A roller coaster is a type of amusement ride employing a form of elevated railroad track that carries passengers on a train through tight turns, steep slopes, and other elements usually designed to produce a thrilling experience. Trains consist of open cars connected in a single line, and the rides are often found in theme parks around the world. Roller coasters first appeared in the 17th century, and LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, based on the Switchback Railway which opened a year earlier at Coney Island.
Kings Dominion is an amusement park in the eastern United States, located in Doswell, Virginia, twenty miles (30 km) north of Richmond and 75 miles (120 km) south of Washington, D.C. Owned and operated by Six Flags, the 280-acre (1.1 km2) park opened to the public on May 3, 1975, and features more than 60 rides, shows and attractions including 13 roller coasters and a 20-acre (8.1 ha) water park.

A stand-up roller coaster is a roller coaster where passengers aboard a train stand throughout the course of the ride. The first manufacturer to employ the format was TOGO, a Japanese company that converted two traditional roller coasters in 1982 to stand-up configurations. Arrow Dynamics followed suit in the United States the following year with their own conversion. The first roller coaster designed from the ground up as a stand-up coaster was King Cobra, built by TOGO, which opened at Kings Island in 1984. Intamin and Bolliger & Mabillard (B&M) have also designed stand-up models beginning in the 1990s, with the latest opening in 2023 as Pipeline: The Surf Coaster in SeaWorld Orlando.
Bolliger & Mabillard, officially Bolliger & Mabillard Consulting Engineers, Inc. and often abbreviated B&M, is a roller coaster design consultancy based in Monthey, Switzerland. The company was founded in 1988 by engineers Walter Bolliger and Claude Mabillard, both of whom had worked for Giovanola.

More than 40 million people had ridden Magnum by 2009.
