The PKP Class SU42 No. 504 Bo-Bo diesel-electric locomotive seen here is essentially a Class SP42 with electric train heating, powered by a separate Caterpillar diesel engine. These locomotives are often used on their own for passenger traffic on non-electrified lines.
Class EU07 refers to 2680 hp (2000kW) electric mixed traffic Bo-Bo locomotives equipped with multiple control systems to permit one driver to operate two locomotives in tandem. The EU07 series is closely associated with the Class EU06 locomotives. The EU06 was a British derivative of the Class 83 locomotive but 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.
