RailKing SD-90 MAC Operating Manual
B. After entering Neutral, ProtoSounds® will immediately play an
air release sound followed approximately 2 seconds later by a Cab
Chatter Arrival Message. The arrival
message announces what yard the engine
has arrived in (the yard is described as
either Yard A or Yard B, alternating each
time FYS is enabled during the current
operating session. If the engine is turned
off for more than three seconds,
ProtoSounds® will automatically return
to the Yard A message the next time FYS
is enabled). Immediately following the arrival message, the sound of
freight car doors can be heard opening, followed by the sounds for
forklift engines. At this point various freight yard sounds can be
heard including forklift operation, engine sounds, reverse warning
horn beeps, and additional freight car door sounds.
Event 3: (Reverse) The operator now interrupts the transformer throttle
again to enter the next reverse unit phase; reverse. In an effort to enhance
realism, FYS has disabled the reverse phase so that it doesn’t power the
motors causing the engine to move backward. Upon entering reverse, FYS
confirms to the operator that it has entered
the reverse phase by immediately playing
a highlight sound best described as a
rumbling sound. You may have to go
through the entire FYS sequence several
times before you can clearly identify this
sound. After the rumbling highlight is
played, the freight yard sounds heard in
Event 2 continue to play randomly.
Event 4: (Neutral Before Forward) The operator now interrupts the
transformer throttle again to enter the next reverse unit phase, neutral before
forward. FYS confirms to the operator that
it has entered the neutral before forward
phase by emitting two quick air release
sounds. This is followed by a Cab Chatter
message that the engine in Yard A or B
(whichever yard designation was played in
Event 2) is preparing to depart the yard.
