I think this unusual because I don't recall seeing such a double heading from the DB & ÖBB before. The location Faak am See is deep in the south of Austria, well beyond the point where a DB loco would normally travel in Ep. IV. Do you know of any similar double heading ? Perhaps David can decifer the entire list of coaches in this very interesting composition ?
