As well as the motor coaches, the Berninabahn has a couple of locos, Gem4/4 electro-diesels 801 and 802, but they're pretty elusive. Despite having several booked workings, the locos were often substituted if there's a spare motor coach available.
801 led motor coach 48 on train 1627, the 10:45 St. Moritz - Tirano, seen running alongside Lago Bianco at the summit of the Bernina Pass on 15 October 2009.
