The company is a railway operator with both narrow and standard gauge lines centred in the town of Bulle. The main line of the narrow gauge network runs from Palézieux railway station (at Palézieux-Gare), on the SBB main line from Bern to Lausanne, via Châtel-St-Denis and Bulle to Montbovon. The short Bulle - Broc branch, which leaves this line between Bulle and La Tour-de-Trême, serves the nearby Nestlé (formerly Cailler) chocolate factory. The company also operates two standard-gauge lines, between Bulle and Romont and Fribourg - Ins via Murten/Morat. Trains on the latter route have been extended and now operate a regular interval service Fribourg - Murten - Ins - Neuchatel, taking them on to BLS tracks (Ins - Neuchatel).
