In 1981 a Glacier Express era came to an end, with the final closure for the winter of the FO line over the Furka Pass and through the Furka Summit Tunnel, between Oberwald and Gletsch. In June 1982, that FO line was replaced by the newly opened Furka Base Tunnel. As a consequence, the Glacier Express not only became disconnected from its namesake Rhone Glacier, but also could now, for the first time, be operated on a year-round basis.
