem I see when replicating existing parts is the loss of scale dimensions. Most master patterns are made 10-15% oversized to account for shrinkage in the casting process. If you can live with the loss, I would say give it a try.

it wouldnt be much loss though, would they be strong enough? anything would probably be stronger than the intermountain stanchions, the are beyond brittle. it is really too bad that smokey valley is not in business anymore, if they no longer want to produce parts why dont they sell it to someone else? there are no other options for brass handrail stanchions.

Depending on the casting medium, my guess is they would not be as strong as the original. My option in the past is to cut the railing off and drill the stanchions. It's tedious but the phosphor bronze wire looks better than the plastic, and once glued in place makes the effort worth while.

i did drill them all out and used brass wire, but i broke one of the stanchions on the right rear batterybox and they are different than the other stanchions. i have extra stanchions that go along the rest of the walkway but the side mount ones on the batterybox are shorter height.

The earlier ES handrails were the same as AC/-9. I’ve noticed from our newer classes of ES44AC that they use channel uprights. Near the top, the sides are cut at a 45 degree angle, and the back is bent to match the angle. U bolts actually attach the rails to the uprights.
