Trailblazer hugs the ground closely. As the train approaches the station, it actually goes slightly below the ground level and passes below these wooden beams. Since the train is moving slowly here, there is a slight risk of the train stopping and rolling backward. You can see one short section of track has anti-rollback "teeth" mounted between the rails. This is the same system used on the lift hills, and as the trains pass this section, it makes the distinctive clacking noise usually associated by trains going up the lift hills.
