The electric passenger train locomotives of Bavarian Class EP 3/5 were the first electric locomotives designed for single-phase AC, 15 kV, 16+2⁄3 Hz working for the Royal Bavarian State Railways. The first electrical services in Bavaria were on the Murnau–Oberammergau line using 5 kV and 16 Hz on 1 January 1905. After 1918 they were reclassified as EP1 20 001 – 005 and taken over by the DR as E 62 01 – 05.
