The first electric loco in the E 77 series was delivered in 1924. The machines came from the factory to the RBD Halle (Leipzig West, Roslau, Wahren and Halle (P) depots) and Munich (Munich main railway station depot). The DRG introduced the standard grey paintwork for electric locos in the year 1927. However the new standard paintwork was not specified until 1933 by the Bavaria network administration, the RBD Munich.
