Sandomierz, February 25,
2024. |
Efforts to design and build electric locomotives for
passenger and express trains in Poland after WWII were not entirely
successful. EP02, which in fact was a derivative of pre-war EL.100 of British
origin, had poor running qualities and was never considered wholly suitable
for large-scale production; only eight examples were built and their service
was comparatively short. Next electric passenger locomotives were imported
from Sweden, East Germany, Czechoslovakia and UK. In the meantime, indigenous (although based on
Soviet VL22M) ET21 freight locomotive went into production at Pafawag
(pre-war Linke-Hofmann) in Wrocław in 1957. This machine was
considered successful and certainly paved the way for more advanced designs.
It was, however, decided to build a license locomotive rather than develop an
entirely new one. The choice fell on British EU06, of which twenty examples
had been ordered in 1961. From the very beginning it was stipulated that
license agreement should follow immediately and until 1965 PKP should have received about 100
examples built in Wrocław under factory designation 4E. These plans turned
out over-optimistic. First locomotive, with service number EU07-001, was
rolled out in December 1964 and accepted for service tests in April 1965.
Until the end of 1966 only four EU07s were accepted and sixteen followed in
1967. Large-scale production started the next year. Despite new service designation, EU07 did not differ
much from British-built EU06 and had similar performance and appearance.
Differences concerned mainly those items of equipment that had already been
manufactured in Poland and thus were not covered by license agreement (such
as compressors or heating devices). Service designation implies that this
machine was suitable both for passenger and freight trains, but from the very
beginning was seldom used for freight service. In fact, due to its
introduction, it was possible in 1970 to withdraw ET21s from passenger traffic,
for which they were certainly not well suited. Production of EU07 at Pafawag lasted until
1974 and totaled 240 examples, the last of which was accepted by PKP in January 1975. Four more were
rebuilt from EP08s in 1976 and 1977. Further deliveries were halted, as
freight locomotives were more urgently needed: this may seem hard to explain,
but in fact electrification did not progress as fast as previously planned
and main effort was concentrated on principal trunk routes, where heavy
freight traffic dominated. As Pafawag was then the sole producer of
electric locomotives in Poland, they had to shift to ET22, which in fact owed
something to EU07 (e.g. electric motors were of the same type). Alternative to electrification was sought in diesel
locomotives and PKP acquired over
1800 heavy road diesels, mostly from the USSR (class ST44). However, due to
drastic increase of fuel prices, this policy had to be revised and in 1981 it
was decided to concentrate available resources on electrification – once
again. As Pafawag was involved in the ET22 program, new passenger
machines were to be built by HCP of
Poznań. This large factory had not built electric locomotives before 1977,
when ET41 made its appearance; this two-section heavy freighter had in fact
been derived from EU07 and had the same traction motors. Original plans
called for about 500 examples, but only 200 were built. Although HCP design bureau produced original
designs of fast passenger locomotives, it soon became obvious that they had
little chances to materialize, if any, especially after martial law
introduction in Poland in December 1981, when import of certain items of
equipment became impossible. It was therefore decided to revive the EU07
program, but on the basis of experience gained with the ET41. First example
of the ‘new’ machine (factory designation 303E) was delivered in August 1983
– over eight years after the last EU07 from Pafawag. In PKP service, machines from HCP were given service numbers from
EU07-301 onwards (last of the ‘old’ batch was EU07-244, rebuilt from EP08-003
and delivered in November 1977). Machines from Poznań differed from earlier ones
mainly internally. First of all, frame was redesigned in order to simplify
manufacture, so new machines were longer by 320 mm and heavier by almost 3.5
tonnes. There were, of course, many differences concerning individual items
of equipment. Wheelsets and engines were the same as in earlier examples.
