You’re not a man of many words, so we need a little more typing, ……if the issue is constant derailing, you need to look at the tender trucks, and make sure they pivot properly, all the wheels spin, & are not bent, or if this model has chains to the trucks, make sure the chains are not tangled up in the trucks, and preventing the truck to pivot properly,……also, there is a 3/2 rail version out in the wild as well, does your model have scale flanges?….can you provide us an item # on the box, or a picture of your engine?…..
