Railcars ABe 4/4 ("Tw III") # 51 and # 56 of the Rhaetian Railway are pulling train 4629 from St.Moritz to Tirano along the frozen and lowered (dammed) Lago Bianco (White Lake), crossing the 46 meter long bridge "at the Lake", also called "wild-west bridge". The reservoir, with a maximum water level of 2234 meters above sea level, currently has a very low water level, i.e. it has been completely emptied (as far as technically possible) for electricity production. There has been extremely little precipitation in the catchment area of the lake this winter.
