The EuroSprinter family of electric locomotives is a modular concept of locomotives for the European market built by Siemens Mobility. 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 systems[1] commonly used in Europe).

Development

[edit]
Locomotive of Class 127 in Ingolstadt

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. The external appearance was similar to the earlier Siemens/Krauss-Maffei made dual voltage Spanish RENFE Class 252, delivered in 1991, which in turn used three phase asynchronous drive technology introduced with the DB Class 120.[2][3] The prototype was used for extensive tests in some countries in Europe (Norway, Spain, Portugal, Germany).[citation needed] The prototype was given the DB reporting name Class 127. It is still[when?] in service with Dispolok,[citation needed] a formerly Siemens-owned locomotive pool for on-hire use.

Standard types

[edit]

ES 64 F

[edit]
DB AG Class 152

The ES 64 F is an electric freight locomotive with 6,400 kW (8,600 hp) power and a top speed of 140 km/h (87 mph). 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 DB Schenker Rail. 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 decided that the track forces generated as a result of using nose-suspended traction motors exceeded standards and refused to certify them for use in Austria. Instead, DB AG changed the remaining 25 locomotives to Siemens model ES 64 U2 which were assigned as Class 182.

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 engine drivers argue that in autumn, due to greater power and lighter weight, especially with slippery tracks, heavy trains are hard to accelerate.

ES 64 F4

[edit]
DB AG Class 189

The ES 64 F4 is an electric freight locomotive with 6,400 kW (8,600 hp) power and a top speed of 140 km/h (87 mph), 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 (15 and 25 kV AC, 1.5 and 3 kV DC). 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 utilized by SBB as Class Re 474 and in service with PKP as class EU45. Some units are available to let from the Dispolok locomotive pool.

ES 64 U (Taurus)

[edit]
DB AG Class 182
PKP Intercity Class EU44

Based on the Eurosprinter concept the ES 64 U was developed as a universal electric locomotive with a top speed of 230 km/h (140 mph). The series ES 64 U is only capable of operating on the 15 kV 16.7 Hz AC supply. It is in service in Austria with ÖBB as Class 1016. Unlike the F series, all U series are equipped with quill drive instead, thus reducing the track forces.[4] The ÖBB assigned the protected name Taurus to Class 1016 (and later to the Classes 1116 and 1216); since then all ES 64 U+ series are widely known as 'Taurus' locos.

The ES 64 U2 can also operate on 25 kV 50 Hz AC. It is operated by ÖBB as Class 1116, by Deutsche Bahn AG as Class 182 and as well as by MÁV as Class 470 and as a hire locomotive from Dispolok. The Hungarian-Austrian company GySEV (Győr-Sopron-Ebenfurth Railway Corp) operates these units as Class 1047.

All four European electric systems 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 1216, in Slovenia by Slovenske železnice (SŽ) as Class 541 and in Poland by PKP Intercity (PKP IC) as Class EU44 "Husarz". In Italy RFI assigns it the classification E 190.[5]

Start-up sound of the ES 64 U2 (Taurus) locomotive.

ES64 U and ES 64 U2 locomotives have become notable for the musical-sounding notes, said to resemble an alto saxophone, produced when a train is moving off. The sound comes from the traction converters (German: Stromrichter)[6] and its duration/speed is dependent on the selected acceleration. ES 64 U4 locomotives do not produce this sound.

A 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 dual supply and can only operate on the German 15 kV 16.7 Hz AC and the Czech 25 kV 50 Hz AC systems. Even though these locomotives are only equipped to operate under AC power supplies like the DB Class 182, they received a new class designation because they meet the revised EU Driver Protection Standards which required significant structural changes: these include the entrance doors, from one on each side nearer to the middle of the locomotive to two on each side directly into the locomotive cab.

On 2 September 2006 the locomotive 1216 025-5 (prior to delivery to ÖBB) set a new world record for conventional electric locomotives, when, during the trials near Nürnberg, it reached a top speed of 357 km/h (222 mph).[5] The locomotive was not modified for the record. Since then, this type has become the fastest locomotive in the world.

For the newly built crossing of the Danish straits (Great Belt Fixed Link) the Danske Statsbaner ordered 13 units of the Class EG 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 of 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. [9]

Since 2000, Korea Railroad Corporation (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 or 53 mph 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.

