Walther Mainline sound Issue
Posted by hjQi on Saturday, September 24, 2022 2:23 PM

Hi,

I bought two Wlather Mainline SD70ACe with sound. The sound is ok iand the loco runs ok in general. But at some random locations on the track, the sound suddenly becomes a constant horn sound, and I lose the control of the loco from my throttle. The loco just runs at constant speed with a constant horn sound. Walther Mainline uses ESU sound decoders but I could not find any information regarding this problem. Does anyone have similar problem and know how to solve it?

I will asume you are running on DCC. If so a short will cause that when a decoder only part way shuts down but reboots mid stream.

Try turning off the DC enable setting in CV29. That can quite often cause strange happenings when running in DCC only.

Hi there. Is it one or both locos that do that? If only one, try a reset. If both have similar behaviors, I would clean the track and check the track.

Hi all,

Thanks for inputs. Both locos have the same problem. I contacted vendor and they told me that this batch of Walther Mainline seemed to have this problem in DCC. So I returned the locos.
