I recently perchased Bettendorf trucks from Kadee. Kadee #500. I installed them on two athearns 40foot XM boxcars. I was pushing a string of cars through a curved switch when sparks crackled and my dcc shut down. I discovered that my new Kadee trucks rode up and shorted the switch. By experimenting I discovered that both boxcars with Kadees were doing this and no other car did. I installed them properly and I just can't figure out what's happening. Does anyone have an idea? I don't want to give up on these trucks if I don't have to.
