Even when you arent running the loco! My personal advice is keep the lenz decoder for your control and add one of the soundtraxx that does sound only, not motion. It is a little tricky to program an engine with 2 decoders, but easier than running after a runaway engine going about 200 scale MPH. <br />[/quote] <br /> <br />Joe: <br /> <br />I have full Soundtraxx decoders and I don't have the problem you describe. <br /> <br />The most common reason for that behavior is CV29 is set to recognize Analog DC operation. As a rule, I turn this feature OFF on all my decoders and the runaway loco problem has disappeared. Any time we have a runaway loco problem now days, I can always trace it back to a throttle issue. <br /> <br />To set CV29 to analog mode off (assuming it's on now) just subtract 4 from the current value in CV29. Or set bit 2 off, whichever you are more comfortable with. (Or use DecoderPro and just uncheck the analog mode box -- it doesn't get any easier than that!) <br /> <br />I highly recommend Soundtraxx sound decoders and find them to be very reliable. The quirky one of the lot is *actually* the DSX sound only decoder -- it will drive you nuts trying to program it since it seems like it at times wants to be the decoder attached to the motor too. <br /> <br />[/quote] <br /> <br />Thanks, I'll have to pass on that information as it is not my engine im mentioning, but you have quelled my fear of soundtraxx.
