ČD Class 680 are high-speed EMUs operating in the Czech Republic, using tilting Pendolino technology intended for the SuperCity train service. Built by Alstom (originally Fiat Ferroviaria), they were largely based on the nine-car ETR 470. While testing from Břeclav to Brno on November 18, 2004, the Pendolino reached a speed of 237 km/h (147 mph) and created a new Czech railway speed record.[1] The units are able to operate on 25 kV 50 Hz AC, 15 kV  16.7 Hz AC and 3,000 V DC.

History

[edit]

The initial Czech order for tilting trains was placed with Fiat Ferroviaria during 2000.[citation needed] As part of the Alstom take over of Fiat Ferroviaria the order was changed to Pendolino trains.[citation needed] The first set was delivered in 2004 as Pendolino ČD 680.

During the testing period, the train had problems with the Czech signaling system. The problems were reported to have been solved and the trains entered regular service in December 2005 between Prague and Ostrava. As of late January 2006, all five of the in-service trains suffered from software and operating problems, ranging from failing air conditioning and heating to malfunctions of the tilt controls. The supposedly ERTMS-compliant ATLAS control system is unable to properly connect several discrete systems, each based on different software platforms. Similar problems have also been reported with the Finnish VR Class Sm3. All problems were fixed.[citation needed]

Formation

[edit]

The seven car units are composed as:

Class Nº Type Class
681 Driving Motor 2nd
081 Trailer 1st
683 Motor Buffet 2nd
084 Trailer 2nd
684 Motor 2nd
082 Trailer 2nd
682 Driving Motor 2nd

Cars are individually numbered, with the driving motors carrying their numbers on the nose.

Operations

[edit]

Pendolino is used primarily for the SuperCity train service, which is the fastest train service of ČD.

In December 2006 Czech Pendolinos were given permission to operate in Slovakia and Austria.[citation needed]

In 2009 and 2011, one pair of ČD 680s operated as SuperCity Slovenská strela between Prague and Bratislava. However, it was cancelled due to a low demand, since the train was not actually faster, but more expensive.[citation needed]

As of 2020 ČD Pendolinos operated nine trips a day in each direction on the SuperCity train service under the name SuperCity Pendolino which is running the Prague-Pardubice-Olomouc-Ostrava route, with some continuing to Bohumín and one continuing to the Slovak city of Košice under the name SuperCity Pendolino Košičan. Twice a day the service is as extended as an InterCity train from Prague to Františkovy Lázně via Plzeň.[2]

Accidents

[edit]
  • On December 1, 2007 a Pendolino derailed in Prague. No one was injured but the train was severely damaged.[3]
  • On July 22, 2015 train SC 512 en route from Bohumín to Františkovy Lázně collided with a truck carrying sheet metal at a railway crossing in Studénka. Three passengers died and 17 people were injured. The unit 680 003 was badly damaged, the body of the driving car 682 had to be made new. The damage was over 200 million CZK, the unit returned to service in September 2018.[4]

  • On June 27, 2022 a Pendolino en route from Bohumín to Prague head-on collided with ČD Class 742 locomotive near Bohumín train station. According to police, Pendolino driver was drunk and drove through Stop signal. Pendolino driver died and 5 people were injured. It was initially intended that the damaged unit 680 006 would not be repaired and would be used for spare parts. Later it was decided that the two most damaged cars would be scrapped and the remaining ones would be repaired and fitted with ETCS and used as spare cars during repairs of other units.[5][6]
  • On March 1, 2023 a Pendolino en route from Prague to Košice derailed in Žilina. The train derailed because of railroad switch failure. No one was injured.[7]

ČD Class 680

View on Grokipedia
from Grokipedia
The ČD Class 680 is a class of high-speed tilting electric multiple units (EMUs) operated by České dráhy, the national railway of the Czech Republic, primarily on its premium SuperCity (SC) intercity services.[1] These trains employ Pendolino tilting technology to maintain passenger comfort at elevated speeds on curved tracks, with a maximum design speed of 230 km/h and recent operational speeds reaching 200 km/h in regular service.[2][3] Seven seven-car trainsets, each accommodating 331 passengers in a 2+1 seating configuration across first and second class, were constructed by Alstom (formerly Fiat Ferroviaria) at its Savigliano plant in Italy between 2003 and 2005.[2][4] Based on the Italian ETR 470 Pendolino design, the Class 680 units feature modern amenities including air-conditioning, Wi-Fi, power outlets, and a bistro car, making them suitable for long-distance routes such as Prague–Ostrava, Prague–Košice, and Prague–České Budějovice.[5][1] The fleet entered revenue service in 2004 following testing that achieved a Czech rail speed record of 237 km/h, though full regular operations commenced in December 2005 on the Prague–Ostrava corridor after resolving initial electromagnetic compatibility issues.[6][7] Since then, the Class 680 has become a flagship of Czech rail travel, with ongoing refurbishments since 2017 modernizing interiors, reducing energy consumption, and integrating the European Train Control System (ETCS) for enhanced safety and cross-border compatibility starting in 2025.[6][8]

