voltage on the motor leads to exceed the NMRA standards for
DCC voltage. This may damage your decoder.
Okay, so some momentum is good.
If you are using a sound decoder, you may want more momen-
tum set than with a nonsound decoder. Why? The motor in a
prototype loco won’t respond immediately to throttle input. It
takes some time for spooling up or down. The sound decoder
manufacturers generally create this transition in sound over
time. If you have no momentum set in the decoder and you
turn the knob from 20 to 40 miles an hour, the loco (and train)
may respond instantaneously, while the motor is still making
“20 MPH” sounds.
Okay, so, with sound, more momentum is better.
