From the very start, the MOB had the character of a mainline railway and, at an early stage, through trains with dining and saloon coaches were introduced. The creation of the Golden Mountain Pullman Express in 1931 was unfortunately at a time of world economic crisis and this accounted for its lack of success. The saloon coaches 103–106 built for this train by Compagnie Internationale des Wagons-Lits (CIWL) were sold to the Rhaetian Railway in 1939, where they are still in use (As 1141–44). Two of the original (1913–14 built) coaches have been restored by the MOB and are used for "Chocolate train" services in the summer months, but still regularly find work on the main line "Classic train" services on Sundays throughout the year. The modern successor of this luxury train is the Golden Pass Panoramic Express, which for the past few years has aroused growing enthusiasm.
