I'm using the Märklin track and also their power connection. On my portable layout I have the cables dangling, not very clean. Does anyone have a cleaner connection? I'm thinking maybe a mono headphone jack?
Any 2-position connector will work well. I have used Molex connectors, headphone jacks and power connector jacks. You can hide the connector in a building or other scenery, or you can mount it to the layout fascia...if you have one.
