This may be a simple question but I just needed some clarification on wiring a DC layout. As your layout expands do you need a more powerful DC controller or just more wires feeding out to the track? <br /> <br />To phrase it a little differently, does there come a point where the DC controller becomes underpowered for a long length of track? (Even with feeder wires every few feet) <br /> <br />I just can't seem to get my head around that.
