Class E 669.3 from Škoda (factory type 61E, later re-classed 183) was the final development version of the basic Co’Co’ electric locomotive design, known as ‘Šestikolák’, or six-wheeler, and dating back to 1961. It differed from its immediate predecessor, class E 669.2, mainly in suspension, slightly modified traction engines and equipment details. Externally these two types were almost identical; later variant could be distinguished by the lack of horizontal metal garnish strip running around the body and one horizontally-divided window in each side wall instead of two.

Class E 669.3 was intended solely for freight traffic. A batch of 43 was delivered in 1971, one more example being rebuilt from 182.063 in 2005. Most went to Slovakia (mainly to the Košice depot), only eight were initially assigned to the Olomouc depot, but were also transferred to Slovakia before the end of 1980. After the break-up of Czechoslovakia, all 183s became the property of ŽSR. In early 2011, 37 of these still remained with ŽSCS (Železničná spoločnos Cargo Slovakia, a.s.), the sole operator of this type. Class 183 was the last six-axle electric locomotive built in quantity for ČSD. Its intended replacement, class 184.5 (Bo’Bo’Bo’), which appeared in 1994, was built only in four examples, all finally going to an industrial operator. Class S 669.0 for mixed traffic of 1963 remained only a prototype, which finally ended up in the Škoda factory museum in late 1990s.

Although first ex-ČSD six-axle locomotives appeared in Poland in late 2005, class 183 from  ŽSCS followed only almost six years later. The first example was 183.039-7, which was acquired by Tarnów-based PUK Kolprem and arrived in June 2011; in November it was transferred to Pol-MiedŸ Trans. Until late 2014 more examples followed, bringing their total number to 22. Apart from three operated by PUK Kolprem, they went to Pol-MiedŸ Trans (six), STK (five) and Rail Polska (eight). They have been fitted with modified current collectors and equipment conforming to relevant Polish standards. Despite their age, these locomotives are still highly valued for simplicity and reliability.
