“I have an Athearn RTR SD40 which won’t slow down. I’ve tried speed table programming without success. It has a soundtraxx Tsunami decoder. Anyone else had this happen?”

Call soundtraxx. They are very helpful in selecting the proper CV setting.
Usually cv03 is the program setting for acceleration and cv04 is deceleration.
Tom, if you haven’t already, check the Motor Starting Value cv02. Lower setting = slower start. may be set too high.
