Engine Sounds - M.T.H. HO 4-6-6-4 Challenger Engineer's Manual

Engine Sounds

F25 – Engine Sounds
You can turn the Engine Sounds On/Off by pressing the F25 button. Pressing it once
(enabling F25) will cause the Engine Sounds to shut off. TheWhistle/Horn and Bell
sounds will still be active, however. To turn the engine sounds back on press the F25
button again (disable F25).
Additional F Functions
F14-F16 – Idle Sequence
Pressing F14, F15, or F16 twice (toggling on then off) will trigger an Idle Sequence if the
engine is not moving. These vary from engine to engine and may include things like
checking the coal load, checking the water level, using the Alemite grease gun on the
drivers, etc. When triggered, these will run through the sequence that varies in duration.
F17 – Extended Start-Up
If your engine is shut down or you've just applied DCC power pressing F17 twice
(toggling it on then off) will start the Extended Start-Up sounds. This is very similar to F3
except you will hear the crew talking back and forth about getting the engine ready to run.
F18 – Extended Shut-Down.
If your engine is already up and running you can play the Extended Shut Down sounds
by pressing F18 twice (toggling on then off). The Extended Shut Down is very similar to
F3 in that the engine will ultimately shut down, but in the case of Extended Shut Down
you will hear the crew talking back and forth about how the engine ran, time schedules,
etc.
NOTE – The engine must be sitting still in order to trigger F-Functions F14
through F18
F19 – Labor Chuff
To force the Labor Chuff sound in a steam engine, press the F19 button once (enable
F19). As long as F19 is enabled the engine will play its Labor Chuff sounds. To set the
sound back to Normal Chuff press the F19 button again (disable F19).
F20 – Drift Chuff
To force the Drift Chuff sound in a steam engine, press the F20 button once (enable
F20). As long as F20 is enabled the engine will play its Drift Chuff sounds. To set the
sound back to Normal Chuff press the F20 button again (disable F20).
F21 – One Shot Doppler
You can set your MTH PS 3-equipped engine to simulate the actual Doppler Effect sound
a real engine makes as it passes you. To do this, press the F21 button once (enable F21)
and then listen as the engine makes that pitch shift that mimics the Doppler Effect
perfectly. Press the F21 button again (disable F21) to shut off the Doppler Effect. With a
little practice in timing and speed you can make this happen right in front of you.
