The line is owned and operated by Transports publics Fribourgeois (TPF).

The Chemins de fer électriques de la Gruyère (CEG) built another line east from Châtel-St-Denis to Vuadens, opening on 23 July 1903.

At the same time, the CEG opened a line north from Montbovon to La Tour-de-Trême.

[5] In 1942, the CEG merged with two other companies to form the Chemins de fer fribourgeois Gruyère–Fribourg–Morat (GFM).

The line then turns northeast, skirting the Swiss Prealps, to Bulle.
