Overall Configuration

Fit a Soundtraxx DSD-090 into the box car along with some caps acting as an electrical flywheel.  Use a modified mini oval speaker installed in the tender of the loco.  This arrangement allows us to produce the sound as close as possible as to where the should should really originate from.  There will also be some room in the tender for a Digitrax RX chip.  

Above is a shot of the Mikado loco and boxcar with the temporary (but running) placement of the components.

Box Car Modifications

A 40 or 50 ft Micro-Trains boxcar will be modified to fit a Soundtraxx DSD-090 along with some caps acting as an electrical flywheel.  The power will be routed in from the original loco pickups. The motor control, sound, and headlight wires will be routed out from the box car.

Cut The Floor:

I milled this out to the approximate size of the DSD chip.

Test Fit:

Here's a test fit of the chip.
