Limit top speed
Many folks stop at this point when adjusting their decoders. I
press on and limit the top speed.
Sixty MPH is 88 feet per second, or roughly the length of a
road switcher per second. So, if your loco moves past a fixed
point in one second, it is doing about 60 SMPH. If it takes two
seconds, it is going 30 SMPH. All but the largest layouts with
long mainline runs would benefit from speed limiting in the
30 to 40 MPH range, in my opinion. This means that the loco
will take about 1-1/2 to 2 seconds to pass a fixed point with
the throttle wide open.
The side benefit of limiting top speed is that the entire throt-
tle range controls the loco from creeping to maximum. It is so
