Zinc rot hit me on my AtlasO WWII two bay hoppers. Atlas was kind enough to give me a discount on replacement frames for the cars but to swap them is a real pita. The joy of model train production from over seas

I will have to check the part number on mine.
Any way to prevent this?

Anyone know how to put larger pictures in the thread rather than the thumbnails? Like this?:  Easy peasy: just upload the pic to a photo or file sharing site, copy that file's URL, then just use the "Insert Image" button to paste the image's location into the message. A bit clunky, but at least you can see the image when you're done!

I had coal portal hoppers from MTH that started to fall off the track because of zinc rot of the trucks. 6 over a period of about 3 weeks kept collapsing. Two never had it but the other six are in a box waiting for repair. One day I'll get around to it.
Like someone said, ah! the joys of Chinese production!!!!

I’ve had to replace 2 sets of trucks on Atlas-O Wisconsin Southern cancer boxcars that were manufactured some time ago. At first, the wheels froze after significant binding. Then one day I removed the boxcars from the display shelf… and the trucks just crumbled.

Not sure if this works for everyone. But many years ago an old Model Railroader I met at a shooting match told me to soak overnight item which maybe suspected of getting Zinc Rot. He said he's done it for decades. I had some Atlas coal cars that I had heard of getting zinc rot so I did as he said, soak in Vinegar overnight. That was a long time ago and iems haven't shown any signs of Zinc Rot. He also said that High Humidity speeds up Zinc Rot one reason his basement had 2 De Humidifiers running 24/7.

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 really sucks!! It's post like this that prevents me from ever buy new from Lionel.

Unethical manufacturing processes in the Far East are responsible for this outrage, totally preventable in this day and age.
