Someone asked the question the other day about whether or not to close the loop of the DCC bus, and thus sending the signal by shortest path of resistance over the layout. For instance, the wire for rail 1 is on bus wire 1, and rail 2 is on bus wire 2, imagining the track makes a simple circle, you would connect both ends of bus wire 1 (to make a circle) and connect both ends of bus wire 2 (to make a second circle. Someone then replied something to the effect that this would potentially 'echo' the digital signal. Well... isn't that exactly what the rails do if you install them with no gaps? Don't the rails complete a full loop in the circle scenario, and thus, wouldn't you be essentially closing the same loop as the bus is powering? So, if you had a continuous loop of mainline, why wouldn't it be practical to close the loop of buswork (each end of wire 1 to wire 1, and wire 2 to wire 2) in order to do essentially the same thing that the track is doing? I think the 'path of least resistance' idea makes alot of sense, since logically, the track would be doing the exact same thing anyway. <br /> <br />
