That really sucks!! It's post like this that prevents me from ever buy new from Lionel.
This set is 14 years old. Also this issue isn't limited to Lionel. That being said, I'm just happy it's operational again.

That is a seriously nice set and my favorite road name.

I haven't had alot of items with zinc rot just a few like the coal porters, Mth's original triplex boiler and a few other diecast trucks. It happens to all builders
Especially overseas.

Has anyone kept a list of items with potential issues? BTW this is common with 1:18 diecast automobiles. I've seen pictures of them still unopened in their window boxes that are disintegrating.

BTW: I guess I’ve been very lucky since I’ve not had the issue yet. I hope I never do.

I've had the issue with several Railking 19th century rolling stock trucks. I currently have 4 cars that I don't have trucks for because of this, and it's too expensive to buy new trucks!

—————— I think this is how it goes… 1. Post the thumbnail as you normally would under ‘Add Attachment’.
2. Click on the thumbnail, then copy the URL from the address bar up top. 3. Return to edit your post and click on the picture/URL icon, seventh from the right. 4. Enter the picture URL in that box, then remove the thumbnail pic from the post body. 5. Save the post and you should have a great big photo sitting there. Dave

Zinc which is used to galvanize iron to prevent corrosion, does so by creating a passivating layer (an oxide) to restrict oxygen from getting to the iron. In any case, zinc is more reactive than iron and would corrode more easily. The process of immersing zinc components in vinegar may have some merit and analogy to the fact that zinc will form a carbonate coating upon exposure to water and carbon dioxide in some circumstances. The acetic acid in vinegar may then play a role in forming a zinc acetate coating and therefore a passivating layer to oxygen. A practice to prevent underground iron pipe corrosion is to connect the pipe to a more reactive element like magnesium – the magnesium would preferentially corrode and preserve the iron. If a more reactive metal is used inContact with zinc, corrosion may be minimized. In the case of the zinc rot – which I presume is the formation of zinc oxide – it may be possible to reduce the oxidation by contacting the zinc with a more reactive metal like magnesium. I don’t know if this would be practical; certainly it would be costly. I can’t say for sure, because I don’t know the composition of the material used in the trucks, its distribution, or level of content. Alfred That’s very interesting, Alfred. I have a Williams 4-6-0 with disintegrated trucks that I cast some resin replacements for. Would the vinegar pickling create a barrier in any porous areas and prevent the reactions that cause the crumbling and distortions? Sometimes the distortion looks like it’s coming from the inside out. I understand the deformation is from poor quality control in the alloy production that allows impurities in the mix. Dave

Dave (firewood), I have not seen , in person, the effects of zinc rot. From what you describe, the effect may be internal. As a result of poor metallurgy or material characteristics. Oxygen diffusion might occur through micro-fissures to cause internal oxidation, since mechanical stress does not appear to be a prerequisite to initiate the effect. It is a complex problem. In any case, if Mg is the solution, then I am going to buy stock in magnesium mining. I am continuing to develop ZD-40 (Zinc Defense – formula 40), patent it, and make a fortune by selling it at York. Alfred
