Upon the resumption of daily through trains in 1948, the dining car service was extended from Disentis/Mustér to the top of the Oberalp Pass. Between the 1950s and the 1970s, both the BVZ and the RhB introduced new locomotive classes that, when attached to the Glacier Express, enabled reductions in schedule times. Meanwhile, the dining car service was extended further, to Andermatt.
