PRR S-2 Turbine Operating Instructions
whistle button. Interrupt the transformer throttle to enter the next directional
state (either forward or reverse).
(Note: the FYS will only play in the first
Neutral after it is armed. You cannot interrupt the power twice to enter
another direction and still have the FYS active.)
You can now trigger the
sounds to begin playing when you next enter Neutral.
TRIGGERING FREIGHT YARD SOUNDS
Once the FYS feature has been activated, it will be played the next time
the engine enters neutral. At this point, Proto-Sound® will take over
control of your engine, disabling the bell and whistle button. In addition,
Proto-Sound® reconfigures the way the reverse unit functions during the
operation of the FYS feature. This forces the engine to leave your freight
yard in the same direction as it arrived. The following operator controlled
“Events” control the FYS’s actions and sounds.
(Note: The direction states
shown assume the FYS is entered from forward. If entering the freight
yard in reverse, the direction states shown will be reversed.)
Event 1:
Interrupt the transformer throttle
to cycle the engine from forward into
neutral. If the throttle was at 14 volts or
higher, the squeaking brakes sound will
play. Once the engine is stopped, the
throttle must be turned on to keep it in the
neutral state.
Note: Failure to turn the
throttle back on within 3 seconds of
leaving forward will disable FYS and shutdown Proto-Sound®. The next
time power is turned on, the engine will be in the RESET position. See
page 18 for additional information on RESET.
If the bell was not turned
off after arming FYS, it is now turned off automatically. After entering
neutral, Proto-Sound will immediately play a whistle blast or an air release
sound, followed approximately 2 seconds later by a man whistling and a
freight car door sliding open. At this point, various freight yard sounds can
be heard, including loading and unloading operations, engine sounds,
yardman “slang,” and additional freight car door sounds.
Event 2:
Interrupt the transformer throttle again to cycle the engine from
neutral into reverse. In order to have the engine leave the yard in the same
direction it entered Proto-Sound® disables the motors in this reverse state to
prevent the engine from running backwards. FYS confirms reverse is
entered by playing a sound highlight best described as a rumbling sound.
