Cogwheel steamlocomotives HG 4/4 # 704 and HG 2/3 # 6 of the Dampfbahn Furka Bergstrecke (DFB) on the Wiler bridge in the gorge of the Furkareuss. # 704 was on a test run to Tiefenbach this afternoon, # 6 in the work train service up to Furka station. According to the boiler construction, both types have to run "backwards" when going down the mountain (chimney to the mountain), in contrast to the HG 3/4 series, which were built for the line via the Furka and Oberalp passes, which run down chimney first.
