Heavy drafts have always been typical for Polish freight traffic; no wonder, thus, that first indigenous electric freight locomotive, ET21 (726 examples built between 1957 and 1971), with continuous rating of 2040 kW, soon became too weak. Double-heading was certainly not an economical solution and, with rapid progress of electrification, more powerful freighters were obviously necessary. ET21, based to a certain extent on Soviet VL22M of early 1940s, was a simple and straightforward machine with little – if any – potential of further development. Six-axle EU20, supplied from Eastern Germany, was neither reliable nor particularly modern. Specification for a new freight locomotive was submitted in 1966, initially with an intention to produce a universal machine with maximum speed of 125 km/h, suitable also for heavy passenger trains – hence proposed class designation EU22 (factory type 7E, later changed to 201E). New locomotive owed much to British-built EU06 and its later Polish license variant EU07. In particular, traction motors were of the same type, as well as their suspension and many other items of equipment.

First prototype from Pafawag factory of Wrocław, finally designated ET22-001, was rolled out in November 1969 and tests began in December, ET22-002 joining next February. Results were basically satisfactory and next ten machines were delivered in 1971. New locomotive, compared to ET21, offered almost 50% increase of rated power and tractive effort and was soon accepted for mass production. Between 1971 and 1989, 1207 examples were supplied, which makes ET22 the most numerous electric locomotive type ever built in Poland and in fact also in Europe. First ET22s were soon found prone to derailing, so from ET22-122 onwards connection between trucks and body was redesigned (which also resulted in reduced vibration and improved crew comfort). This modification was between 1994 and 1996 retroactively introduced in 27 earlier examples that still remained in service. Last machine with earlier suspension variant in active service was ET22-101, written off in 2001. Only two examples of this version (ET22-010 and -101) still exist.

Although considered a universal locomotive at the design stage, type 201E finally emerged as a freight machine, mainly due to PKP priorities. Type 201Ea, delivered in March 1973, was an attempt to develop ET22 into a fast – at least for that time – passenger locomotive (maximum speed 140 km/h). Reduction gear ratio was changed from 79:18 to 73:22, but running qualities left much to be desired and after prolonged tests the idea was abandoned. The sole example, designated EP23-001, was converted in 1979 to the ET22 standard and designated ET22-121 (this service number was used for the second time, the first ET22-121 being written off two years earlier). 201Ed (later re-designated 103E), with the same reduction gear, LKa535 traction motors, modified trucks and maximum speed 160 km/h, never left the drawing board. During 1974, several modifications were introduced, mainly in suspension, in order to improve running qualities, but type designation remained unchanged. 201Eg, built in 1975, was the export variant for Moroccan state railways ONCF, with redesigned body (different vehicle gauge), LKa535 traction motors and many minor modifications. 23 examples, supplied between 1975 and 1976, were designated ONCF class 1000 and given service numbers from E-1001 onwards. 201Ec of 1977 featured multiplied control, further truck and suspension modifications and various minor improvements. It was initially intended to standardize this variant, but the idea was abandoned and only two examples were built, with service numbers ET22-501 and ET22-502 (later ET22-701 and ET22-702, finally ET22-1001 and ET22-1002). Many other minor modifications were introduced during production and individual batches differed externally in shape and location of side windows, air inlets and vents. Type designation, however, was not changed and apart from above-mentioned examples all ET22s built until 1987 were delivered as type 201E. For some unknown reason, later ET22s were designated type 201Eh, although in fact no modification justified this change!

Due to decrease of freight traffic and lack of passenger locomotives, ET22s are quite often used with passenger trains; their running qualities in this role are, however, far from satisfactory. In fact, running qualities have never been the strong side of ET22 and older ET21 was even considered superior in mountain regions.

