The Polar Express has come to Aspen Crossing for the holiday season.

The park is using its excursion train to give visitors a chance to believe in the wonders of the season and be kids again.

Manager Donna Biggar says the inaugural run is a special one, that started when she heard about a friend's grandchild who went through cancer treatments....

"They went a pretty rough time and I know there's lots of other families out there that have been going through the same thing, and for me that's all about believing too," she says. "So we've taken our inaugural run and filled it full of families that have gone through cancer treatments throughout the year, or last year and we're taking them away from their troubles and giving them an experience about Christmas that hopefully they'll remember forever."

She says the train has been done up especially for the Polar Express and actors will be giving visitors the full experience from the book and the movie.

Biggar says after boarding the passengers get hot chocolate and cookies and they're read the story. Then the train will take the kids to the North Pole where they'll meet Santa and he'll give them the first gift of Christmas, just as in the book and movie, a little bell.

"I think why it's sold out so quickly is that people now a days are going a little bit away from the material and creating memories with their families," Biggar says. "They're making the word Believe , because the story is so much about believing, it gives a little bit warmer feeling to Christmas."

It runs until Christmas Eve but there are only a very few spots left.
