Since Poland needed new electric locomotives after the war and did not yet have its own industry in this sector, these continued to be procured from foreign suppliers. Based on the experiences with British companies in the thirties, the electrical components for the production of seven four-axle electric locomotives were ordered there again, which were to be used again on the Warsaw light rail system. The complete locomotives were manufactured at the Pafawag wagon factory in Breslau. In 1957 an eighth locomotive was built with local electrics, which had a slightly lower output. The series designation at the PKP was first E110, then E02 and finally EP02.

Technically, the locomotives had a lot in common with the EL.100. Visually, they differed primarily in a more modern, streamlined locomotive body. Since the electrical equipment was no longer state-of-the-art and there were quality problems in the manufacture of the mechanical parts, many teething problems had to be repaired first. Nevertheless, they were used in express service until the 1960s and later in front of regular passenger trains. As more and more technical problems arose, the maximum speed was reduced to 70 km/h, which was soon followed by the removal from active service. After retiring from active service, some examples spent many years as stationary heating locomotives for passenger trains, the last one until 1992.
