X class (Ser. 2) by Austrains

Here, an ESU LokSound V4 Standard decoder with 23 mm speaker has been fitted to an Austrains model. In this example we've shown a few more steps in the installation process. Access to the chassis is relatively straightforward, the handrails being the only tricky bit on occasion. The body assembly is moved up off the chassis and walkway:



The next step is to remove the Austrains DC board as the decoder will be hardwired, including installation of LED lighting. A single 470 ohm resistor is spliced into the negative lead of each headlight wire from the decoder, in this case the white an yellow leads. Both headlights then run back to a common positive wire (blue).




An ESU 23 mm speaker is placed in the fuel tank, where the tank acts as an air tight enclosure over the back of the speaker, providing better base response. In this instance a specific type of polyfibre has been added to enhance the dynamic response of the speaker, and it proves to be very effective.
