Starting in 1920, the electric locomotives of the Bavarian Group Administration (&bdquo, Gruppenverwaltung Bayern&ldquo, ) received a brown painted locomotive body as well as red or black wheels and power train components. The class EG3 goods locomotives supplied to Bavaria from 1924 onwards which were still delivered under the German State Railway numbers 22 001 through 22 031. The renaming to the E 77 series and accordingly the relettering of the locos were not ordered until August 1926. All 31 locos built came into the railway depot of the Munich central station. They were used in goods train service on the electrified routes starting from Munich.
