Double Looping (Doppel Looping in German) was a model from Schwarzkopf and Ing.-Büro Stengel GmbH.
Three double looping roller coasters were built.
Colossus The Fire Dragon
Debuted in 1981 as Colossus on the German fair circuit, it was operated by Werner Robrahn and Oscar Bruch. It was later sold to Lagoon in Utah, USA where it opened in 1983.
It is the only "Double Looping with additional trackway curve". It has a longer helix at the end, adding an additional 70 metres to the track length.
Operated by Barth on the German fair circuit from 1979 to 1983. It was then sold to Conklin Shows who operated it in the United States until 2008. It is said to have been sold to a park in Pakistan, however its status and whereabouts are now unknown.
According to photographs, this roller coaster first operated at Playcenter São Paulo in Brazil with a single loop as Looping Star in 1981 and 1982. In 1983, the second loop was added and the ride renamed Colossus. It closed in 1986 and was relocated to Dorney Park where it operated until 2008 as Colossus and later Laser. It has now returned to Germany where it operates on the fair circuit as Teststrecke with new trains.
3 trains with 7 cars per train. In each car, riders are arranged 2 across in 2 rows, for a total of 28 riders per train.
