Later in 1919 the locomotive operated scheduled services - commuter and freight - between Bern and Thun, and later to Spiez. In November 1919 she operated scheduled services to Brig, together with Be 4/6 12301. Later those services continued together with the Be 4/6 12303-12342 series locomotives, delivered in April 1920, over the Lötschberg line. At the inauguration of the electric service on the Gotthardbahn this locomotive was unique; its only trips over the Gotthard were the transfers to the Bellinzona workshop.
