The "Moyse" built diesel shunters Gm 3/3 # 231 to # 233 of the Rhaetian Railway were withdrawn, replaced by the new Geaf 2/2 # 20601 to # 20607. The association Dampfbahn Furka Bergstrecke (DFB) purchased this 3 diesellocomotives (at least 1 for spare parts) for shunting service in Realp and in the Furka summit tunnel. The locomotive have no cogwheel drive. To bring the "Moyse" over the Oberalp pass to Realp, each 34 ton locomotive had to be pulled in a separate train, behind the HGe 4/4 II # 103 "Chur" of the Matterhorn-Gotthard-Bahn (MGBahn) and 5 passenger cars behind, serving to brake in the rack sections. The first of this trains with Gm 3/3 # 233 is slowly running down the mountain between Nätschen and Andermatt.