In early 1970s preliminary specification was drawn up for a 6000 kW Co’Co’ electric locomotive, to be built in several variants, of which the fastest was to attain 200 km/h. Plans to build 720 such machines until 1985 proved sadly over-optimistic. New machine failed to materialize even in a prototype form and thus ET22, commonly nicknamed ‘Byk’ (Bull), is still the basic electric freight locomotive in PKP service. According to rosters quoted in SK, their number reached its peak in 1991: on January 1 PKP had 1171 examples. During next six years they dwindled to 1153 and on January 1, 1999, PKP had 1024 ET22s (of 1184 delivered). This type is also used by other operators (some examples having been purchased via scrap-disposal companies!). In mid-2006, CTL holding had seven ex-PKP machines; as state railways were not eager to sell further locomotives to the potential competitor, three examples withdrawn from ONCF service (E-1003, E-1018 and E-1021) had been purchased in 2003. Two more ex-Moroccan machines were intended to follow in 2004, but this finally failed to materialize. Jn January 2012, however, further eight ex-ONCF locomotives arrived in Poland by sea from Casablanca and were brought to the Oleśnica repair works. They were thoroughly overhauled and modernized to the 201Eo standard (modified crew compartment with air-conditioning, single-arm current collectors and several minor improvements). Six were sold to Rail Polska and two to PHU Lokomotiv. Until March 2015 further six ex-PKP ET22s were modernized to this standard and sold to various private operators. Moreover, 201E-277 (ex-PKP) was used by Kuźnica Warężyńska sand mine and finally went to DB Schenker Rail Polska in April 2010. Private operators don’t use any consistent designation system, so their machines are designated as ET22 or 201E plus service number (usually serial, but sometimes an alphanumerical designation, e.g. CTL ET22-R004 is ex-PKP ET22-791).

Basic ET22 design goes back to the 1960s and further modifications – apart from trucks and suspension – were generally restricted to details. Plans from late 1990s stipulated that about 50 locomotives of this type should be modernized by 2000, with options for further 300 between 2001 and 2005 and 200 between 2006 and 2010. It was intended to fit new ac traction motors in completely new trucks and modify the suspension, which had never been a strong side of the basic design. These plans had to be cut down substantially and first major modernization was undertaken only in 2002. The first modernized machine, designated type 201Em, with service number ET22-2000 (ex ET22-315), was rolled out in June 2004. Main effort was concentrated at improving running qualities, so trucks and suspension were thoroughly redesigned. Electric equipment and control systems were also modified, although traction motors remained unchanged. Control panel was completely redesigned. Externally – apart from minor differences, new livery and out-of-sequence service number – the modernized machine was easily identified by different headlights and rectangular air intakes to air conditioning installation, the latter being fitted for the first time. Service tests began in August 2004 and results were considered satisfactory, but next step came only in 2007, when a decision was taken to bring up further 49 ET22s to this standard during next two years. A contract for modernization of four examples was signed with ZNLE (Electric Locomotive Repair Works) of Gliwice in September and first two of these, ET22-427 and ET22-569, were delivered in 2008. Due to financial restrictions the number of 201Ems was finally cut down to 28 examples and the entire batch was completed in mid-2010. Of the remaining 22 ET22s, twenty were finally modernized to the 201Ek standard, wherein old trucks and suspension have been retained. Modernized locomotives were given new service numbers, from ET22-2000 onwards, and the last one, ET22-2047 (ex ET44-488), was outshopped in January 2011.

Yet another modernization version, more ‘modest’ compared to two above-mentioned ones, was proposed in 2011. Designated 201El, it is restricted mainly to electrical equipment, air conditioning units and driver’s cab details. It was introduced during major overhauls at the ZNLE Gliwice and first batch numbered seventeen examples. They were given new service numbers, from ET22-1201 onwards. First of 201Els (ET22-1201, ex ET22-688) was completed in January 2012 and the last one, ET22-1217 (ex ET22-593) was outshopped in September 2012. All were assigned to the Katowice regional management. Until now (mid-2017) no more modernizations followed.

Many Polish locomotives of unquestionable historical value have been scrapped, so it is certainly worth mentioning that ET22-121 (ex EP23-001) has been saved. After withdrawal, it somehow managed to find its way to the rolling stock heritage park in Jaworzyna Śląska (now Industry and Railway Museum), where it can now be seen. Its condition is far from perfect, but – considering the attitude of its present owners – things should soon improve. According to recent information, this locomotive is intended for restoration in near future, providing that adequate funds are available.
