Millennium Force
The ride has 6,595 feet of steel track. Three different track shapes are used on the coaster, and this picture shows a transition between two track types. The train is passing over triangular track pieces consisting of two running rails connected to a single hollow tubular piece at the bottom of the track. The three tubular steel pipes are connected by square cross-members. In a few feet, the train will pass over the transition between triangular track and square track. That configuration has two running rails, two backbone tubes, and slightly larger square cross-members. In a few slow-speed sections of the coaster, the track is flat with just two running rails connected by cross-member supports.
