Nemesis is a steel inverted terrain roller coaster located at Alton Towers in Alton, Staffordshire, England, United Kingdom. Built by Bolliger & Mabillard, it opened in 1994 and was the first inverted roller coaster outside of North America.

Design[edit | edit source]


Nemesis has four inversions which twist around the ground, trees and the 'river of blood'. The entire ride is built partially into the ground to keep it below the treeline. Nemesis has a pre-drop, a feature employed by the ride manufacturer to reduce strain on the lift hill. When it first opened, Nemesis' track was painted an off-cream colour and its supports were painted black. When the ride was repainted in 2016, the track became white with a rust effect.

Trains[edit | edit source]

2 trains with 8 cars per train. In each car, riders are arranged 4 across in a single row for a total of 32 riders per train.

Trivia[edit | edit source]

The opening in 1994 of The Big One, Nemesis and Shock Wave at Drayton Manor resulted in 1994 being celebrated by United Kingdom's parks and fans as the "Year of the Rollercoaster".[1]

There were originally two other plans for Nemesis (called Secret Weapon 1 and Secret Weapon 2). The first was scrapped due to height restrictions and the second was a pipeline roller coaster. John Wardley, designer of Nemesis, rode a prototype but found it to have a lack of energy. This is when Nemesis, or Secret Weapon 3 as it was then known, was designed.

A sister roller coaster was built at Thorpe Park, named Nemesis Inferno, another B&M inverted coaster themed around a volcano. There is also another ride, called Nemesis: Sub Terra built in 2012. This is an ABC rides dark tower drop themed around the Nemesis creature's egg. Many special effects are used, with the tower drop element only being a small part of the entire experience.
