What does the last ticket in polar express say?

The last ticket in the Polar Express doesn't have any words written on it. It's a blank ticket. This is a key part of the story because it symbolizes the belief in magic and the power of imagination.

The conductor tells the children that the first ticket is for those who believe in the magic of the Polar Express, and the last ticket is for those who continue to believe even after they have experienced it.

This concept is emphasized by the fact that the children are allowed to keep their tickets, reminding them to hold onto the belief and wonder they discovered on their journey.
