Ok, so just an heads up. The curved sections that I made the insulated track did not work. So, eaither I hit them too hard with the hammer, or they have sharper tie holders then the stright track. When making a layout, always, always, test stuff before putting it in permanently. Lucky, I am testing all peices before installing for continuity with a cheapo harbor freight multi meter. And I am not geat with multi meters, its easy to do. So, check your ceter rail vs the outside rails with the multi meter and you should get a 1. That means they are not conected. If you get a 0 they are conected and voltage will flow through them. My insulated rails, were reading 0 when trst vs each other. This meant there was a conection from the rail to the metal. So, its fixed now. But test all your track before laying it down. That will prevent problems later.
