 Until 1969, Châtel-St-Denis was also reached by a line of the CEV from Vevey.Railways are very expensive to operate, equip, and maintain and require subsidies from the canton and federal government, thus ways to improve efficiency and reduce expenses have always been considered, thus many adjacent rail lines were absorbed and others abandoned.Due to this regional growth of the system, in 2000, the company was renamed Transports publics Fribourgeois SA (Public Transport of Frbourg)(Freiburgische Verkehrsbetriebe AG), and the city of Fribourg's motor bus and trolley bus lines were integrated.