Development and Design

Background and Ordering

In the mid-1990s, České dráhy (ČD), the national railway operator of the Czech Republic, sought to modernize its intercity services amid growing demands for faster and more comfortable travel on the country's predominantly curvy rail network. The initiative stemmed from a need to enhance speeds without extensive track reconstructions, drawing inspiration from the Italian Pendolino tilting train technology, particularly the ETR 460 series developed by Fiat Ferroviaria, with the Class 680 based on the ETR 470 design. This approach allowed trains to negotiate curves at higher speeds by actively tilting the car bodies, thereby reducing journey times on routes like Prague to Ostrava and international links to Vienna and beyond.[9] A public tender for 10 tilting electric multiple units (EMUs), designated as Class 680, was launched on June 7, 1995, and closed on August 7, 1995, with an initial estimated cost of 415 million CZK per unit. The contract was awarded to a consortium comprising Czech firms ČKD and MSV Metal Studénka, along with Siemens and Fiat Ferroviaria, aiming to produce domestically integrated trains based on Fiat's proven design. However, the consortium faced significant setbacks, including the bankruptcy of ČKD in January 2000, leading Fiat Ferroviaria to assume full responsibility for delivery in January 2000 under Clause No. 6 of the agreement. Subsequently, Alstom acquired a majority stake in Fiat Ferroviaria in October 2000, inheriting the project and reconfiguring it as the Pendolino series, ultimately reducing the order to seven 7-car sets to manage escalating costs and delays.[9][10][11] The revised contract, valued at approximately 3.5 billion CZK for Alstom's portion within a total of 4.2 billion CZK, specified delivery starting in 2004 from Alstom Ferroviaria's facilities in Savigliano, Italy. These units were designed with multi-system electrification to operate across the Czech (25 kV 50 Hz AC and 3 kV DC), Slovak, and Austrian (15 kV 16.7 Hz AC) networks, supporting ČD's SuperCity services and international interoperability. Early procurement challenges included financial underestimation, with unit costs rising from an original 415 million CZK to 750 million CZK due to redesigns, and difficulties in integrating the tilting mechanism with existing Czech signaling systems and infrastructure constraints, such as curve radii and axle load limits that necessitated adjustments.[12][9][10]

Construction and Technical Features

The ČD Class 680 Pendolino trains were constructed by Alstom Ferroviaria at its Savigliano plant in Italy, as part of a consortium that took over the project following the bankruptcy of original partner ČKD Dopravní systémy in 2000.[10] The first unit was completed in March 2003 and presented to representatives of České dráhy (ČD) on 26 March 2003, marking the start of production for the batch of seven triple-voltage tilting trainsets.[13] The initial unit arrived in the Czech Republic for testing on the night of 18-19 June 2003, with the remaining units delivered progressively and all seven completed by 2005.[14] Key design adaptations of the Class 680 incorporate Pendolino tilting technology, featuring an active hydraulic system that allows the carriage bodies to tilt up to 8 degrees to counteract centrifugal forces on curved tracks, thereby maintaining higher speeds of up to 230 km/h without compromising passenger comfort.[14] The aerodynamic nose design enhances high-speed stability and reduces air resistance, contributing to the train's overall efficiency on mixed electrification networks including 3 kV DC, 25 kV 50 Hz AC, and 15 kV 16.7 Hz AC systems.[13] Interior features emphasize comfort and accessibility, with a mix of first- and second-class seating arranged in a 2+1 configuration in second class for a total seated capacity of 327 passengers, including 52 first-class seats, two wheelchair-accessible spaces, and three areas for bicycles.[15] A dedicated bistro car provides onboard catering services, supporting the SuperCity service's focus on premium long-distance travel.[16] Safety systems integrated during construction include Automatic Train Protection (ATP) with dual units per trainset and a deadman's handle for driver vigilance, ensuring compliance with high-speed operational standards.[4] However, initial software issues in the control systems were noted prior to full delivery, which were subsequently resolved to improve reliability before entering passenger service.[14]

