At this early sunny spring morning the two trainsets RABe 525 opposite the city of Thun. They run from each of Thun to Burgdorf, where the two train parts are separated. While driving a part to Wiler, runs the other part of the train in the opposite direction to Sumiswald-GrĂ¼nen, where once lived Jeremias Gotthelf. Then they go back where they are reassembled in Burgdorf.
