Bulle is the centre of operations of the former Chemins de fer Fribourgeoisand and its Gruyère – Fribourg – Morat (GFM) meter-gauge railway, plus other railroads. At Bulle are the administrative headquarters, workshops, and, within its modern transportation hub and station, connections between meter and standard gauge lines as well as to many bus lines. Transfer to the wide-ranging trains of the Montreux-Oberland Bernois (Panorama Express) takes place at nearby Montbovon, which provides a convenient connection for travelers from Montreux to the Gruyere line's popular Chocolate Express. 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 Fribourg)(Freiburgische Verkehrsbetriebe AG), and the city of Fribourg's motor bus and trolley bus lines were integrated.
