In 1946 PKP purchased eight locomotives from the Swedish manufacturer Allmänna Svenska Elektriska Aktiebolaget (ASEA) of a type not used in Sweden.
The locomotives were introduced in 1951–1952. They were designated EP03 class according to PKP system, and numbered EP03-01 to EP03-08. Their main purpose was operating light passenger and freight trains.
The EP03 locomotives were in service until about 1970; the last of the class was withdrawn in 1974.
The only locomotive in operation is EP03-01, preserved in the railway museum in Chabówka.
