In one of the shots in The Polar Express, you can see a newspaper. There’s a photo showing Santas on strike holding signs that reference “Lone Pine Mall.” If you think you’ve heard it somewhere before, you are right.

This is the name of the mall from the 1985 film Back to the Future. The viewers even found an explanationfor this coincidence: the Polar Express is set during the Christmas of 1956 and Back to the Future was set in 1955. So the characters lived at the same time, which means they could visit the same malls.
