RailKing PCC Street Car Operating Manual
required to synchronize the playing of the brake sounds with the movement
of the car. It is not uncommon for the car to stop before the brake sound is
completed. Operators will find that by coordinating the movement of the
throttle setting from 8 volts to off
will allow the car to maintain its
movement while the brake sounds
play.
Note: The brake sounds will
not be heard if the transformer
throttle is not set above 14 volts
and/or not reduced below 8 volts.
TIPS ON USING THE SQUEAKING BRAKE FEATURE
Because the squeaking brake feature always plays for approximately 3 seconds, it is
possible that the brake sounds will play longer or shorter than what visually seems
prototypical. You will find that by practicing with the brake feature, you can
determine how quickly to throttle down and what speeds and voltage settings
give you the most prototypical braking effect.
Typical users will find the feature to be a very realistic way to simulate the
sound of a car slowing down for curves, crossings or coming to a stop at a
station, side track or switch yard. As mentioned above, you will find that
initially your car may continue to play the brake sounds once it comes to a
stop or that the sounds stop prematurely before the car comes to a complete
halt. For example, if you simply run the car and turn the throttle off quickly,
the brake sounds will likely continue playing even though the car has come to
a complete stop. This annoying effect can be eliminated by simply practicing
with the brake feature. In no time, you will quickly learn how to “feather" the
throttle to keep the car moving while the brake sounds play and then turning
the throttle off just as the sounds stop.
The ProtoSound® squeaking brake feature also has the ability to simulate the
squeal of wheel flanges when your car enters a curve at high speeds. The
same brake squeaking sound plays, but you don’t need to reduce the
transformer throttle to activate the squeaking sounds. To play the squeaking
sounds as wheel flange sounds, you can trigger the brake feature with the
whistle button on the transformer. As your engine enters a curve (or anywhere
on the layout) quickly “flick" your transformer whistle button about half way.
This “flicking" action causes the transformer to release a short DC signal that
ProtoSounds® reads as an indicator to activate the brake sounds. The car
won’t slow down even though the sounds play. This simulates the wheel
flange squeal of a train traveling through a turn too quickly.
Note: Consistent activation of the wheel flange squeaking is determined by the
condition of your transformer’s whistle button rectifier disc. Older rectifier
discs may not release a clear and strong enough DC signal required by
ProtoSounds® computer to play the wheel flange squealing.
