På spåret is an original format developed by Ingvar Oldsberg for SVT, and he hosted the show for many years.
Author and tennis legend Björn Hellberg was promoted from contestant to permanent Oldsberg sidekick and judge in 1995 after winning for four straight seasons.
The clues, which often include puns and far-fetched word play, get progressively easier as the train approaches its destination, and the number of points awarded for a correct answer accordingly declines.
In between journeys 2 and 3, the original hosts, Oldsberg and Hellberg, used to read a text dressed up as Dr. Watson and Sherlock Holmes, giving progressively easier clues about a specific celebrity.
Following the 50th anniversary of SVT in 2006, this element was replaced by various mini-games, as follows: In recent years, each season have consisted of a tournament with three groups of three teams each.
The show typically feature intelligent, humorous and well-known celebrities, such as sports journalist Lotta Bromé, restaurateur Carl-Jan Granqvist, former weight-lifter Lennart Dahlgren, comedians/TV-hosts Filip & Fredrik, Olympic high-jump champion Stefan Holm, and actor/TV personality Peter Harryson, sports journalist Johanna Frändén.
But also Björn Hellberg, Carl Jan Granqvist, Johanna Koljonen are included among the ones who perhaps are more associated with this television show than anything else, at the time and to the general public at least.
