This question has probably already been answered, but my only excuse for asking it is I feel lazy today. Does anyone make a electronic speed censor that would work in N scale with a digitrax dcc system? I was watching my layout the other night and had one of those wondering thoughts go through my head, what speed is that train running. I quess the real reason for one is, the question I have, am I being to critical of how well my engines are running.
