Yesterday I took a family member to the airport (LAX - Los Angeles Int'l) to fly out for the holidays. As we walked down towards the end of the terminal (LAX terminal 4 - American Airlines) I heard the unmistakable sound of a train whistle. As we approached the rotunda near the end gates I saw a ~20ft XMAS tree. I looked underneath it for the trains but none were to be found. As I looked up, going around the border of the rotunda, 10 ft above the ground, was an LGB large scale Xmas train. At opposing ends were two crossing gates which activated the whistle. Cell phone video and a photo are below.
Where have you seen model railroad/toy trains in unexpected places?
