Ok, I've got most of my switch voltage poblems worked out. When I'm running the train over the main line and the normal speed it seem to run ok over the switches. When I through the switch if I don't slow way down the engine will derail. I'm running a K-line Allegheny with Lionel 072 O gauge switches. Is slowing down the SOP? Being new to this I'm still learning. Or do these switches suck? They do seem kinda sloppy when the wheels run over them. The rails are good with no visible wear.
