Bavarian EP 5

EP 5 series ( from 1927: Series E 52, 1968: Class 152 ) was an electric locomotive for heavy passenger service of the Deutsche Reichsbahn (DR ) and the German Federal Railroad ( DB).

History

In the first condition laid down by the Deutsche Reichsbahn Bavarian Group Administration procurement program of new vehicles and an electric locomotive for heavy passenger service on electrified lines in Bavaria was provided. From numerous designs they decided on a 2'BB2' locomotive, which should get the same engines as the also planned freight locomotive series E 91

With this new design you went from the previous construction of electric locomotives from a slow running large engine and opted for four small electric motors. The engine was placed in a continuous frame into two groups. Each group has two motors driving a common countershaft through gears. These drives have sloping connecting rods to a jackshaft, which is coupled by side rods with two driving axles. In order not to exceed the permissible axle loads, the machines were each given a two-axle forward or trailing bogie. On the frame of the locomotive body with the two Endführerständen constructed.

The vehicle part was manufactured by Maffei and the electrical equipment of WASSEG, a consortium of AEG and SSW.

The producers provided the locomotives in the years 1924 and 1925 to the Bavarian Group Administration DR, which she took as a generic EP 5 with the numbers 21501-535 in operation. In 1927 they received the designation E 52 01-35. The vehicles were located exclusively in the Bavarian operation sites. By 1945, the E 52 02, 31 and 35 were retired due to the war.

DB Class 152

DB took over the remaining machines, until 1950 then resigned nor the war-damaged E 52 01, 29 and 32. The remaining 29 machines were 1968 Identification Series 152 were available as through the new program of the DB new, powerful electric locomotives in sufficient numbers, these heavy machines, however, were quickly dispensed with. The last machine of this series was retired with 152 014 As early as February 1973.

The E 52 was 140 tonnes, the heaviest electric locomotive that ever ran in Germany, not the DR series E 95, as is often claimed.

The series designation 152 was used in 1996 by the Deutsche Bahn AG again for a new locomotive types, see DB Class 152

Whereabouts

First, their rods were several 152, robbed, used as Trafoloks. These missions ended in the mid-1980s.

Of the 35 built locomotives of the E 52 series only one machine was preserved. The E 52 34 is now labeled as EP 5 21534, inoperable behind is in the possession of the DB Museum in Nuremberg and is since 2011 in the Bw Lichtenfels.

DB 152 025 was used as a transformer for the test field of the AW Frankfurt ( 1983)
