The last of its kind
A Schwarzkopf double-looper from 1983 — precision German steel from the man who invented the modern vertical loop, still running back-to-back inversions with nothing but a lap bar. Tap the markers to explore, or ride it from onboard.
Forty-two years of fire. Anton Schwarzkopf's clothoid loops — the teardrop shape that made vertical loops survivable — get run twice in a row here, back to back, the way only his machines do it. Colossus has anchored Lagoon's skyline since 1983 and stands among the last operating Schwarzkopf double-loopers anywhere on Earth.
About this model. The horizontal track path is the real thing — derived from the community-traced centerline in OpenStreetMap (© OpenStreetMap contributors, ODbL). Elevation is a first-pass profile from published specifications; the loops are injected at their true map position. Scan-accurate geometry lands over the off-season.