Amtrak Cities Sprinter (ACS-64)

[edit]
Amtrak ACS-64

The ACS-64 (Cities Sprinter) design is based on the EuroSprinter, but with substantial modifications to meet United States safety standards including crumple zones and an improved safety cage for the driver. It supports all three catenary voltages used in the northeast U.S. (Amtrak's 25 Hz Traction Power System, Amtrak's 60 Hz Traction Power System & Electrification of the New York, New Haven and Hartford Railroad), which is the only region with substantial intercity electrification.[11]

Developments

[edit]

In 2010 Siemens announced a successor design, named 'Vectron' incorporating design features of both the Eurosprinter, and Eurorunner locomotives, initially available only in an electric version. The Eurosprinter design is to be continued to be offered by Siemens as well in the short term.[12]

The EuroSprinter is a family of modular electric locomotives designed and manufactured by for the European rail market, featuring adaptable configurations for various voltage systems and operational needs in both freight and passenger services. Introduced in the as a versatile platform to meet diverse European requirements, the EuroSprinter platform emphasizes in components like bogies, traction systems, and control electronics to reduce costs and simplify maintenance across borders. In 1993, a from the family achieved a world for rotary-current locomotives at 310 kilometers per hour, highlighting its advanced engineering capabilities. Key variants include the ES64U2, a dual-voltage model (15 kV 16.7 Hz AC and 25 kV 50 Hz AC) developed for with a maximum power output of 6,400 kW and top speed of 230 km/h, and the ES64U4, tailored for Italian operations with similar power but a maximum speed of 160 km/h for freight. These locomotives have been widely adopted by operators such as , , and SNCB, with over 1,500 units ordered by 2010 and nearly 2,000 built worldwide for cross-border and national services. The platform's success led to adaptations beyond , including the ACS-64 model for in the United States, but it was eventually succeeded by ' Vectron series starting in 2010, which builds on EuroSprinter's modular principles with enhanced digital features and multi-system compatibility.

Development and History

Origins and Prototypes

In the early , Transportation Systems initiated the EuroSprinter project to address the growing need for standardized, multi-purpose electric locomotives across Europe's diverse rail networks, following the liberalization of the rail market and the push for interoperability. The modular design concept allowed for adaptable configurations to meet varying voltage systems and operational requirements while maintaining a common platform for cost efficiency and maintenance standardization. This approach built on prior developments, such as the three-phase propulsion technology proven in the Class 252 locomotives delivered starting in 1991. The project formally began in 1991, culminating in the unveiling of the first , designated ES 64 P (also known as Class 127 under reporting), in 1992. Constructed by in partnership with Krauss-Maffei, the served as a demonstrator targeted at major operators like , which was seeking replacements for aging fleets. From 1992 to 1996, the underwent extensive testing on several European networks, including those in , , , , and , to validate performance under real-world conditions such as varying gradients, speeds, and electrification standards. These trials covered load-haul simulations, , and assessments, accumulating thousands of kilometers to refine the . During these trials, the set a world for three-phase AC at 310 km/h in 1993. The ES 64 P prototype featured a 6,400 kW continuous power output, a four-axle for balanced traction and stability, and an initial single-system AC design optimized for 15 kV 16.7 Hz electrification prevalent in and neighboring countries. This configuration emphasized high for freight duties alongside passenger service capability, with demonstrated speeds up to 310 km/h during record-setting tests. To further validate the platform, leased the prototype through its Dispolok subsidiary, enabling early operational deployments with private operators and contributing to design iterations before series production. This leasing model facilitated hands-on feedback from revenue services, accelerating the transition to production variants.

Production Milestones

The production of the EuroSprinter family marked a significant shift from development to serial , beginning with the first major contract awarded in 1999 to by DB AG for 100 ES64F4 locomotives designated as class 189 for freight services across . Initial deliveries of these units commenced in , enabling multi-system operations on key international corridors. Primary assembly of EuroSprinter locomotives occurred at ' Munich-Allach facility, a dedicated production site spanning 24,500 square meters, while components were sourced from suppliers across , including electrical systems from plants in and mechanical parts from partners in and other countries. This distributed approach facilitated customization for different voltage systems and national requirements. By 2010, had produced over 1,000 EuroSprinter units in total, incorporating adaptations for multi-system compatibility such as 15/25 kV AC and 1.5/3 kV DC, which allowed seamless cross-border operations and contributed to the platform's widespread adoption by European operators. A pivotal milestone was the late 1990s introduction of the Taurus variant (ES64U2) for , with the initial order of 75 units delivered starting in 2000, designed for high-speed passenger and freight duties up to 230 km/h on Austrian and neighboring networks. The Dispolok leasing fleet, operated by , saw substantial expansion in 2005 through additional orders for ES64F4 locomotives, including 50 units that enhanced availability for private rail operators and boosted the family's in the mid-2000s.

