Diesel and Electric engines have certain commonalities and are therefore described in the same chapter:
Diesel-electric propulsion systems have sound components (sound sequences) from both areas. On the
other hand, the separation of "Basic settings" and "Load dependence" (as with the steam engines in the
previous chapters) is not practical.

With this setting, the diesel motor’s reaction to the
load (defined by PWM and speed step).
NOTE : the sound of the diesel motor practically al-
ways depends on acceleration and speed.
Diesel-hydraulic loco - higher and lower PWM
and performance steps,
Diesel-electric loco - driving/idle loco with
switchgear - steps.
= 0: no influence Motor PWM according to speed
= 1 to 255: increasing to maximum influence
NOTE : It is recommended, first to perform the
automated test run with CV #302 = 75 first (see
chapter 5.2).
#154 Various special bits -
Bit 1 = 1: (DIESEL) Drive off immediately even if
playback of idle sound has not yet finished.
Bit 2 = 1: DIESEL, ELECTRO After short stops,
wait for idle sound before driving off.
Bit 4 = 1, bit 7 = 1: see STEAM.
#158
Bit 1
SW version 5.00 and
higher (only
diesel mechanical)
Various special bits
(mostly in connection
with functions defined
in various other CVs)
Bit 1 = 1: Diesel mechanical: RPM is not raised
when braking (see CV #364).
Bit 2 = 0: RailCom speed feedback (km/h)
feedback in “old” format (for
MX31ZL, RailCom ID 4)
= 1: RailCom speed feedback (km/h)
Normal feedback (RailCom ID 7)
Bit 3 = 1: “Looped” driving sounds (i.e. idle sound)
will be faded out when switching to a
different speed step in order to shorten
the sounds.
Bit 4 = 1: Steam chuff frequency increases slower
at high speed (non-proportional)
Bit 5 = 1: Braking (even by one speed step)
causes the motor and turbo charger
sound to pitch down one sound step
.
#344
Run time of
motor sounds
(Cooling fan, etc.)
after stops
0 - 255
=
0 - 25 sec
-
After the engine comes to a stop, some accesso-
ries are supposed to remain operating (e.g. cooling
fans) and automatically stop after the time defined
here, provided the engine didn’t start up again.
= 0: Will not run after stop
= 1 - 255: Runs for another 1 to 25 seconds.
#345
Switch key
to next sound
variation within a sound
collection
for different operating
modes of a locomotive
or
between the sounds of
a multi-system engine
1
– 28
Defines a function key (F1
– F28) which switches
between two sound types that is, between the se-
lected sound in CV #265 and the next one in the
list. For example:
- Switch between two modes of operation (light
train / heavy train) or
- Switch between electric and diesel propulsion of
a multi-system engine; typical case:
Sound project for RhB Gem.
#346
Conditions for switch-
ing between
collections, as per CV
#345
0, 1, 2 0
Bit 0 = 1: Switches also at stand-still,
Bit 1 = 1: Switches also while cruising (bits for
standstill and cruising possible at the same
time)
Bit 6 = 1: Transition sets in diesel projects, which
are played back when switching from one set to
another.
#835 Further switching keys 0 - 32
Extension to CV #345. Here the number of consec-
utive keys can be defined, which then switch to auf
Set2, Set3, Set4, …. .. Then first key is still defined
in CV #345.
#347
Switch key

and sound perfor-
mance
when driving solo
0 - 28
= 0: No key, no switch possible.
= 1 - 28: One of these function keys (F1
– F28) acts
as the switch-over key for driving a heavy train or a
single locomotive. Parameters are selected with
CV #348.
#348
Selection of
measures to be taken
when switching to
solo drive (with key se-
lected in CV #347)
0 - 31
When driving solo (function key as per CV #347 is
ON), …
Bit 0 = 1: ... Diesel sound (sound steps)
shall rise unlimitedly at acceleration
(otherwise limited by CV #389 dependent
of speed step).
Bit 1 = 1: ... acceleration and deceleration
times should be reduced according to
CV
#3 / #4 but consider the range of
reduction defined in CV #390.
Bit 2 = 1: ...driving at low-speed ranges with
stationary noise possible, whereby the
highest speed step with stationary noise
is defined in CV #391.
Bit 3 = 1: 2nd smoke fan and heater deactivated
with loco driving key (two-motor diesel
loco only drives with one).
2
nd
smoke fan and heating deactivated
on the higher output each if this key is
ON
Bit 4 = 1: Brake squeal is suppressed with
loco driving key.

in the ZSP flow diagram), actual changes in speed