Specifications

Formation and Layout

The ČD Class 680 consists of a fixed seven-car formation designed for high-speed service, comprising four powered motor cars (M) and three unpowered trailer cars (T) to optimize weight distribution and performance. The specific arrangement is driving motor car 681 (1st class), trailer car 081 (2nd class), motor car 683 (2nd class with buffet), trailer car 084 (2nd class), motor car 684 (2nd class), trailer car 082 (2nd class), and driving motor car 682 (1st class). This configuration supports distributed traction across the powered cars, with transformer cars integrated into the trailers for electrical supply management. 1st class seating is located primarily in the front cars for quieter travel.[17][18] The trainset measures 185.3 meters in length over the couplers, 2.8 meters in width, and 4.31 meters in height (with pantographs lowered and in non-tilting position). Its service weight is 384 tonnes, providing a balanced load for stability during high-speed operations.[17][18] Internally, the layout emphasizes passenger comfort with open-plan saloons featuring a 2+1 seating arrangement in both classes. It offers 52 seats in 1st class and 275 seats in 2nd class, yielding a total of 327 seats, including 2 dedicated wheelchair-accessible spaces. The buffet facility in car 683 provides seating for 24 passengers and serves hot meals, snacks, and beverages. Luggage storage is integrated via overhead racks and end-of-car areas throughout the train, while 3 spaces are reserved for bicycles in designated zones.[15][17] As a multiple-unit electric trainset, the ČD Class 680 operates bi-directionally with driving cabs at both ends, eliminating the need for separate locomotives or turning facilities.[15]

Propulsion and Tilting System

The ČD Class 680 is equipped with a multi-system electric propulsion setup, enabling operation across diverse electrification networks in Central Europe. It draws power from 25 kV 50 Hz AC overhead lines on principal Czech main lines, 15 kV 16.7 Hz AC systems in Slovakia and Austria, and 3 kV DC on legacy Czech routes. This configuration supports uninterrupted cross-border travel without requiring power car exchanges. The train's traction is driven by eight asynchronous electric motors providing a combined output of 4,000 kW under optimal conditions.[14] The propulsion system incorporates phase-fired thyristor control for efficient power management and includes regenerative braking capabilities, which convert kinetic energy during deceleration back into electrical energy for reuse, enhancing overall operational efficiency. Performance characteristics include a design top speed of 230 km/h and an operational maximum of 200 km/h on approved lines as of September 2025, with acceleration reaching 0.4 m/s² to facilitate rapid starts in urban sections. These metrics, combined with the train's lightweight aluminum body construction, contribute to low energy consumption per passenger-kilometer, making it suitable for high-demand intercity services.[19][20] The tilting system features hydropneumatic actuators that enable up to an 8-degree body lean into curves, controlled by gyroscopes and accelerometers to detect track geometry and lateral forces in real time. This active mechanism permits speeds approximately 30% higher on curved sections compared to conventional non-tilting trains, reducing journey times while maintaining passenger comfort by countering centrifugal forces. The integration of this tilting functionality with the propulsion controls ensures smooth transitions and adherence to Automatic Train Protection (ATP) limits for safe high-speed navigation.[21][22]

Operational History

Introduction and Testing

The ČD Class 680 Pendolino, a high-speed tilting electric multiple unit, underwent extensive pre-service testing beginning in 2004 following its delivery from Alstom. Dynamic trials commenced that year, encompassing runs on Czech tracks and extending to multi-country routes to evaluate performance across varied infrastructure and signaling systems. A notable achievement occurred during these tests on November 18, 2004, when the trainset attained a speed of 237 km/h between Břeclav and Brno, establishing a new Czech railway speed record on conventional lines.[23] Certification for operational use proved challenging, with initial trials revealing compatibility issues between the train's systems and Czech signaling, including the Automatic Train Protection (ATP) and tilt control mechanisms. Software modifications were implemented to address these concerns, leading to approval by Czech authorities for operations at up to 160 km/h in 2006. By late 2006, the resolved issues enabled reliable high-speed performance, marking the transition from testing to full revenue service.[24] The Class 680 entered revenue operations with its first commercial run on December 11, 2005, along the Prague-Brno route, introducing tilting technology to everyday passenger services. This initial deployment was part of broader efforts to integrate the trains into the SuperCity network, with full incorporation achieved in June 2006 on the Prague-Ostrava line, enhancing connectivity between major industrial centers. Early operations faced hurdles, including delays stemming from necessary infrastructure upgrades to support high-speed tilting runs, such as track reinforcements and signaling enhancements on key corridors.[25][24]