Design and Technical Features

Electrical and Propulsion Systems

The EuroSprinter's propulsion system centers on a robust electrical delivering a continuous power output of 6,400 kW, achieved through four three-phase asynchronous AC motors—one per axle in the Bo'Bo' configuration. This setup ensures even torque distribution across the axles, supporting high starting efforts and sustained performance across diverse operational demands. The asynchronous motors operate on , offering advantages in simplicity, low maintenance, and overload capacity compared to earlier DC systems. Traction electronics are powered by -based voltage source inverters in later variants, with earlier models using gate turn-off (GTO) thyristors; these provide precise variable frequency control to the motors. These inverters convert the fixed-frequency supply into adjustable AC waveforms, enabling smooth acceleration profiles and efficient speed regulation up to 230 km/h. The IGBT technology minimizes switching losses and harmonic emissions, enhancing overall system reliability and compatibility with modern signaling infrastructures. The interfaces with the overhead via one to four arrangements, depending on the number of voltage systems supported, including 15 kV 16.7 Hz and 25 kV 50 Hz AC, as well as 1.5 kV and 3 kV DC in multi-voltage variants. These incorporate aerodynamic designs and dynamic adjustment mechanisms to maintain optimal contact pressure and reduce arcing at high speeds. This configuration supports seamless cross-border operations without reconfiguration. Regenerative braking forms a core energy efficiency feature, recovering a significant portion of during deceleration by inverting motor operation to generate electricity fed back into the . This process, managed through the traction inverters, prioritizes electrical recovery over mechanical braking and aligns with environmental standards for . The system integrates with the bogie-mounted mechanical components for hybrid braking when regenerative capacity is limited.

Mechanical Construction and Controls

The EuroSprinter platform utilizes a modular body shell constructed from welded lightweight aluminum to achieve a balance of and reduced weight, enabling efficient operation under varying load conditions. Standard variants, such as the ES64F4, measure approximately 19.58 m in over buffers, with a Bo'Bo' distributing the locomotive's weight of 87 t evenly across four s at 21.75 t per . This design supports maximum speeds up to 140 km/h for the ES64F4 freight variant, while other models like the ES64U2 reach 230 km/h, all while adhering to European requirements. The bogies employ a conventional frame with nose-suspended traction motors flexibly mounted to minimize vibration transmission to the carbody, as seen in core platform designs. Primary suspension consists of coil springs and rubber elements on axlebox guides for smooth wheelset guidance, while secondary suspension uses flexicoil springs and yaw dampers to ensure stability during high-speed travel. Anti-hunt devices, including triangular tie rods and pivot connections, prevent lateral oscillations, contributing to reliable curve negotiation and reduced wear on components. The low-mounted bogie centers, spaced about 2.8-3 m apart per bogie, enhance the overall low center of gravity for improved rollover resistance. Onboard control systems are governed by ' SIBAS 32 architecture, which provides integrated management of traction, braking, and auxiliary functions through a robust (TCN) backbone for real-time data sharing. Later production builds incorporate (ETCS) Level 1 or 2 compatibility, enabling automatic speed supervision and interoperability across borders. Driver cabs feature ergonomic layouts with multifunctional desks, large windshields for visibility, and configurable multi-language displays and voice announcements to support operators from diverse regions. Safety enhancements include compliance with EN 15227 crashworthiness requirements via deformable front-end structures for energy absorption in collisions, alongside integrated automatic train protection (ATP) interfaces for braking and prevention.

