History

The first two pre-series locomotives entered service in 1961.[2] From 1970 onward, the Class E 11 was designated as Class 211.[3] Construction resumed until 1976, with 95 locomotives built, and one locomotive rebuilt and renumbered after a rail accident, bringing the total number of locomotives to 96.[2] Deutsche Bahn withdrew their last former E 11 locomotive, now designated as Class 109, in May 1998.[4]
