Between 1943 and 1946 three class Ge 2/4 electric locomotives with a center cab (so-called "flat irons") were rebuilt and given a new class number in order to have steam-free switching operations at the stations in Chur and Landquart. The savings in weight also made it possible to install a storage battery layout in road number 211. This locomotive was then designated as the class Gea 2/4
