|Flat Top Tunnel|
|Location||The Polar Express route|
Flat Top Tunnel is a tunnel which the Polar Express runs through on its way to the North Pole. According to the Hobo, there is less than one inch of clearance between the tunnel's roof and the train's. The entrance to the tunnel resembles the face of a monster with the train going through its "mouth" and icicles representing the teeth.
In the film, the Hobo helps Hero Boy get to the front of the train before it enters the tunnel by skiing down the passenger cars. Hero Boy manages to land into the tender just in time, but the Hobo disappears.
In the deleted scene, "It Takes Two," Smokey and Steamer tell Hero Boy and Hero Girl about how the Hobo decided to ride on the roof of the train one Christmas Eve, but ends up getting killed after the train goes through the tunnel. Afterwards, some say his ghost can be seen riding the train every Christmas Eve.
- According to Jerome Chen, the animators created a set that was scaled down to a couple of miles for the scene with the Hobo on top of the train because a normal-scaled set would have been to big.
