I need some help. I am starting my first big layout. I dont have dcc, but i have a Rivarossi Big Boy with sound and am wondering if there is an analog system that will work with Rivarossi locomotives with sound. Its going to be a decent sized wrap around layout, I only plan on running 2 trains on the main lines and maybe one or two switchers at a time. Sound is a must but I dont really want to go threw with upgrading and going threw each locomotive to make it dcc. I have no experience with dcc and am not technologically inclined. So any help or recommendations anyone can give me will help, and thank you for your time.
