 These mid-1970s, Town sets had buildings and vehicles functioning more as models, with minifigures unable to ride the vehicles, which continued with the new minifigures until the early 1980s, when buildings and vehicles consistently were designed to be compatible with minifigures.All sets were originally released under the "Legoland" label until it was discontinued and replaced with "Lego System" branding in 1991.Eventually, different subthemes under the "Town" brand were used to tie together related sets, such as police, coast guard, emergency services, airport, road rescue, trains, fire, and harbour.
