Well I Got my Birthday present (form me to me), an Aristo C16 and a USAT Docksider. Love them both, But with the C16 what Is the Brass bushing in the bag with the bell. And with the Docksider the red and black wire with a white connector, I know it plugs in to the board with the switches but what is it for? No word in the Destructions on what there for. As I'm writing this I not sure this goes here It is more for a "General Questions" forum. But as we don't have one on this site (yet) this will have to do for now. And I got an Aristo GP40 to, Nice Loco. I haven't had time yet to fully run them, more latter. Thank you all for the help.
