## Abstract

A roller coaster track may comprise a laminate and a metal bearing layer. A method of manufacturing a roller coaster track may comprise manufacturing a laminate, manufacturing a metal bearing layer, and assembling the laminate and bearing layer. The bearing layer may be at least partially filled with grout. A method of repairing a wood roller coaster track may comprise removing a layer of laminate, and replacing the layer with a metal bearing layer.

## Claims

### Claim 1

A method of manufacturing a section of roller coaster track, the method comprising the steps of:
creating a design of a curve of the roller coaster track section comprising a laminate and a bearing layer, the bearing layer comprising metal, the bearing layer further comprising a cross-section substantially in a shape of a first parallelogram, the first parallelogram comprising a first side, a second side, a third side and a fourth side, the design comprising a first design element corresponding to the first side, a second design element corresponding to the second side, a third design element corresponding to the third side, and a fourth design element corresponding to the fourth side;
for each of the first design element, the second design element, the third design element and the fourth design element:
determining a planar shape of the side, the planar shape of the side corresponding to such design element as laid flat, and
cutting planar material into a form of the planar shape of the side so as to form the side; and
assembling the cut planar material corresponding to each of the design elements to form the bearing layer substantially according to the design;
laminating at least two strips of non-metal material together to form the laminate substantially according to the design; and
assembling the laminate and the bearing layer to form the curve of the roller coaster track section.

### Claim 2 (depends on 1)

A method of splicing at least two roller coaster track sections, the method comprising the steps of:
manufacturing a first section of roller coaster track according to the method of claim 1, wherein the laminate of the first section is a first laminate and the bearing layer of the first section is a first bearing layer, wherein the first laminate and the first bearing layer each have a first end and a second end, and are assembled such that the first end of the first bearing layer extends beyond the first end of the first laminate by a first length;
manufacturing a second section of roller coaster track according to the method of claim 1, wherein the laminate of the second section is a second laminate and the bearing layer of the second section is a second bearing layer, wherein the second laminate and the second bearing layer each have a first end and a second end, and the second laminate and the second bearing layer are assembled such that the second end of the second laminate extends beyond the second end of the second bearing layer by a second length, the first length being substantially equal to the second length; and
assembling the first section of roller coaster track with the second section of roller coaster track such that the first end of the first bearing layer substantially abuts the second end of the second bearing layer to create a bearing layer splice, and the first end of the first laminate substantially abuts the second end of the second laminate to create a laminate splice, the resulting bearing layer splice and the resulting laminate splice being offset.

### Claim 3 (depends on 2)

The method of claim 2 further comprising the steps of:
prior to the step of assembling the first section of roller coaster track with the second section of roller coaster track, welding a first end of a piece of metal to an interior of the first end of the first bearing layer such that a second end of the piece of metal extends beyond the first end of the first bearing layer; and
assembling the first section of roller coaster track with the second section of roller coaster track such that the second end of the piece of metal extends into an interior of the second end of the second bearing layer.

### Claim 4 (depends on 3)

The method of claim 3, further comprising at least partially filling the first bearing layer and the second bearing layer with grout.
