YouChoos Resouces
Hornby OO GWR Star Class 4000

Example 1 - Easy Install

Kit: MX649R; IceCube18X13X06-1W

Excellent model again from Hornby, the Star has all the DCC fixtures in the tender.

We'll start with the easy approach, which is to use a small sound decoder (MX649R), plugged into the 8pin socket, and a low-profile IceCube speaker - no modifications required to the model at all.

The MX649 fits snuggly along the base between the plastic runners, with IceCube speaker on top.

If you didn't mind a little cutting of the plastic above, a higher-profile single IceCube would go in without too much work - 8mm or 8mm would give a marked improvement over the 6mm version pictured here.

Example 2 - better decoder, speaker, and big stay-alive

Kit: MX645; IceCube28X18X08-2W; SuperCap17000uF

A better result can be achieved by using bigger kit, but this of course requires some changes - the decoder needs to be hard-wired in order to fit the SuperCap at the rear, and the plastic under the coal load needs more shopping to get the MX645 in, and a really decent dual IceCube 28X18X08-2W speaker.

We've de-cloaked the MX645, removed unnecessary lighting wires, and re-covered it in Kapton tape. We also had to shave a little off the plastic turrets for the tender body screw fixings so that the decoder can slide in between them.

The metal weight has been cut a little to allow the wires to feed through and up, and the dual IceCube speaker is positions centrally, facing up out of a new rectangular hole under the coal load.

Once all is tested, we can rebuild a new coal load... in this case we used part of the original moulding, but added BlackTack toward the front, so the overall load sits a little higher. Finally, this load is carefully covered with UHU glue and crushed coal added.
