Until 1982, the Glacier Express operated only in the summer months, because the Furka Pass and the Oberalp Pass were both snowed over in winter. Initially, the train was made up of first to third class salon and passenger coaches, supplied by all three of the participating railway companies. Between Chur and Disentis/Mustér, passengers could enjoy a hot lunch in a Mitropa dining car. From 1933, the Glacier Express through coaches were attached to normal passenger trains between Brig and Zermatt.
