For those of us with children, or grand children around, that like to run trains at top speed, there is a quick an easy way to slow the train down.

Simply, program the decoder CVs to use a lower "max" voltage, thus limiting the speed. You'll need to change two CVs - CV05 (max voltage) and CV06 (midpoint voltage).

CV02 should remain unchanged from "normal speed" to "limited speed". Some people have an extra locomotive just for these situations and always leave them set for slower speeds.
