Step 5: Setting the Momentum
The SoundCar decoder is designed to take into account any momentum you
have programmed into your locomotives in order to synchronize the rate of
certain sound effects with the train’s speed (such as wheel noise and braking
applications). If CVs 3 (Acceleration Rate) and 4 (Deceleration Rate) (or
CVs 23 [Consist Acceleration Rate] and 24 [Consist Deceleration Rate] if in
an active consist) are set to anything other than 0 in your locomotives, the
same value should be programmed into your SoundCar decoders to sync
the momentum to the locomotives. For more information, see “Consist Inertia
Control” in the “Consist Operations” section.