Services and Routes

The ČD Class 680 primarily operates on SuperCity (SC) services, which are high-speed intercity trains requiring mandatory seat reservations and featuring first- and second-class accommodations along with an onboard buffet car. These trains provide the fastest connections along key corridors in the Czech Republic and extend into neighboring countries.[26] The core route runs between Prague and Ostrava, spanning approximately 356 km and taking about 3 hours, with services stopping only at major stations such as Pardubice and Olomouc. Extensions operate to Košice in Slovakia, facilitated by the train's multi-system electrical capabilities—25 kV 50 Hz AC for Czech and Slovak lines—along with coordinated international timetables. Since August 2025, additional SC services have been introduced to České Budějovice via the upgraded Prague–České Budějovice line, where the units achieve operational speeds up to 200 km/h; in September 2025, 200 km/h operations commenced on select sections. The Košice extension resumed full service in November 2025 following ETCS upgrades. As of November 2025, approximately 9 to 10 daily SC pairs serve these routes.[27][28][29][3][30][2] The fleet comprises seven Class 680 units, maintained at ČD's workshops in Prague-Ujezd to ensure high operational reliability.[31]

Incidents and Modernization

Major Incidents

On December 1, 2007, a ČD Class 680 Pendolino train en route from Prague to Ostrava derailed on the outskirts of Prague shortly before noon, with all seven cars leaving the tracks due to suspected sabotage.[32] No passengers or crew were injured, but the train sustained severe damage, particularly to its undercarriage, requiring it to be towed to a depot for assessment.[33] The most fatal incident involving the class occurred on July 22, 2015, when SuperCity train SC 512, a ČD Class 680 operating from Bohumín to Františkovy Lázně, collided with a truck at a level crossing in Studénka at approximately 7:43 a.m.[34] The truck driver, attempting to bypass a toll, became stuck on the tracks, leading to the impact that destroyed the front car and caused two passenger deaths from debris penetration, with 13 others injured to varying degrees.[35] The collision halted services on the major rail corridor and highlighted vulnerabilities at unguarded crossings.[36] Another serious event took place on June 27, 2022, when a ČD Class 680 Pendolino departing Bohumín for Prague collided head-on with a ČD Cargo Class 742 freight locomotive near Bohumín station in the early morning.[37] The crash resulted from the Pendolino driver's intoxication, killing the driver instantly and injuring five others, including four on the locomotive and one crew member on the Pendolino.[38] Unit 680.003 suffered extensive front-end damage estimated at CZK 280 million, leading to its partial scrapping for spare parts rather than full repair.[37] On March 1, 2023, a ČD Class 680 SuperCity train SC 241 from Prague to Košice derailed near Žilina station in Slovakia owing to a malfunctioning railroad switch.[39] The incident caused no injuries among the approximately 200 passengers, with only minor damage reported to the train and infrastructure, allowing services to resume after a brief disruption.[39] These incidents underscore recurring safety challenges for the ČD Class 680, including vulnerabilities at level crossings and issues with signaling or switch infrastructure, which prompted targeted safety reviews by Czech Railways and regional authorities.[37]

Upgrades and Future Developments

The modernization of the ČD Class 680 fleet has focused on equipping all seven units with the European Train Control System (ETCS) Level 2 to comply with mandatory requirements for exclusive ETCS operations on key Czech corridors starting in January 2025.[40] Installation began in 2023 through agreements between Alstom and ČD-Telematika, covering the full fleet.[40] The first unit, 680.001, underwent successful commissioning tests in February 2024 at Praha-Výstaviště, marking the initial integration of onboard ETCS components.[4] Each trainset features dual ETCS installations, including two European Vital Computers (EVCs) and upgrades to the Czech LS06 automatic train protection (ATP) system to accommodate the train's length.[4] As of November 2025, the entire fleet is fully equipped, enabling seamless operation on ETCS-equipped lines.[28] Other upgrades include post-accident repairs to maintain fleet availability. Following the 2015 Studénka level crossing collision, damaged cars from the involved unit (including 682.003 and 082.003) were repaired by Alstom in Savigliano, Italy, and returned to service in April 2018 after extensive structural work.[41] In the 2022 Bohumín collision, unit 680.003 sustained severe damage, leading ČD to repurpose its components for spares rather than full reconstruction, supporting ongoing maintenance of the remaining sets.[37] Interior enhancements, such as onboard Wi-Fi networks and additional USB charging ports alongside existing electrical sockets, have been progressively implemented across the fleet by 2025 to improve passenger amenities during long-distance services.[42] Future developments emphasize expanded operational capabilities and sustained service life. In August 2025, tilting operations were tested and introduced on the Prague–České Budějovice route, allowing select services to reach 200 km/h on upgraded sections like Soběslav–Doubí, reducing travel times by approximately one minute per run.[29] With ETCS Level 2 now standard, the system supports precise speed control up to 200 km/h, enhancing safety through continuous supervision and increasing line capacity and punctuality on modernized infrastructure.[40] The fleet's projected lifespan extends to around 2040 through routine maintenance, with no additional orders for new Class 680 units announced as ČD prioritizes other rolling stock acquisitions.[8]
