After cutting ties with the Bremer Theater in 2004, Triebel worked with the Schauspielhaus Zürich (English: The Zürich playhouse) during 2004 and 2005 for a short time, where she acted in Arthur Schnitzler's Das weite Land, a 1911 tragi-comedy about light-bulb Producer Friedrich Hofreiter and his affair with his wife's banker's accountant, Adele. In 2006, she personified "Italy" in the Cologne playhouse's production of "Europa für Anfanger" (English: Europe for beginners).
