EU07 is the name for a Polish electric locomotive in service of the Polish railway operator PKP. This locomotive was designed as universal locomotive, and as such is used in both for freight and passenger traffic.

Technical data

EU 07 have driving cabins on both ends of the box. The locomotive is equipped with multiple working device which allows a single driver to drive two coupled engines from one cabin. This engine is able to pull passenger trains of up to 650 t. weight with speed of 125 km/h and freight trains of up to 2000 t. weight with speed of 70 km/h. These figures apply to driving on horizontal railway lines.

History

The EU07 is strongly connected with the EU06 locomotive. The EU06 was a British derivative of the Class 83 locomotive built for the Polish system. In 1959 an agreement was signed with the producer of the EU06, English Electric, under which Poland bought the license for the EU06 and started its production in Pafawag Wrocław, under build number 4E. The first item was finished in 1965, and by 1974 a total number of 240 locomotives had been built. The EU07 locomotives only differed slightly from EU06 thanks to some minor improvements that had been made with comparison to their predecessors.

EU07-348, build by Cegielski

In 1983 the production of EU07 locomotives was re-opened in Cegielski works in Poznań. This new series of locomotives was based on ET41 freight locomotive (which had been built by joining two EU07 locomotives of first run production). Bringing several modifications production number changed to 303E. A total number of 243 items were built and the production continued until 1994 despite this engine was out of date then.

Further innovations

EP07 is a later modification of EU07. Modification has been made in several Rolling Stock Repairing Works since 1995. EP07 locomotives change only class name, but not the serial number.
