Plug In Decoder For Athearn CF7?

[FCIN]

If you ever wanted to add sound, the big CF7 cab will accept a 1" speaker. Take some sheet styrene, cut it in a square which will fit horizontally in the cab, cut a 1" circle in that, and mount the speaker facing down. The upper cab will act as a speaker box.

Hey Gary! Thanks for that tip! As I mentioned, I really haven't taken the shell off one of these to see what the prospects for adding sound were, but that's a darn good idea! I would prefer to go with sound, so I'll look into that.

Both of the Athearn CF7's that I have are "DCC Ready" designed to accept a plug in decoder - at least that's what the box and the instruction sheet that came with them says...
