4.1.2. Diesel locomotive:
Start up of the engine
First a compressor starts, thereafter the main engine starts.
Standing noise
The Diesel engine runs in idle as the locomotive rests. A compressor may start or excessive air pressure may
be released depending on the programmed sounds.
Driving sound
The Diesel engine produces a sound depending on the speed of the locomotive.
Locomotive shut down
The Diesel engine is switched off and the sound of the engine running down is produced.
4.1.3. Electric locomotive:
Locomotive start up
If available the sound may start with the sound of the air valve. Thereafter the main switch is flipped and the
compressor starts. The sequence is completed by the sound of the starting cooling fan.
Standing noises
The standing noises consist of the sound of the cooling fan only.
Driving sound
While driving, the sound of the driving motor is produced, depending on the speed of the locomotive.
Locomotive shut down
First the cooling fan stops, the the vacuum pump starts. The sequence is completed with the main switch.
4.2.Additional sounds
4.2.1. Sound selection, number of loops (endless loop) and volume
Additional sounds may be triggered by F-keys e.g. operational sounds of the locomotive, whistle, bell,
generator, compressor, or station announcements. The allocation of these sounds is accomplished by CV
settings (configuration variables).
The whistle, sound #1, is assigned to CVs 131, 151 and 201. The whistle with echo, sound #2, is assigned to
CVs 132, 152 and 202, and so on.
The first CV contains the number of the F-key, which triggers the sound, in this case “1“, which stands for F-key
1.
CV151 contains the number of loops (repetitions) of the sound. The sound will be repeated once if the CV
contains a “1“, twice if the CV contains a “2“, and so on.
The sound may be repeated up to 15 times. In case “16“ is set in CV 151, the sound is repeated endlessly. This
means, the F-key switches the sound on and it will stop only after the F-key is switched off again.
The volume of each sound may be programmed separately in steps of four:
3 = max. volume
2 = ¾
1 = ½
0 = ¼
This value is set in CV201 for sound #1, in CV202 for sound #2, in CV203 for sound #3, etc.
