When we purchased our house, we were in a rush to sell the other two and ended up "just moving boxes" and storing them. Storing them in our pool room (floor to ceiling) that is. At Thanksgiving where we were very crowded with only 14 people plus 2 babies, we realized we were in serious trouble for the 32 we were expecting for Christmas Eve. Our solution, oh yeah, let's clean out the pool room. Yipes, we rented a container, move all the cars out of the garages, and started taking things from the pool room. 4 weeks later, Yup, we were still basically moving boxes Christmas Eve morning after working all night long. Managed the event, OK.
For Christmas day we only had 24, and reconfigured the room to feel more spacious (and I actually had time to get a picture). Three sets of trains were needed for the trees.
My "new to me" Lionel RS3 in Christmas paint got duty on the bigger loop of tubular track. With the loco I got 12 of the Lionel yearly Christmas box cars. Originally I wanted to circle the one tree, run a single line around the room to the other tree, but my switch tracks didn't arrive until today (12/26). So the train got shortened to three box cars to fit the smaller loop.
The presents that covered the tracks are gone, but the Lionel Winter Wonderland LionChief set remains. My wife got it for me for Christmas last year. So this is it's first time out of the box. The tank car coupler didn't want to stay coupled so I just fixed it into a knuckle closed position with a piece of bell wire.
