Operation instruction
Ellok E77 – N
From 1925 onwards, the German State Railway procured
steam locomotives according to standardized construction
principles. The socalled 'standard design locomotives' are
generally known. Far less railway enthusiasts know that
a first electric locomotive design programme existed as
early as 1922. It catered for the procurement of classes
E06, E16, E32, E52, E77, E79 and E91. With 56 units, the
E77 was the most important locomotive of this programme.
The first E77 was delivered in 1924. It was planned to use
the E77 as multipurpose locomotive which was to pull
both freight as well as passenger trains in the Bavarian
and Prussian railway network. The locomotive which was
originally designated EG3 was a design of the Berliner Ma-
schinenbau AG. With a split running gear and a bodywork
divided into three, a good radial movement of axles was
to be achieved. One 20point motor each transmitted its
momentum to the two 1400 mm diameter driving axles via
a Winterthur bias rod drive. Ex works the machines were
taken to the German State Railway administrative units
Munich (loco depot Munich main station) and Halle (loco
depot Leipzig West, Roßlau, Wahren, Halle P). In Munich
they were exclusively used in front of freight trains, in Halle
they were used as multipurpose locomotives, as originally
planned. As the running behaviour was rated unsatisfactory,
Munich handed over all E77 locomotives to Halle in 1943.
In 1946 they were transported to the USSR. Only in 1955
did the last units return. 10 of these were reconditioned
and were in use until 1966. The E7710, called 'Elli', is the
last remaining operational locomotive. It belongs to the
Traffic Museum in Dresden.