Standard Variants

ES 64 F

The ES 64 F represents the original freight-optimized variant of the EuroSprinter family, designed specifically for heavy-haul operations on single-voltage networks. Equipped solely for 15 kV 16.7 Hz AC electrification, it is tailored for the German and Austrian rail systems, where it delivers reliable performance in demanding freight corridors. With a maximum speed of 140 km/h, the locomotive prioritizes and load capacity over high-speed capabilities, making it ideal for hauling block trains of bulk goods such as , , and intermodal containers. Production of the ES 64 F occurred between 1996 and 2001, with , in collaboration with Krauss-Maffei as , delivering a total of 170 units primarily to AG for use as Class 152 under . These locomotives formed the backbone of 's heavy freight fleet, replacing older six-axle models like the Class 150, while a small number were acquired by private operators, including two units sold to ITL Eisenbahngesellschaft. The design emphasizes durability and efficiency, sharing the core EuroSprinter platform with other variants but incorporating freight-specific reinforcements. Key adaptations for freight service include a reinforced frame supporting an of 21.7 tonnes, enabling it to handle payloads up to 5,000 tonnes on suitable routes. The locomotive's power output reaches 6,400 kW at the wheelset, provided by four nose-suspended asynchronous traction motors, which optimize and starting for steep gradients and heavy formations common in block train operations. Optimized for continuous heavy-haul duties, the ES 64 F features a robust underframe-mounted and GTO-based , ensuring high availability in intensive freight networks across .

ES 64 F4

The ES 64 F4 is a multi-system designed specifically for heavy freight operations, capable of operating on four systems prevalent in : 15 kV 16.7 Hz and 25 kV 50 Hz AC, as well as 1.5 kV and 3 kV DC. This versatility allows seamless cross-border hauls without changes, addressing the fragmented standards across , , , , and neighboring networks. With a maximum speed of 140 km/h and a power output of 6,400 kW under AC conditions (reduced to 6,000 kW at 3 kV DC and 4,200 kW at 1.5 kV DC), it prioritizes for demanding freight duties over high-speed travel. Production of the ES 64 F4 began in the early following orders placed in 1999, with over 100 units built by primarily between 2003 and 2005 at their facility. AG acquired more than 100 for use as Class 189, forming the backbone of their cross-border freight fleet, while Dispolok (later MRCE) ordered 45 units for leasing to various operators. Additional batches included 18 units for as Class Re 474 and smaller lots for private firms, totaling over 140 locomotives in service by late 2005 across operators like Railion Deutschland and SBB Cargo. The design draws from the earlier ES 64 F but incorporates modular upgrades for broader compatibility, with homologation achieved in nine European countries by 2006, including , , , , , , , and . To achieve DC compatibility within the locomotive's constrained body length of 19.58 m, the ES 64 F4 employs specialized adaptations, including dedicated line-voltage transformers integrated into the 3 kV equipment rack, alongside the primary AC transformers. This setup, combined with water-cooled IGBT-based traction converters using 6.5 kV modules, enables efficient power conversion without additional step-down choppers for DC modes, while supporting up to 2,600 kW (supplemented by rheostatic braking on DC lines). The Bo'Bo' and 87-tonne adhesion weight deliver a starting of 300 kN, suitable for hauling loads up to 6,000 tonnes, such as or trains. In operational deployment, the ES 64 F4 plays a central role in the Trans-European Freight Network, facilitating efficient intermodal and transport across electrified corridors. Examples include its use by leasing firms like MRCE Dispolok for services linking ports to inland hubs, as seen in operations supporting Eurogate's terminal networks in and with ISO trains. Its multi-system capability minimizes downtime at borders, enhancing reliability for operators hauling heavy freight on routes like the or through the .

ES 64 U (Taurus)

The ES 64 U, known as the Taurus, represents the universal high-speed variant of the EuroSprinter family, designed for passenger and mixed-traffic operations with optimizations for efficiency and cross-border compatibility. Developed by , it supports multi-system electrification, accommodating up to four voltages including 15 kV 16.7 Hz AC, 25 kV 50 Hz AC, 3 kV DC, and 1.5 kV DC (with power limited to 4,200 kW on the latter), allowing uninterrupted travel across varied European networks without changes. The achieves a maximum operational speed of 230 km/h, making it suitable for services while maintaining versatility for lighter freight duties. The "Taurus" nickname originated with the (ÖBB) for their Classes 1016 (single-system 15 kV AC) and 1116 (dual-system AC), reflecting its robust, bull-like performance in demanding terrains. Production of the ES 64 U commenced in 1998 for single-system variants, with a total of 437 ES 64 U2 units built from 1999 to 2006 and 129 ES 64 U4 units from 2005 to 2011. Key fleets include the ÖBB's extensive Taurus series (382 units across Classes 1016, 1116, and 1216), alongside adaptations for other operators such as Polish PKP Intercity's 10 ES 64 U4 units branded as EU44 "Husarz" (built 2008–2009) and Hungarian MÁV's Class 470 series of ES 64 U2 locomotives (10 units introduced from 2002). These units feature a modular platform enabling quick customization for national safety systems and signaling. Adaptations for high-speed passenger service emphasize and thermal management, including a streamlined cab with contoured roof elements to minimize drag and noise at elevated velocities. Enhanced cooling systems, incorporating advanced water-cooled traction converters and individual drives, ensure sustained power delivery of 6,400 kW even under prolonged high-load conditions, supporting reliable performance on inclines and in varying climates. These features draw from the base EuroSprinter mechanical frame but prioritize passenger comfort through reduced vibration and improved energy efficiency. The variant's capabilities were demonstrated in a world set on , 2006, when an Class 1216 ES 64 U4 (prototype later numbered 1216 050) achieved 357 km/h during trials on the Nuremberg-Ingolstadt high-speed line in , surpassing previous locomotive-hauled benchmarks and validating its high-speed potential. This achievement, conducted with a test coach, highlighted the Taurus's aerodynamic and propulsion optimizations under real-world conditions.

