Infusion is an inverted steel roller coaster at Pleasure Beach Resort, Lancashire, England.

[1][2][3][4] Infusion was relocated from Pleasureland Southport, Pleasure Beach's sister park, where it was known as "Traumatizer" and sponsored by the soft drink "Tizer".

[1][3][8] The ride begins with the train climbing a 109-foot (33 m) lift hill before arching into a steep curved incline.

The train rises up into a butterfly loop- two half loops connected by a corkscrew - before pulling upwards into a banked apex.

A tight helix follows, providing a near miss with the Big Dipper, before the train straightens itself and pulls into a double inline twist.
