Kit: MX648R; IceCube18X13X13-1W
With the 8 pin DCC socket removed, there is actually quite a bit of space in the bunker.
Our customer has added DCC Concepts lamps to their model too...
Cab roof off, and in go the crew, and the firebox light...
Room for the MX648 and 13mm Ice18X13 to tuck up in the bunker. If you wanted, there is even room for a small stay alive, though
there isn't one fitted here... probably LifeLink with 3x or 4x 470uF Tantalums would go in without much extra effort.
