When planning a diesel installation the same rules apply. In general you
want to draw heat away from the decoder by mounting the flat side against a
metal chassis or weight, or providing additional airflow if possible. This may
not always be an option, so don’t mount the decoder above the motor which
generates it’s own heat and will cause the natural tendency of the decoder to
get warm during operation to be accelerated.
Figure 4 - Typical Diesel Sound Installation
Figure 4 shows a typical Tsunami installation for a diesel locomotive. In this
instance, the speaker is mounted in the fuel tank, with the module itself under
the fan grills. If the fan grills are open, some airflow can be created by drilling
some small holes in the bottom of the frame without compromising the sound
quality since the speaker is isolated in the fuel tank (a natural baffle!). If the
chassis is metal, the flat side of the decoder can be mounted against it to
help dissipate some heat. Like the steam installation on the previous page,
the decoder is not mounted near the motor or lamps.
