A few months ago, foolishly I attempted to transport my LEGO Orient Express train set set while it was still affixed to the tracks. I almost made it, but it, uh, had a rapid unscheduled disassembly when I dropped it and it hit the floor. I was in a hurry at the time, I was furious, so I just gathered up the pieces and put it away.
Today, I gathered them up with the instructions and put it back together. There are a few missing pieces, which I will just add to a future order. I might find them in the interim or I might not, but I'd rather just get them and have a few extras.
