Electric Locomotive Siemens ES64U4-D, EU44-008 Husarz.
EU44 Husarz Electric Locomotives.
EU44 Husarz is the Polish name of the EuroSprinter ES64U4 electric locomotive, which was produced by Siemens.
In the 1990s, the idea of building a platform of universal electric locomotives was born, which could also operate on various electric tractions. This is how the EuroSprinter locomotive family was created, serial production of which started in 2000. Since 2001, a universal two-system locomotive has been produced and ordered by various European countries.
On September 2, 2006, an experimental EuroSprinter with a measuring wagon broke the speed record for conventional locomotives with a result of 357 km/h.
EU44 locomotives for Poland.
In August 2008, an agreement was signed for the purchase of 10 EuroSprinter ES64U4 Taurus locomotives by PKP InterCity. In Poland, the locomotives were marked EU44 Husarz.
In mid-November 2008, the first locomotive was presented at the Siemens factory in Linz. On December 18, 2008, the locomotive came to Warsaw for testing. On the night of May 28-29, 2009, during tests on the Central Railway Main Line, the locomotive broke the speed record for a train consisting of a locomotive and wagons on Polish tracks, achieving a speed of 235 km/h.
In May 2009, the second locomotive arrived in Poland. On October 12, 2009, the first ride with passengers of the first EU44 Husarz locomotive took place on the Warsaw Grochów - Kutno route. On this section, the EU44 Husarz locomotive drove the Warsaw - Berlin - Express train. Production of the EU44 Husarz for Poland lasted from 2008 to 2010. On June 21, 2010, the last tenth Husarz was delivered to Poland.
For the 2012 European Football Championship, EU44 Husarz locomotives were covered with decals referring to the championship. Six locomotives ran in the colors of the countries taking part in Euro 2012, and four in the colors of the Polish host cities. At the same time, 10 EP09 electric locomotives were wrapped in the colors of the other 10 countries taking part in the competition.
EU44-008.
EVN number: 91 51 5 370 008-2 (PL-PKPIC). Factory number ES64U4-21667/2010. 2010 year of production.
The locomotive was produced on April 1, 2010. It was handed over to InterCity on May 1, 2010, as the 8th copy of 10 ordered. The locomotive was blue and gray in color. In April 2012, the locomotive was wrapped in the "Wrocław Stadium" colors. In June 2014, it was repainted in black and white. In February 2015, the P3 level was repaired. in March 2015, the colors were changed to blue-gray. In February 2017, the locomotive was in pink veneer. In 2018, the decor was changed to "White and Red Independent". In 2019, the colors are blue and gray.
EU44 Husarz design.
Siemens EuroSprinter ES64U4 (EU44 Husarz) is a standard-gauge, universal multi-system (four-system) electric locomotive. Bo'Bo' axle system. The locomotive can operate under traction: AC 15 kV 16.7 Hz, 25 kV 50 Hz, DC 3 kV, DC 1.5 kV. The locomotive traditionally has two cabins at the ends of the body. The middle part is the engine room, which is equipped with a corridor running down the middle. A cable tunnel was placed in the channel, under the corridor floor.
The locomotive has two two-axle bogies. The frame of the trolley is welded from steel profiles. The axles of the wheel sets rotate in a set of roller bearings, maintenance-free up to the P5 maintenance level. The electric motor with the axle of the driving wheels is connected to a gear with helical teeth. Braking is performed by an additional braking shaft, which has two friction discs with shoes. The braking shaft is rotated by an additional gear connected to the main gear disc on the wheel axle. This solution is necessary due to the maximum speed of up to 250 km/h.
The drive system consists of four asynchronous motors, powered by a pulse inverter, with variable voltage and frequency. The engines have a power of 4 x 1,640 kW, and the short-term power is 4 x 1,750 kW. The locomotive has a system for recovering energy during braking, i.e. the so-called recuperation. The locomotive has four pantographs placed in pairs. Pantograph 1 and 4 receive energy from the AC network (DAS 250.14 type), and pantograph 2 and 3 receive energy from the DC network (DAS 250.11 type).
Data T-T EU44 Husarz:
Locomotive power depending on traction: 6,400 kW (AC), 6,000 kW (3 kV), 4,200 (1.5 kV). Maximum speed: 200 km/h (3 kV, 15 kV), 230 km/h (15 kV, 25 kV). Length: 19.6 m. Service weight 87,000 kg. Wheel diameter 1.15 m.
