i am having troble getting my mrc dcc system connected to the track i have the wires but i don't know what the best way to solder it to the track if anybody had any ideas on a good way to do that.
atlas sells teriminal railjoiners, which are basicly a railjoiner with a wire soldered to it already. just carefully bend the wire part down and drill a hole in between the rails, and feed the wire through. you can solder the connections to that wire.
