The DR Class E 11 is a class of electric locomotives formerly operated by the Deutsche Reichsbahn in East Germany. They were later operated by Deutsche Bahn, designated as Class 109.

Technical specifications

The locomotives have a Bo-Bo axle arrangement and a power output of 2,920 kW (3,916 hp).

History

The first two pre-series locomotives entered service in 1961. From 1970 onward, the Class E 11 was designated as Class 211. 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.

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.