Externally, the easiest way to distinguish later machines from the earlier
ones – apart from the service number – is the fact that EU07s from HCP had side walls made of riffled
plates and larger pilots. Their production totaled 242 examples, the last of
which – EU07-543 – was delivered in June 1992. Furthermore, three machines
were rebuilt from damaged ET41s (EU07-537 from ET41-036B, EU07-544 from
ET41-088A and EU07-545 from ET41-116A), so the grand total of this class is
489 machines: more than all other passenger electric locomotives in the PKP service combined. In early 1970s a special freight version for sand
railways was designed, intended to replace obsolescent 3Es (equivalent to PKP class ET21); it had different
current collectors and no car heating equipment. This variant was not
proceeded with. EU07s proved quite reliable in service, but soon it
was found out that electric engines were prone to failures as a result of
high rotational speed. It was thus decided to change the main gear reduction
ratio from 79:18 to 76:21. Rebuilt machines were designated EP07, service
numbers being retained. First EP07s appeared in late 1996 and 84 machines
were rebuilt until 2004, including seven from Pafawag. Some were
fitted with LKb535 traction engines of the same rating, but with improved
insulation. Initially it was intended to convert over 200 EU07s until 2005,
but this program suffered considerable delays and new, more extensive
modernization packages were proposed (see below). Until 2002, 57 machines
were withdrawn due to accidents or physical wear. Deliveries of EU07s covered over 27 years and, from
statistical point of view, were moderate: about 18 examples per year. This
cannot change the fact that they are the principal electric locomotives for
passenger and express trains in Poland – and, despite deliveries of modern
motive power, this will not change soon. When EU07-001 was rolled out from Pafawag
for service tests in 1964, this machine could principally be considered
modern; 27 years later, despite all modification, it certainly was not so.
But all efforts to supply more advanced machines in fact failed. EP08 class
(derived from EU07) numbered just fifteen machines; EP09, intended as a major
step forward, was not an unequivocal success. EP23 was a failure, if not
misunderstanding. EU11 and EU43 programs were terminated. Major improvement,
albeit initially rather qualitative than quantitative, came for PKP
InterCity only in 2009, with ES64s from Siemens. However, if you travel through Poland on an
electrified line, your train will still most probably be hauled by a EU07 or
EP07. According to rosters quoted at www.szopa.glogow.pl, in October 2005 PKP had 91 EP07s and 336 EU07s in
active service. EU07-125, built by Pafawag
in 1970 and withdrawn in March 1998, was sold to PTKiGK Zabrze and remains in use, currently with DB Schenker
Rail Polska, with service number changed to 4E-004. This was the first
locomotive of this type purchased by a private operator and for a number of
years remained the sole one used for freight service. It was sold to Wiskol in 2012. In 2008, Koleje
Mazowieckie (KM), which operate local trains around Warsaw, leased
six EP07s from PKP Cargo to haul new push-pull-type drafts supplied by
Bombardier. Further five followed in early 2009. Following the
delivery of eleven brand-new EU47s, completed in August 2011, all were
returned before next September, retaining their white, yellow and green KM
liveries (at least for the time being). As older EU07s were declared surplus
following the acceptance of new locomotives in increasing numbers, they were
purchased by several more companies: - PHU Lokomotiv: 18, - Dolnośląskie Linie Autobusowe: 4, -
Aspekt PHU: 10, - Lozyw Sp. z o.o.: 13, - Orion Kolej: 10, - Metchem: 11, - Tabor Dębica: 2, - PUK Kolprem: 2, - Majkoltrans: 2. Most of them are trading and leasing companies
rather than railway operators. Many of these locomotives were later resold.
