Bachmann Class 55 Deltic Diesel DCC Sound

Example 1: Bachmann Deltic (version with factory lighting)

A beast of an engine, and very heavy model. However, not much space for speakers, so we've made use of the fuel tanks, adding a pair of YLR-302506 speakers down there.

NB we'd probably use IceCube25X18X06-1W speakers instead now, which sound much better!

Example 2: Older Bachmann Deltic (no factory lighting)

Kit: MX645R; IceCube28X18X10-2W; red flat-top LEDs; cab lights

This example is of an older Bachmann Deltic, before they added lighting. The approach is relatively similar though, utilising space in the fuel tank for a speaker. Speaker depth is all-important for the Deltic sound profile, to maximise bass response, so we create an aperture in the base of the fuel tank for a big 10mm dual IceCube to sit.

Example 2 Example 2

We remove the tank's metal weight - the model is still very heavy, so should retain good traction. The IceCube only needs half the fuel tank though, so we could cut the metal in half and retain half the weight there if we so desired.

Example 2 Example 2

We secure the speaker, flush with the floor, nice and tidy.

Example 2

Extra wire holes are drilled down for the speaker wires to pass through.

Example 2 Example 2

Tape covers the metal part of the speaker to avoid shorting with the motor when reassembled.

Example 2

Chassis reassembled, and decoder plugged in and connected to the speaker. Testing can be done at this point.

Example 2 Example 2

It is a fairly easy job to add red tail lights to this model - just drill out the lenses and glue in red flat-top LEDs, blacking them out internally once glued in place. One resistor per end to protect the LEDs. In addition, we put yellow SMDs for cab lights, controlled off the decoder's FA1 and FA2 (green and brown wires) outputs.
