A major focus for many of these clubs is the operation of a club track or miniature railway for members' model live steam locomotives. These tracks are often run publicly and form part of community recreational and tourism infrastructure in their local area. Model engineering clubs and societies often cater too for model engineering interests beyond locomotives. Due to the inherently dangerous nature of live steam, clubs and societies are responsible for administering safety regulations, insurance and specialist boiler codes that cover both members and the public. To this end, model engineering clubs and societies often affiliate into national bodies that can lobby government to maintain the historical privilege they have to self-regulate their own safety standards.
