I'm sure many people have already solved this but I'm in the process of building my first big layout and only. Bought a new MTH P&W Dash 8. Due to its length keeps stalling on my atlas turnouts. Most of them have power on track to at least two ends. I was told I should put power to all track/switch ends. This seems like overkill, any simpler solutions for a guy who is not a full train techie?
