Roller coasters, or coasters for short, are key components of any amusement or theme park. Often forming as central features to an attraction, rollercoasters can appeal to a variety of audiences, varying in size, appeal and intensity.

A standard layout typically includes a station for boarding, propelling mechanism (chain or launch), circuit track and brakes.

Roller coasters traditionally fall under two main categories, defined by their main construction material.

Wooden coasters (or “Woodies” as named by its passionate fanbase) are the most traditional. The oldest wooden rollercoaster still in operation is “Leap the Dips”, found at Lakemont Park. The Pennsylvania, US-based structure has entertained visitors since it opened in 1902.

Metal coasters, unlike their wooden counterparts, can come in either sit down or suspended form. The latter sits riders underneath the track.

Hybrid coasters are a relatively modern invention, combining some of the best features of wooden and metal coasters.

As with any ride, a number of safety mechanisms are used on roller coasters to guarantee riders’ safety. The “block system” utilises a number of block brakes that ensure roller coaster trains are kept from colliding, by keeping each vehicle on a separate section of the track.
