Enhanced Neutral Steam Sounds; Squeaking Brake Sounds - Rail King Camelback 4-6-0 Operating Instructions Manual

When the knuckle fires open you will hear the buzzing of the coil
energizing and the sound of the air lines coming apart. It can best be
described as a CHA-CHUSHHH sound. The coupler doesn't have to be
fired in NEUTRAL. Once the
coupler is armed it can be fired
in Forward, Neutral or Reverse.
However, you may find that the
coupler doesn't open when
firing the coupler at high
speeds. Reduce the voltage
setting on your transformer if
this occurs and run your engine
at a slower speed before firing
the coupler. If the coupler
continues to open erratically, try
lubricating the knuckle with
light oil as indicated in Fig. 5.

ENHANCED NEUTRAL STEAM SOUNDS

The enhanced Neutral Sounds can be automatically heard whenever the
engine is in neutral. The sounds, which include Steam Pop-Off, Steam
Blow-Down, and Steam Injector sounds occur every 2 to 30 seconds. Each
of the three sequences will play at random intervals to eliminate repetitive
and boring sequences. While the sounds are selected to play randomly by
the microprocessor, there is no guarantee that you won't hear the same
sound repeated two or more times.

SQUEAKING BRAKE SOUNDS

ProtoSound® equipped engines feature the ability to play the sound of
squeaking brakes whenever your engine slows in speed. There are two
settings for activating the squeaking brake sounds. The default setting
allows the brake sounds to play while the engine is in forward or reverse
and the transformer throttle is lowered from a high setting to a low setting
(14 volts to 8 volts or less). The
other setting requires that a bell
button be used to "arm" the
brake feature and is explained in
more detail in the "Activating
Passenger Sounds" section found
