This is a model of a coaster
known as a Tivoli coaster. It's called that because the first of many
examples of these models which was ever built was at Tivoli Gardens in
Copenhagen. I've been on that on a quiet evening, and had the mad experience
of doing 10 laps of the ride.
Like the one at Tivoli the coaster serves as a good example of how good
theming can broaden the appeal of a small coaster. If you was to put this
ride on a blank plot of concrete the only people who'd be seriously
interested would be young kids, and the odd adult coaster counter. Thanks to
the fact it's a very nicely decorated ride, with a garden theme that matches
the ladybird cars, this coaster enjoys a broader appeal.
