History
The first two pre-series locomotives entered service in 1961.{{cite web |url=https://lok-magazin.de/leseprobe/quantensprung?page=3 |title=Quantensprung (page 3) |trans-title= |language=German |date= |website=lok-magazin.de |publisher=GeraMond Verlag |access-date=July 1, 2020 |archiveurl=https://archive.today/20200701101708/https://lok-magazin.de/leseprobe/quantensprung?page=3 |archivedate=July 1, 2020 |url-status=live }} From 1970 onward, the Class E 11 was designated as Class 211.{{cite book |editor-last=Rossberg |editor-first=Ralf |title=Deutsche Eisenbahnfahrzeuge von 1838 bis Heute |trans-title=German railway vehicles from 1838 to today |page=203 |language=German |date=2013 |publisher=Springer-Verlag |isbn=9783642957703}} 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. Deutsche Bahn withdrew their last former E 11 locomotive, now designated as Class 109, in May 1998.{{cite web |url=https://lok-magazin.de/leseprobe/quantensprung?page=4 |title=Quantensprung (page 4) |trans-title= |language=German |date= |website=lok-magazin.de |publisher=GeraMond Verlag |access-date=July 1, 2020 |archiveurl=https://archive.today/20200701103256/https://lok-magazin.de/leseprobe/quantensprung?page=4 |archivedate=July 1, 2020 |url-status=live }}
Locomotive E 11 004 was badly damaged in a rear-end collision at Großkorbetha station on 29 August 1969. The manufacturer LEW Hennigsdorf rebuilt it with a car body taken from the current series using usable parts. When it was put back into service, it was given the new company number 211 056 because it no longer corresponded to the original construction and delivery condition.
