The EuroSprinter family of electric locomotives is a modular concept of locomotives for the European market built by Siemens. The internal Siemens product name is ES 64 , with ES for EuroSprinter and the number 64 indicating the 6,400 kW power at rail.
Additional information is given in the name on the usage ( U as universal, P as prototype and F as freight) and on the number of electric power systems supported (e. g. 2 as two types, 4 as all four commonly used systems in Europe).
Development
The first prototype ES 64 P was built in 1992, as Deutsche Bahn AG was expected to issue a large order of locomotives as a replacement for the ageing Einheits-Elektrolokomotiven. Technically it was based on the Siemens-made Spanish RENFE Class 252, delivered in 1991. The prototype was used for extensive tests all over Europe. The prototype was given the DB reporting name Class 127 . It is still in service with Dispolok , a formerly Siemens-owned locomotive pool for on-hire use.
Standard types
ES 64 F
The ES 64 F is an electric freight locomotive with 6,400 kW power and a top speed of 140 km/h. Though it is equipped for passenger services, it is exclusively used for freight trains. It was introduced to Deutsche Bahn AG as class 152 in 1996 and today is operated by Railion. Its main role is to replace the older Class 150 and Class 151 locomotives on heavy freight trains. The original German order of 195 units was reduced to 170, as the ÖBB feared that the axle hung traction motors might affect the tracks on the country's mountain railway lines. Instead, DB AG ordered the remaining 25 ES 64 U2 .
It should be noted that with Class 152 DB AG abandoned the CoCo wheel arrangement of the class 150 and 151; with the new digitally controlled anti wheel-slip control the tractive effort should be brought to bear more reliably: nonetheless, some engineers argue that in autumn due to slippery tracks heavy trains are hard to accelerate. Maximum speed excluded, all performance characteristics are similar to those of DB AG class 101.
ES 64 F4
The ES 64 F4 is an electric freight locomotive with 6,400 kW power and a top speed of 140 km/h, in Germany the reporting name is Class 189. It is also equipped for passenger service, but seldom used in that role. ES 64 F4 is equipped for all four electric systems commonly used in Europe. Because limited space inhibits installation of all safety systems, Class 189 is equipped with various packages giving partial European coverage, e. g. Germany and Switzerland. The braking system includes an electrical energy recovery system.
As well as being in service with Deutsche Bahn AG as Class 189 it is also utillised by SBB as Class RE 474 . Some units are let from the Dispolok locomotive pool.
ES 64 U
Based on the Eurosprinter concept the ES 64 U was developed as a universal electric locomotive with a top speed of 230 km/h. The series ES 64 U is only capable to operate under 15 kV voltage. It is in service in Austria with ÖBB as Class Rh 1016 . Unlike the F series, all U series are equipped with quill drive instead, thus reducing the track forces. The ÖBB assigned the protected name Taurus to Class Rh 1016 (and later to the Classes Rh 1116 and Rh 1216); since then all ES 64 U+ series are widely known in as 'Taurus' locos.
The ES 64 U2 can also operate under 25 kV AC. It is operated by ÖBB as Class Rh 1116 , by Deutsche Bahn AG as Class 182 and as well as by MAV and as a hire locomotive from dispolok . The Hungarian company GySEV (Gyõr-Sopron-Ebenfurth Railway Corp) operate these units as Class 1047.
All four European electric systems (15 and 25 kV AC, 1.5 and 3 kV DC) can be used by the ES 64 U4 . Its electric components are mostly identical to those of ES 64 F4. The four-system series (with the 1500 V capability disabled within the software) are currently used in Austria by ÖBB and the private operator Rail Traction Service as Class Rh 1216 and in Slovenia by Slovenske železnice (SZ) as Class 541 . In Italy RFI assigns the classification E 190 .
The minor changes in the layout of this type means that it is the third generation of the Eurosprinter family.
A special version of the ES 64 U4 was delivered to the Vogtlandbahn of Germany with the designation Class 183 . Although the body is the same as any other ES 64 U4 locomotive, it is bi-current and can only operate on the German 15kV AC and the Czech 25kV AC system. This also reveals the first inconsistencies in the type designations, as it should be called a ES 64 U2, while Siemens only adopts the ES 64 U4 designation for this version; it is rumoured that the Vogtlandbahn locomotives do have the equipment to operate on all 4 systems (which could explain why Siemens remains with the ES 64 U4 designation), but that the different software used in this subseries and the lack of 2 extra pantographs prevents them from doing so.
On 2 September 2006 the locomotive Rh 1216 050-5 (prior to delivery to ÖBB) set a new world record for conventional electric locomotives, during the trials near Nürnberg it reached a top speed of 357 km/h . Remarkably enough, the locomotive was not modified for the record.
Derived types
Danish Class EG 3100
For the newly built crossing of the Danish straits (Great Belt Fixed Link) the Danske Statsbaner ordered 13 units of the Class EG 3100 which were delivered from 1999 to 2000. Based on the Eurosprinter concept, the wheel arrangement was modified to Co'Co' in order to ensure maximum tractive effort on the ramps. The tractive effort with this class is 400 kN (90,000 lbf) instead the usual 300 kN (67,000 lbf), with an overall length of 20.95 m (68 ft 9 in). This type is closest in design to a second generation ES 64 F2, capable of operating under 15 kV and 25 kV AC.
Greek Class 120
The Greek OSE Class 120 is their first electric locomotives in service. From 1996 to 2001 a total of 30 class 120 were delivered to Greece. The concept is mostly identical the ES 64 P prototype, with changes to the power (5,000 kW/6,700 hp) and the electric system (25 kV AC).
China Railways DJ1
In 1997, the Chinese Ministry of Railways ordered 20 units of type DJ1 freight locomotives from a joint venture formed by Siemens and Zhuzhou Electric Locomotive Works. These locomotives are based on second generation of EuroSprinter platform with modifications; the total number of axles were changed from 4 to 8 by permanently connecting two identical locomotives - as a result each sub-unit only has one drivers cabin. The first 3 of 20 DJ1s were built by Siemens in Austria, and the remaining 17 of 20 were built by Zhuzhou. All DJ1s were delivered between 2002 and 2003, and were put into Daqin Railway for hauling freight trains.
China Railways HXD1
Initially named DJ4, successor of DJ1, with more powerful traction motors, higher traction effort and IGBT traction inverters these locomotives were also intended for the Daqin Railway. The Chinese Ministry of Railways ordered 180 units of DJ4s from Zhuzhou and Siemens in 2004. All of DJ4s were built by Zhuzhou with technical support from Siemens. The first DJ4 locomotive was completed in 2006. Shortly after its delivery, the model name was changed from DJ4 to HXD1.
China Railways HXD1B
In August 18 , 2007 , Siemens and Zhuzhou won another contract from Ministry of Railways to build 500 Bo'Bo'Bo' EuroSprinter-based locomotives, at the time of production the locomotives are said to be the most powerful in the world in commercial production with a power of 9.6MW.
Korail 8100, 8200
Main article: Korail Class 8200Since 2000, Korail has continuously built ES64Fs to replace older class 8000 ELs. The Korail 8000 class electric locomotives are powerful but too slow (85 km/h maximum) to operate for general passenger train. Currently, 85 ES64F variants are built (2 of Class 8100 and 83 of Class 8200).
These new 8100s and 8200s are operating on major Korail lines, including Gyeongbu, Honam, and Jungang Line.
