Well, I designed and started to build my current layout, known to you guys in my thread, The Mission Valley& Pacific. Which according to me, and Nachoman's poll it's about 10-30% complete.
In addition, I bought nearly all of the engines I've been wanting for years, except two. An IHC 0-4-0 (still want one quite badly, anyone willing to sell?)
Also an P2k SD7/9 in SP bacl widow (also willing to buy!)
Brought nearly all the cars I wanted to do up to NMRA standards, which is a huge accomplishment.
Bought/ Installed my first decoder (digitrax for my P2k ATSF GP7)
Late last year, recieved my First ever Decoder equipped locos (an E7 A+B set.(SP golden state))
learned to maintain my locomotives to well-running condition.
kept a collection of train stuff for my friend.
Continuing my 2nd year at the Niles Depot Train Club
OH! almost forgot! I joined the guage this year!!!

Yay!
enjoyed the last train show to be held at the alemeda county fairgrounds, in Pleasanton, CA. It's practically an institution of my child hood, and a very long tradition for me.
...so all-in-all, not much!
all have a good holiday! Can't wait to hear what you other guys (and gals) have done!
