This thread is dedicated to building a list of Zinc Pest models. I was worried to see JR500's original post of his 300 Shinkansen series disintegrating, and while searching the Japanese internet, I found a disturbing enough number of cases that I decided to make a list. Zink pest, for those who do not know, is a corrosion of zink especially when it has been made with lead impurities. High humidity accelerates this corrosion a lot, leading to cracking, swelling, and disintegration of model trains. See here for more info: https://en.wikipedia.org/wiki/Zinc_pest The list can be found here (google sheets) Abandon all hope and despair all ye who enter. If you have an affected model and it is not in the list, please post about it, and I will add it in the list. Preferably with pictures if possible. You might be thinking, what can be done about this issue? The only real solution is by replacing the damaged part. Micro Ace provides repairs for those that have a receipt (and sometimes those who don't), and sometimes they sell replacement motor cars. Some on Yahoo Auctions have already had new parts that are unaffected. And that you own a train that is on this list, it does not necessarily mean yours is doomed to crumble into dust. But I would keep a closer eye on it. Current Count: 38 Models Last Update: May 23, 2023

Amazing... I got a real shock while I was casually inspecting my Shinkansens on display in my cabinet... It's amazing, the chassis has cracked! It's not like hot or anything in the cabinet, and it certainly is NOT exposed to any direct sunlight at all, in fact, not even near any sunlight... I wondered how the motor has cracked to such a state... The older trains is have like the 100 series or the E1 are fine, but this one... strange. Now I need to get another motor chassis for it... though it still runs...
