"The only N scale set Bachmann makes with an F7 is the Super Chief set, however the locomotive included in that set does not have a DCC decoder."
Looks like this is the one I have.  Set it on a DCC track this morning and it BUZZED.

Thanks for all the replies I rec'd. Great help here for what little info was in my first post.

Well.........
Sorry about not providing the scale.
It is an N scale engine.
The board shows:      N637X
                              +PCB02A
It seems like the other road names start with the 63, but the next three numbers are different.
This particular engine evidently sold as a set with an engine, two cars, and a caboose.
I have found single engines on eBay where the listings use the 63775 number with an ATSF shell.
Any more of my questions will provide better descriptions!

Thanks!
It is not a sound decoder.
I'll see if I can find anything on a Lenz site.

Can anyone tell me what brand of decoder is in the 63775 F7A?
And maybe where to find instruction for the decoder?
Thanks.
