Steve and I were talking about my railroad and I had mentioned that I had just refurbished enough brass track to complete my inner loop. I didn’t want to use any of the new box of Aristo aluminum flex track because another member in our club has had sections of his track twist out of gauge. That’s when Steve mentioned his problem. However the other club members layout is inside with fairly good climate control.
The aluminum rail problem has to be something in the manufacturing process that was used in China with the Aristo Craft product. I also have Micro Engineering aluminum rail in code 332 that I got from Bruce at SwitchCrafters and have no problems with it and its all in Aristo Craft USA ties. I guess only time will tell.
