Odds are, anyone will experience zinc pest at some point especially if they have a lot of equipment. However, it's not totally luck-of-the-draw. You shouldn't find one random part affected on one random locomotive model, rather, it would generally be a whole batch of a specific part that's affected. For instance, these are just a few well-documented cases:
- Acela locomotive wheel journals
- JLC Allegheny front steam pipes and rear water hatch
- Atlas O Master Line 40' PS-1 boxcar ladders and grab irons from the early/mid 2000's
- JLC GG1 truck frames
Now, if you have one of these or other affected models, whether your particular piece will have the issue is luck-of-the-draw. But I would say you're extraordinarily unlikely to have the only known case of zinc pest on a particular model. For this reason, I think documenting cases of zinc pest is well worthwhile, both to raise awareness and to provide the opportunity for folks to share remedies or seek out solutions such as 3D printing or what not.
