Prior to 1978, LEGOLAND-branded sets were focused mainly around buildings and vehicles which were intended to function more as static models. In 1975, a precursor to the minifigure was introduced, in the same scale but without moving parts. These "stiffs" (as they are nicknamed by LEGO enthusiasts) were still unable to ride the vehicles. This was changed with the new minifigures - in 1978 in Europa and 1979 in North America the first vehicles that were minifigure compatible were also released. In 1980, the Trains theme was completely revamped to complement the Town sets. By 1983, the remaining vehicle based sets that were not minifigure compatible had been discontinued.
