Prefabricated Track
One of the most significant recent developments in wooden coaster design is Intamin's use of prefabricated track. This design essentially applies the principles of steel coaster manufacturing to wood.
Traditional wooden coaster track is built on site. It is mounted layer-by-layer to the support structure, bent and smoothed to the proper shape, and mounted with steel running plates. Prefabricated track, on the other hand, is manufactured in a factory. It is made of many thin layers of wood that are glued together and then laser cut to the exact shape needed. The track is made in 25-foot (7.6 m) sections, which have special joints on the ends that allow them to snap together like K'Nex pieces. This process allows for far higher precision than could ever be achieved by hand. In addition, the trains for a prefabricated wooden coaster have wheels with polyurethane treads, just like a steel coaster. In contrast, traditional wooden coaster trains have bare metal wheels.
This design results in a ride that is nearly as smooth as the smoothest of steel coasters, and much smoother than any traditional wooden coaster. However, some coaster enthusiasts may find this smoothness to detract from the experience, as it would not have the same character as a traditional wooden coaster. Despite this, all four existing prefabricated wooden coasters are consistently rated among the best wooden coasters in the world.
Prefabricated wooden coasters also benefit from faster construction and reduced maintenance compared to a traditional wooden coaster. The track is simply bolted to the structure, which takes an insignificant amount of time compared to actually building the track. The track also stays smooth much longer than traditional track, which becomes rough rather quickly and eventually must be replaced.

Famous quotes containing the word track:
“Water. Its sunny track in the plain; its splashing in the garden canal, the sound it makes when in its course it meets the mane of the grass; the diluted reflection of the sky together with the fleeting sight of the reeds; the Negresses fill their dripping gourds and their red clay containers; the song of the washerwomen; the gorged fields the tall crops ripening.”
—Jacques Roumain (1907–1945)