Derivatives and Adaptations

European Derivatives

The European derivatives of the platform represent customized adaptations produced under or in collaboration with local manufacturers to meet specific national requirements across European networks, incorporating modifications such as voltage configurations, gauge adjustments, and integration of regional systems. These variants emphasize while addressing unique operational demands, such as cross-border freight and passenger services on varied schemes. Built outside ' primary production lines, they highlight the platform's for regional customization without altering core technologies. In , (CP) ordered 25 units of the Class 4700 (LE 4700), delivered between 2008 and 2009, designed as a dual-system compatible with Iberian standards including 25 kV 50 Hz AC and 3 kV DC, and adapted to the 1,668 mm Iberian gauge. Rated at 4,700 kW with a top speed of 140 km/h, these units were constructed under license, with the majority assembled locally by EMEF in collaboration with to support both passenger and freight duties on Portugal's network. The design features bogies optimized for the wider gauge and enhanced adhesion for hilly terrain, distinguishing it from standard UIC gauge variants. Belgium's Société Nationale des Chemins de fer Belges (SNCB) acquired 120 units of the Class 18 (HLE 18 or ES60U3), produced from 2009 to 2012, tailored for DC-dominant operations with compatibility for 3 kV DC and 25 kV 50 Hz AC, incorporating ETCS Level 2 for advanced train control and a maximum speed of 200 km/h. These 88-tonne locomotives, with a power output of 6,000 kW, utilize a dual-pantograph setup and optimized for 3 kV networks, enabling efficient cross-border services into and other neighbors. Local integrations included adaptations for Belgian signaling and cab ergonomics to comply with national safety regulations.

Incidents and Safety Record

Notable Accidents

The EuroSprinter family has been involved in several notable accidents, though its overall record remains strong due to built-in redundancies such as multiple braking systems and advanced train protection (ATP) features. One significant incident occurred on February 6, 2007, near Szőny, , where an Taurus (ES64U2 class 1116 017) hauling a rear-ended a slowly moving after a signaling system failure. The collision happened at approximately 101 km/h following the driver's decision to switch to shunting mode and bypass a speed restriction, resulting in the death of the passenger train driver and injuries to several passengers from sudden deceleration forces. Investigations attributed the cause to a combination of signal malfunction due to issues and human override of interlocks, prompting reviews of cross-border signaling protocols in the region. Another major derailment took place on June 16, 2010, at Braz, Austria, involving Taurus locomotive 1116 173-4 pulling a loaded with new automobiles down a steep incline on the line. A detached cable struck stacked rails, kinking the brake hose and leading to the failure of the air system on multiple wagons, causing the train to accelerate uncontrollably to over 100 km/h before derailing on a curve. The locomotive overturned, and multiple wagons derailed, spilling dozens of across the tracks, but only the driver sustained a serious injury. The accident highlighted vulnerabilities in freight maintenance on mountainous routes, leading to enhanced inspection protocols for and dynamic testing across European networks. On February 28, 2023, a occurred in the Tempi Valley, , between an passenger train hauled by Class 120 locomotive 120-023 and a pulled by two Class 120 locomotives (120-012 and 120-022), both part of the EuroSprinter family (Hellas Sprinter variant). The accident, caused by where both trains were routed onto the same track due to dispatcher mistakes and lack of adequate signaling, resulted in the of multiple carriages and a . It claimed 57 lives and injured over 80 people, marking Greece's deadliest rail disaster. Investigations revealed systemic issues including poor maintenance, inadequate training, and absence of the (ETCS), leading to widespread reforms, including ETCS rollout on the line by 2024 and criminal proceedings against rail officials.
