Passenger services (and occasional good trains) on the electrified Freilassing to Berchtesgaden route were operated from 1912 by a class of four 1'C2' electric locomotives (Ep 3/6, later DRG class E36). These locomotives were unusual in that they featured a coal fired boiler for steam heating. The E36 were superceded by four "Bo-Bo" of Class E44 built between 1933 and 1935, and were withdrawn between 1941 and 1943, with two converted to snowploughs. The E44s (later Class 144) were set aside in 1968.
