Santa surprises Asher Dulin (3) during a walk through of the train during the first trip of the season of the Polar Express train trip in St. Louis on November 21, 2017. The Polar Express is a holiday-oriented train that takes children and adults on a 45-minute trip through downtown St. Louis passing colorful painted murials ending at the North Pole, with visits by Santa as hot cocoa and cookies are served.
