Railcars ABe 4/4 ("TW III") # 54 and # 51 of the Rhaetian Railway, built in 1988/1990 by SWA and BBC, are pulling the regional train 4629 from St.Moritz to Tirano along the Lago Bianco (White Lake) on the Bernina pass, about 2250 meter a.s.l. It is planned that from the timetable change on December 11, these railcars will (probably) no longer pull regional trains, but only the seasonal BERNINA EXPRESS trains between Tirano and St.Moritz and vice versa.
