Hello All, hope all had a great Christmas. I want to know if anyone has or knows which sound decoder will work in this steam engine? Basically size wise.   God Bless Ya   Dave 

I have a Walthers HO scale locomotive with a factory installed sound decoder. It was purchased about 15 months ago and used a few times. I got it out of storage a week ago. It worked normally for about 10 feet and then I shut it down because someone arrived at the house. A couple of days later I powered it back up and it shorted out immediately. I tried other sections of the layout and it still indicated a short. Other DCC sound locos work fine on the layout.

Well I'm not sure where to start.  So I will start with the problems that I am having.  First off I am trying to set up a stand alone LocoNet using RR- CirKits LocoBuffer-USB which I have no idea if its even working.(any way to test this??)  Next I have a Tam Valley QuadLN_S that I am using for servo turnout control.  I think I have set things up correctly but I cant get a servo to work when I have added it the turnout table in JMRI.  I looked to see if JMRI had a forum and gave up on that.  So I am hoping someone here can give me a hand.  I have

Digitrax using PSX circuit breakers (CB).

During operating sessions, while several trains were running, sometimes all the CB's would start flashing on and off shutting down the entire layout until the short was corrected.

It took me awhile but I was, finally, able to recreate the problem.  I put an engine on each power block district that each CB was controlling and then put a quarter in each block until the problem occurred.  

I emailed Larry Meier at DCC specialties and he gave me a few things to try.
