NC Traction/NCNG Museum/facts straight

Finally getting the facts straightened out before I take care of both places for the Guidebook (which I haven't worked on for over a month, time issues); unfortunately, I'm missing a lot of saved notes/correspondences:
Nevada County Traction Co-
Running the 2' line with the Plymouth; short 3' (or dual-gauged) section with the Argent engine; but hasn't operated in some time I understand. Can anybody confirm the status of the 3' steam operation here?
Nevada County Narrow Gauge-
New site; displays only; eventual planned yard demonstrations on a short yard track using the Wilmunder 0-4-0T (ex-Sac.Brick). A&W/Wilmunder (Ex-Richardson Lmbr. Co) Heisler there as well; to be used?
I've finally gotten around to dealing with Guidebook business and updating at this point; at this point, the two pages need to be completely re-pictured/re-texted/basically entirely rebuilt.
Thanks for your help,
