Reply to "Gargraves track and outside rails"

One rail will do fine if you are just running loops. If you have several switches or multiple connected loops then you may want to ground both sides. Also having some sections of outer rail isolated can be used for trackside signal activation or some other device. I have done it both ways, but normally I do ground both outer rails and tie them together.
