The DRG Class ET 171 (since 1968 DB Class 471/871) is a three-car electric multiple unit train built for the Hamburg S-Bahn.

History
The first electric Hamburg S-Bahn trains appeared on the Hamburg-Altona City and Suburban Railway in 1907. In 1937, the main-line railway operator, Deutsche Reichsbahn, decided to switch the current collection method from overhead catenary (AC 6,3 kV/25 Hz) to third rail (DC 1,2 kV). The new Class ET 171 trains were built to replace the old overhead line trains. The first unit appeared in Hamburg in December 1939.[1]
Description
1939-1974
The first 47 trainsets were built from 1939 to 1943. There were to have been 100 units in total, but the World War II interrupted production and it was not resumed until 1954. A further 21 units were built from 1954 to 1955 in order to enable the overhead line traffic to be withdrawn. Additional 5 units (171 082-086) were built in 1958 to service the new line between Hamburg Central Station and Bergedorf.
1975-today
In the 70s and 80s, some trains received a new livery, alike the one of the new Class 472 trains. Retirement began in the late 80s for single trains, in late 90s most trains were taken out of service and replaced by the Class 474. The last 471s were retired from regular service in October 2001. Unit 471 082 from 1958 is still operational and is used as a heritage train. Also 471 039 and 471 062 are still existing but can not be moved by own power.
Equipment
All units had a dynamic brake to reduce the wear of the brake pads. All doors can be automatically closed from the driver's cab by the train driver but can be opened again after a short time. This was possible until the 1970s due to safety reasons. All trains had a 2nd class in the end cars and a 1st class in the centre car. The first class was removed from all Hamburg S-Bahn trains in November 2000. The lighting was done by light bulbs. All trains are equipped with Sifa all the time. In 1965, the trains were also equipped with PZB to make the train traffic more safely.