Furthermore, in March 2013 four EU07s were sold by PKP InterCity to
the Oleśnica repair works and sold to other companies after overhauls. Modifications of the basic design concerned mainly
various items of equipment (dead man’s handle, improved electric circuit
elements); in some examples, rectangular headlights were fitted. In fact the
need to modernize these locomotives became obvious in the 1990s. Initial
plans included upgrading all existing EU07s to the EP07 standard, as well as
solid-state startup systems for traction engines, improved control systems,
static current converters and new compressors. Due to the lack of financing they
were substantially delayed and cut down. In late 2006, PKP Przewozy Regionalne (at that time a member of the PKP group), who had taken over a
number of EU07s and EP07s, finally launched a modernization program. Initial
intentions were again quite ambitious, including even air-conditioned crew
compartments – or so it appears – but eventually, due to modest financing,
the package has included mainly new main gears with reduction ratio changed
from 79:18 to 76:21, to reduce engine rotational speed (as in EP07), and
removing multiple-control installation. Minor modernizations have concerned
controls, crew seating and windscreen wipers; some locomotives have also been
fitted with new, rectangular headlights and modified, single-arm current
collectors. Lack of multiple-control sockets on the front wall is the most
characteristic external feature of this modernization. New cream-yellow/red
livery did not find much approval among railway fans (to put it mildly) and
promptly earned ‘new’ locomotives the nickname ‘budyń’ (pudding); later
typical PKP InterCity livery, with dominant blue, was standardized,
this time without much discussion. Modernized EU07s are re-designated EP07
but, contrary to earlier practice, are assigned new service numbers from 1001
upwards. EP07-1001 (ex EU07-137) was rebuilt by the ZNTK (Railway Stock Repair
Works) of Oleśnica and rolled out in June 2007. Until mid-2008 this
program included 69 examples, of which two (EP07-1065, ex EU07-024 and
EP07-1066, ex EU07-231) were modernized by Romanian RELOC company of Craiova. Further seven EU07 were found in such
bad overall condition that they had to be written off, although had already
been assigned new numbers (which were later used for the second time).
Despite their relatively low numerical force, ‘new’ EP07s have already become
quite common. More examples may follow in near future. In early 2000s a few
EU07s were modified to operate with passenger trains between Wrocław and
Prague – this included mainly fitting additional equipment required by Czech
railway regulations. In 2011 twenty-four EU07s were modernized by ZNLE Gliwice (now a division of Newag) to the 303Eb standard for PKP Cargo. These locomotives feature
completely redesigned control panel, air-conditioned crew compartment and
many minor improvements. They were assigned new service numbers, from
EU07-1501 onwards. Further six, EU07-1525 through 1530, followed in 2013,
rebuilt by ZNTK (railway stock
repair establishment) of Ostrów Wielkopolski. In December 2012 EU07-1524 (ex
EU07-535) underwent further modification, this time to the 303Ec standard.
Fitted with new single-arm current collector and repositioned multiple
control sockets, and featuring redesigned electric systems, it was
re-numbered EU07-1601. In April 2012 Przewozy Regionalne, no longer
a member of the PKP group, ordered modernization of five EU07s, also
by ZNLE Gliwice. Apart from new reduction gears with the same ratio as
in EP07, modernized locomotives are fitted with new compressors and traction
motor fans, redesigned crew compartment and control panel and new headlights.
Multiple control sockets have been removed. Despite considerable differences
between these locomotives and those modernized for PKP Cargo, they are also referred to as type 303Eb. First example
was delivered in October 2012 and they were given new service numbers, from
2001 onwards. In January 2013 their designation was changed to EP07P, which
was justified by reduced axle load. In all, Przewozy Regionalne purchased ten surplus PKP InterCity EU07s and one EP07; five underwent modernization
and the remaining six are still awaiting decision on their future fate. Undoubtedly the most extensive modernization package
saw light in 2011. Designated EU07A (‘A’ standing for asynchronous), factory
type 303Ea, this variant features new traction engines of much higher rating,
completely redesigned control panel, new brakes and many more detailed
improvements. EU07A, despite being externally similar, is in fact a different
design and shall be described under a separate entry. Mention has also to be
made of ‘class EU07E’: this designation was assigned in 2011 to several older
EU07s (factory type 4E), in order to indicate lower axle load. Some of these
locomotives are distinguished by the letter ‘E’ after the service number. EU07-001, first locomotive of this type from Pafawag,
withdrawn from service in 1998 at the Dębica depot, has been preserved and
currently is kept at the railway stock heritage park in Chabówka. Restoration
was completed in June 2013.
