PKP class EP07 is a class of standard-gauge electric locomotives used primarily for passenger trains in Poland. They are rebuilt EU07 class locomotives, which in turn are the direct successors to the post-war British EU06 series locomotives. The only operators of this locomotive series are PKP Intercity and Polregio.
These locomotives constitute the vast majority of electric locomotives still serving the PKP Group today - they are used to drive both light and heavy passenger trains through the whole of Poland.
Since 1995, some EU07 locomotives have undergone a reconstruction, in which new traction motors with a higher permissible operating temperature - LKb535 were installed and the gear-ratio was changed from 79:18 to 76:21. Modifications were carried out, among others..: ZNTK Oleśnica, ZNTK Mińsk Mazowiecki, HCP Poznań, "Newag" Nowy Sącz.
The change of gear ratio did not, however, increase the design speed (misaligned transmission system - hollow shaft bearing on slide bearings), but decreased the engine speed, making it difficult to drive freight trains with this locomotive. It has become easier to maintain the maximum speed of the locomotive while reducing breakdowns. Starting acceleration has also increased - especially at higher speeds, which is realized with less weakening of the excitation (and thus higher motor power). The new LKb535 traction motors, instead of EE541, are adapted to the higher permissible operating temperature. The maximum permitted engine speed for EE541b is 2390 rpm, for EU07 series locomotives with maximum axle rims and 120 km/h, traction engines reach 2380 rpm and EP07 engines in the same situation only reach 1962 rpm, which increases their durability. The rebuilt units kept their rolling stock number (e.g. the EU07-330 locomotive became the EP07-330 locomotive). [1]
In December 2006, 74 EP07 and EU07 class locomotives belonging to PKP Cargo were sold to PKP Przewozy Regionalne. These locomotives have been modernized, the main transmission in EU07 has been changed. In addition, they received new livery, control sockets were dismantled, driver's cabs received thermal and acoustic insulation and new driver's and assistant's seats, and electric wipers and halogen headlights were installed. The locomotives have been renumbered from 1001 upwards.
In the years 2012-2013 5 EU07 of Przewozy Regionalne was rebuilt to EP07P type, they received a new numbering from 2001 onwards. The modernization included installation of static converter, WN and NN cabinets, new panels in driver's cabins, air conditioning and repair of traction motors. On the front a diode display was installed.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
The GE Genesis is a series of passenger diesel locomotives built by GE Transportation for Amtrak, Metro-North, and Via Rail between 1992 and 2001. A total of 321 units were produced.
A traction motor is an electric motor used for propulsion of a vehicle, such as locomotives, electric or hydrogen vehicles, or electric multiple unit trains.
The Polish State Railways was the dominant railway operator in Poland. The company was founded when the former Polish State Railways state-owned enterprise was divided into several units based on the need for separation between infrastructure management and transport operations. Polish State Railways is the dominant company in PKP Group collective that resulted from the split, and maintains in 100% share control, being fully responsible for the assets of all of the other PKP Group component companies. The group's organisations are dependent upon Polish State Railways, but proposals for privatisation have been made.
EU07 is the name for a Polish electric locomotive in service of the Polish railway operator PKP. This locomotive was designed as a mixed traffic locomotive, and as such is used both in freight and passenger traffic.
EP08 is the name for a Polish electric locomotive used by the Polish railway operator Polskie Koleje Państwowe (PKP), produced between 1972 and 1976 in Pafawag, Wrocław. The construction is based on the EU07 locomotive.
EP09 is a Polish electric locomotive used by the Polish railways, Polskie Koleje Państwowe (PKP) and produced by Pafawag of Wrocław between 1986 and 1997.
ET22 is a Polish six-axle electric freight locomotive built by Pafawag from 1969 to 1989. Factory designation is 201E. With 1183 units, it is one of the most numerous standard gauge electric locomotive built in Europe. Further 23 units were built for Morocco as E-1000 class.
ET41 is the name for a Polish electric locomotive used by the Polish railway operator (PKP). Three such locomotives were briefly rented to the Croatian Railways between 1995 and 1996 and were given the designation HŽ series 1081 there.
EN57 is an electric multiple unit used by the Polish railway operator (PKP). It was built for suburban and long-distance services. Presently it is used by Polregio, SKM Trójmiasto, Koleje Dolnośląskie, Koleje Śląskie, Koleje Wielkopolskie and Koleje Mazowieckie companies in Poland.
The ED72 is a Polish four-car, long distance electric multiple unit operated by Przewozy Regionalne (Polregio). Like its cousin (EN71), the ED72 is based on the EN57 and became the basis for its successor: the ED73.
The ED73 was a Polish four-car, long distance EMU operated by Przewozy Regionalne (PR), based on the ED72 and EN57.
PKP Intercity is a company of the PKP Group responsible for long-distance passenger transport. It runs about 350 trains daily, connecting mainly large agglomerations and smaller towns in Poland. The company also provides most international trains to and from Poland. Trains offer Wi-Fi connectivity.
The FS E.632 and E.633 are two classes of Italian railways electric locomotives. They were introduced in the course of the 1980s.
SP30 is a Polish series of diesel passenger locomotives used by PKP.
SP32 is a Romanian series of diesel passenger locomotives used by PKP.
Pesa SA is a Polish rolling stock manufacturer based in Bydgoszcz. The name 'Pesa' derives from the initials PS which stand for Pojazdy Szynowe, 'railway vehicles' in Polish. Pesa is a successor to the Bydgoszcz repair shops of PKP Polskie Koleje Państwowe, Polish State Railways. From the 1950s until 1998 the repair shops operated under the name ZNTK Bydgoszcz, Zakłady Naprawcze Taboru Kolejowego, 'Repair Shop for Railway Rolling Stock' in Bydgoszcz.
The Paxman Hi-Dyne engine was a form of experimental diesel engine developed for rail transport use by the British engine makers Paxman of Colchester. They used variable supercharging to give a constant power output across their speed range.
The Electroputere LE 5100, otherwise known as CFR Class 40/41/42, is a family of electric locomotives built for the Romanian Railways (CFR) for use on the Romanian electrified network. Over 1000 Class 40s were constructed, based on the SJ Rb, by Electroputere (EP) under ASEA license in EPs Craiova Works from 1967 to 1991.
Kolzam RegioVan – a series of railcars produced in Poland, produced by Kolzam in Racibórz in 2003–2005 and by Fablok in Chrzanów in between 2011 and 2012. Kolzam jointly produced: two single units and 10 double units, the eleventh railcar was produced by Fablok. There had not been any triple units produced.
