The electric passenger train locomotives of Bavarian Class EP 3/5 were the first electric locomotives designed for single-phase AC, 15 kV, 16+23 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.[1][page needed]

On 1 July 1912 operations began on the line from Garmisch to Scharnitz and, on 28 October 1912, electric services started. From 28 May 1913 electric trains also started running on the Garmisch and Reutte in Tirol railway. For this purpose five locomotives of Class EP 3/5 20 001 – 005 were purchased by the Bavarian state railway and placed in service in 1913. They mainly worked the section from Garmisch to Reutte. For the opening of electric services on the line from Bad Reichenhall to Berchtesgaden one engine (EP 3/5 20 001) was loaned to Freilassing. The engines proved themselves well in service and were stationed at the Garmisch locomotive depot; some were still in service until 1955.

Three engines remained in service with the Deutsche Bundesbahn after the Second World War; the others had been retired in 1939 and 1941. The last one to be paid off was no. E 62 001 in 1955. It was stored until 1965 in the Freimann repair shop and later dismantled.[2]

The drive unit of no. E 62 001 has been preserved in the Nuremberg Transport Museum. During the fire in the Nuremberg-Gostenhof roundhouse in 2005 it was badly damaged.[3]
