Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The generic roller coaster vertical loop is the most basic of roller coaster inversions. Specifically, the loop refers to a continuously upward-sloping section of track that eventually results in a complete 360 degree circle. At the top-most piece of the loop, riders are completely inverted. The vertical loop is not a recent roller coaster innovation. Its origins can be traced back to the 1850s when the French built the Centrifuge Railway. The ride relied on centripetal forces to hold the car in the loop. The ride was shut down after an accident. Later attempts to build a looping roller coaster were carried out during the late 1800s with the Flip Flap Railway at Sea Lion Park. The ride was designed with a completely circular loop (rather than the teardrop shape used by many modern looping roller coasters, see below), but caused neck injuries due to the intense G-forces pulled with the tight radius of the loop.
