Big stuff, for me, was taking the plunge into command control by buying Lionel 990 Legacy Command Set and picking up NIB Polar Express Berkshire Whistle Steam 6-18754 ($180) to replace the small motor original we have.
Also bought a 3 pieces of rolling stock, lots of people for the layout (all makes from Lionel to Woodland to Homies, etc) , book on benchwork, half-dozen vehicles, and couple of MTH terminal blocks.
Biggest coupe might have been the backseat full of $1 pumpkins we bought from one of the Amish farms in Ronk. The house is going to look great for Halloween!
Thoroughly enjoyed York and a full day spent in Strasburg at all the train stops - both real and toy. Had a lot of nice conversations with people, learned a few more things, and enjoyed a couple of Indian summer days in a real nice part of the country.
