Hi all
I have been reading with interest on another forum the topic of whether of not the power bus (which also carries the DCC data signals) should/can be wired under the layout as a ring or radial circuit. Searching the internet I can't find any reference to ring circuits being used anywhere, as they all refer to radial power buses.

Will any short circuit currents be better and fast returning via a ring or a radial bus
Will the data on the power bus be best served by a radial or ring circuit?

So, is a DCC ring bus advisable or is it to be the radial or perhaps it just doesn't matter?

Use a 1 watt 150 ohm resistor in series with a 0.1mfd ceramic or "monolithic" capacitor. Neither is polarity conscious. wattage of the resistor isn't critical - anything 1 watt upwards will be fine if 1 watt not available locally. Cost of these parts will be less than 50p

wiring is bus wire 1 > resistor > capacitor > bus wire two.

No need to change values at all withing the normal 11~18volt range of DCC bus voltages.

Hi Richard,reference to the dcc bus radial wiring due you add stubbers to both ends or one end,thanking you Mike.
