Just starting the wiring on my layout. The layout has four bus runs of 15 to 20 feet in a radial or star pattern originating from a terminal barrier strip that is connected to my command system with a single pair of wires. I want to break up the layout into four power subdistricts and use seperate circuit breakers for each subdistrict. Do the power subdistricts have to coincide with the bus runs or can they go across or straddle two areas powered by two seperate bus runs? Using NCE Powercab without a smart booster right now but will be adding a smart booster after a while.

I have installed a dozen blocks using current transducers (CT) to sense presence of an engine (or lighted car) in a block. I use DCC. The circuits were designed by Bill Hudson (see hudsontelcom.com). Some of my signal heads work fine. Some are showing a double indication, ie, the clear signal (green) stays lit. I can't figure out what's causing the problem even with Bill's guidance by emails. All the circuit boards work correctly if I install them in a block where a signal head works properly.

I have three questions regarding JMRI throttles..

Hi.

I am having trouble with Micro-Tsunami TSU 750 decoder that I installed in a DCC ready HO Bachmann 80 ton three truck shay locomotives.

I have yet to connect the speaker as I wanted to see if I had done it right first before modifying things to fit the speaker.

The loco moves forward and in reverse but very slowly and with much noise and the light don't come on.

So I put another locomotive on the track and it works fine. I took the tender apart again and rechecked my soldering work, it appears to be ok.
