Soundchipping an HO Atlas SD35

[Jon Grant 4472]

My latest project changes era again, back to the 1990s, after spending the last couple of months in 1930s Chicago and 1940s Pennsylvania.

I hope to fit a Quantum Revolution soundchip into an Atlas SD35 and then detail the loco to show three different owners at once - Atlantic Coast Line, Seaboard Coast Line and CSX, with lots of patchwork evident.

The first job is to make room for the speaker and soundboard, including the capacitor by cutting away parts of the loco weight. I also removed the dual-mode DCC decoder that came with the loco.






The next job is to make a seat for the speaker above the rear truck and fit the rear light.

Ps. Those of you who have followed the progress of Sweethome Alabama may have noticed that the hill in the background has been somewhat de-forested - the trees went to Sweethome Chicago last month
