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. 3.
For multiple heading purposes, only one of the two Proto-Couplers will
function at any one time. Use the coupler direction switch as shown in Fig.
1 on page 3 to select either the front or rear coupler. Simply slide the
switch toward the direction of the coupler you want to make active.
NEUTRAL-ACTIVATED CAB CHATTER SOUNDS
Whenever your diesel locomotive is parked in Neutral randomly played
“Cab Chatter” sound effects will occur every 2 to 30 seconds. There are a
total of four of these Cab Chatter sequences that capture authentic radio
transmissions between dispatcher and engineer. They are designed to play
at random intervals to eliminate repetitive and boring sequences though
there is no guarantee that you won’t hear the same message repeated two or
more times..
SQUEAKING BRAKE SOUNDS
Proto-Sound® 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
sound itself is a stored recording
on the Proto-Sound® software
chip and will always play the
same brake sound for the same
three second length each time the
