The Ge 4/4^II 631 on the Albula-I viadukt

The early afternoon Pontresina to Thusis freight train is hauled by a Ge 4/4^II that also does the dawn GmP (mixed freight and passenger train) to the Engadin and on secondary season weekdays moves the normal REX-cars of the Bernina-Express from Samedan to St. Moritz (while the panoramic cars go on to Pontresina and the Berninabahn as they do in the season and on weekends when the BEX is a separate train from Chur to Tirano all along).
