In 1958, well-known Czechoslovak Škoda works of Plzeň built two electric locomotives with factory designation 23E1 (ČSD class E669.0, later 180). These were the first six-axle electric locomotives built in Czechoslovakia after WWII. Their design was based on the successful four-axle E499.0 and they differed between themselves in many details, being basically experimental machines (however, according to AL, 180.002 was still operational with ČD in mid-2006). In 1961, their improved variant with factory designation 31E1 was ordered by ČSD in quantity and eighty examples were initially built. Second batch, numbering seventy machines, differed mainly in more powerful traction engines (factory type 31E2). Both variants were classed E669.1, this designation being later changed to 181; they were commonly nicknamed ‘Šestikolák’ (literally, ‘six-wheeler’), due to the Co’Co’ axle arrangement. Last, 150th locomotive was delivered in 1962. They were later developed into improved variants E669.2 and E669.3 (later classes 182 and 183, respectively), also built in series. 181s still remain in use with ČD, which in early 2006 had 48 examples. Further two are used by OKD Doprava a.s. Ostrava.
As with many other Czechoslovakian locomotives, much larger orders came from the USSR. There were several individual variants, in SŽD service designated class ChS2 (ЧC2 in Russian script). First two prototypes (factory type 25E1) were built in 1958. They differed in having more powerful AL4846zT engines with one-hour rating of 586 kW and reduction gear ratio changed from 84:37 to 80:41. Their maximum speed was 160 km/h (in service reduced to 140 km/h) and of course they were passenger locomotives. Production variant (factory types 34E1 through 4) differed in still more powerful AL4846eT engines (700 kW), strengthened trucks and modified equipment; until 1964, 303 examples were delivered. In 1962, ChS2-232 was fitted with rheostatic braking system and served as a prototype for the modified version, classed ChS2T (T stood for ‘tormoz’ – brake). Until 1973, 639 examples were delivered in nine batches, differing in minor items of equipment (factory types 53E1 through 9). Final version, which retained the ChS2T designation, was fitted with AL4846dT engines (680/770 kW) and featured improved rheostatic braking system and entirely new, angular body, which made it externally completely different from its predecessors. This final variant (factory types 63E1 and 63E2) was built between 1974 and 1976; in all, 120 examples were delivered, bringing the grand total in the SŽD service to 1062. They still remain in use in large number with RŽD in Russia; several are probably used also by Ukrainian railways.
Polish state railways PKP never ordered these machines. They were substantially more powerful than six-axle ET21, but compared to ET22 had less power and less tractive effort (35 and 42 tonnes, respectively), being slightly heavier. First 181s appeared in Poland only in mid-2000s and these were second-hand ex-ČD machines. Their withdrawal has resulted from certain surplus of freight locomotives in Czech Republic; moreover, it was decided to supplant six-axle machines with four-axle ones, due to their lesser impact on track. First three examples, 181 009-2 (4243/1961), 181 039-9 (4273/1961) and 181 116-5 (4540/1962) arrived in Poland in November and December 2005. According to data provided by Petr Štefek (thanks a lot!), until March 2008 as many as 29 181s were obtained by three private operators. Another source (SK 7/2009) gives over 40 examples transferred to Poland until mid-2009, not all having been impressed into service. In early 2014 Polish operators had 50 locomotives of this type. Initially the largest fleet was that of PCC Rail; some of them carried the company’s deep blue livery. Following incorporation of this operator into DB Schenker Rail Polska they were disposed of, mostly going to Lotos Kolej, which currently operates 34 examples. STK has twelve 181s, plus some more leased to Lotos Kolej and included in their total. Transoda has three and Koleje Bałtyckie just one. The above total does not include 181.121 from the PCC fleet, which was badly damaged on December 13, 2012, following derailment, and was later written off. Some 181s have been leased via ALZA leasing company: pretty complicated indeed – I do feel more at ease with technical issues! As far as I know, only Transoda company have re-designated their first locomotive of this type as ET23-001.23 (last two digits identify the company and their coincidence with class designation is purely incidental), i.e. in the PKP fashion. Next two have retained their original numbers. Despite their age – well over forty years – these locomotives are still very useful and often encountered throughout the country. They have, however, been outnumbered by class 182, their direct development.
