I picked up this long-awaited post-Christmas delivery this weekend.
Note for you that may have one coming, there is a big of an issue with the trucks riding seriously low, particularly the third rail "power shoe" molded into the truck - to the point that when going over switches, they scrape along the center rail of the other track on the switch creating a rather cool and prototypical light show.
In addition, check your cars out - my set as at least one car with half of the Christmas lights not working. It will be going back.
See lousy photo below - note the truck sides sliding across the opposing center rail of my Ross switches....
