The EU07 locomotive comes from the English locomotive of the English Electric company, which had the designation EU06 in Poland.
In Poland, the licensed production of EU07 locomotives was commissioned to the Pafawag factory in Wrocław. English documentation had to be converted into Polish documentation by changing the English dimensions to the SI system. This required rounding off some values. At the factory, the locomotive was given the factory symbol 4E, and at the Polish State Railways, the designation was EU07. The production of the locomotives began in 1963 and continued until 1974. According to other sources, production continued in the period 1965–1977. In 1977, the assembly line was switched to the production of ET41 electric locomotives. Over 11 years, 240 EU07 locomotives were built, although 300 were planned. The number of EU07 locomotives built allowed to meet the most important needs in the operation of passenger, fast and express trains in Poland on electrified lines.
The first EU07-001 after service went to the Railroad Museum in Chabówka. The locomotive is in its original painting.
