The ETR 460 is an electric multiple unit (EMU) tilting train produced by FIAT Ferroviaria (now Alstom Ferroviaria) since 1993. It is also known as the Pendolino after the family of trains from which it comes.

The ETR 460 is a development of the ETR 450, a Pendolino EMU developed in the 1970s, being characterized by improved layout, electrical and electronic systems, and improved comfort. Maximum speed remains unchanged at 250 km/h (155 mph). The ETR 460 spawned two similar types of Pendolinos: the ETR 470 and the ETR 480. The main difference between the versions is that the 460 runs only on 3 kV DC, the 470 on 3 kV DC and 15 kV AC, and the 480 on 3 kV DC and 25 kV AC (used on new high-speed railways in Italy). Three sets were modified to be capable of additionally running on 1.5 kV DC for use on Milan-Turin-Lyon services, but have been all re-converted to the ETR 460 standard and renamed ETR 463. The British Class 390, the Slovenian series 310, the Portuguese Alfa Pendular, the Finnish Sm3 and the Spanish Alaris series were all derived from the ETR 460.

The trainset, designed by Giorgetto Giugiaro, is used by Trenitalia for their Frecciabianca service on several routes across Italy.

The trainset has the ability to tilt by up to 8° when taking corners so as to reduce the effect of centrifugal force on the passengers. The passengers remain comfortable even if the train fully takes advantage of the characteristics of the track thanks to the lightness of the construction (only 13.5 t or 13.3 long tons or 14.9 short tons / axle). Use of the train does not demand particular modifications to the railroad but it is expensive in terms of maintenance of the rolling stock due to the complexity of the tilting system.

The hydraulic tilting system it is governed by two gyroscopes located in the lead cars. The curve is found on the base of the elevation of the external track.

ETR 460s are provided with 12 three-phase asynchronous motors (compared to the 16 in the ETR 450) located in all cars, in order to improve cornering capability. The motors are controlled by GTO-VVVF inverters, with a total power of some 6 MW. Electric braking is of rheostatic type, with the possibility of energy recovery at some speeds while the mechanical braking system uses disc brakes, commanded by an electro-pneumatic system called Wabcontrol.

ETR 460s can carry up to 480 passengers. Configuration includes two head coaches, 6 intermediate passenger coaches and a bar - restaurant coach.

FS Class ETR 460

View on Grokipedia
from Grokipedia
The FS Class ETR 460 is a nine-car (EMU) , known as the second-generation , manufactured by Ferroviaria (now ) for the Italian State Railways (, or FS) between 1993 and 1995, with a total of ten units produced exclusively for operation on Italy's 3,000 V DC electrified lines. Designed by Italian industrial designer as a successor to the earlier ETR 450, it features advanced tilting technology allowing up to 8 degrees of body lean on curves to maintain higher speeds on conventional tracks, achieving a maximum speed of 250 km/h while offering passenger capacity for up to 480 seats in a configuration of two powered end cars, six intermediate cars (four powered and two trailers), and one trailer end car. Introduced into service in 1993, the ETR 460 represented a significant advancement in Italy's capabilities, enabling 35% faster travel through curves compared to non-tilting trains due to its low of 13.5 tonnes and asynchronous AC motors delivering 6,000 kW of hourly power. The train's overall length measures 236 meters, with a total weight of approximately 440 tonnes, and it incorporates safety enhancements such as anti-tilting pistons and improved connections for enhanced passenger comfort and stability. Primarily deployed on FS's and Italia services along sinuous routes, the fleet underwent modernization starting in 2004 to extend its operational life. By late 2024, the ETR 460's service in Italy had concluded after three decades, with the remaining units being phased out and some dismantled, marking the end of this pioneering tilting train's role in Trenitalia's fleet as newer high-speed EMUs like the ETR 1000 took over. Despite its retirement from primary domestic duties, the ETR 460's innovative design influenced subsequent Pendolino variants, including the bi-voltage ETR 470 and the updated ETR 480, solidifying its legacy in advancing efficient, curve-negotiating rail travel across Europe.

Development

Background

The FS Class ETR 460 originated from the ETR 450 , Italy's first production developed in the 1970s and 1980s by FIAT Ferroviaria in collaboration with Ferrovie dello Stato (FS). The ETR 450, ordered in 1985 and entering service in 1988 on the Milan-Rome line, introduced active hydraulic tilting technology that allowed trains to lean into curves, enabling higher speeds of up to 250 km/h on conventional tracks without extensive infrastructure upgrades. This innovation reduced travel times by approximately 22% compared to non-tilting trains, demonstrating the potential of tilting mechanisms to enhance efficiency on Italy's curved rail network. By the early , the expanding demands of Italy's rail network, including growing passenger volumes and the need for further journey time reductions on non-high-speed lines, highlighted the limitations of first-generation tilting models like the ETR 450. These trains, while groundbreaking, faced challenges with maintenance of complex hydraulic systems and opportunities for improved passenger comfort and amid increasing service requirements. FS sought upgraded tilting trains to address these inefficiencies, aiming to achieve even greater speed gains on existing infrastructure while maintaining safety standards, such as limiting uncompensated lateral acceleration to 0.08g. In response, FS ordered 10 units of the ETR 460 in the early . The initial collaboration between FS and Ferroviaria, which had begun in the late 1960s with early tilting tests, intensified in the late 1980s to develop second-generation requirements. This partnership built on prototypes like the ETR 401, tested extensively from 1976 to the mid-1980s, covering over 600,000 km in revenue and high-speed trials to refine tilting control systems. These 1980s milestones, including the ETR 450's operational validation, provided critical data on curve negotiation and system reliability, directly informing the design specifications for the ETR 460 as a more advanced successor.

Design process

The design process for the FS Class ETR 460 began in 1989 through a between Ferroviaria and Giugiaro Design (part of Italdesign), focusing on exterior and interior styling for applications. This partnership built on prior developments, with Giugiaro Design contributing streamlined external aesthetics to reduce aerodynamic drag and innovative interior configurations to enhance passenger experience. The extended to the ETR 460 as part of Ferroviaria's progression from the ETR 450 model, emphasizing aesthetic and functional integration for operations. Key improvements over the ETR 450 included enhanced electrical and electronic systems for better reliability, optimized interior layouts to improve flow and comfort, and the integration of an advanced hydraulic tilting mechanism. These upgrades addressed limitations in the ETR 450's control systems and accommodations, allowing for smoother high-speed on curved tracks while maintaining a maximum operational speed of 250 km/h on conventional lines. The refined layout prioritized and space efficiency, drawing from extensive feedback on earlier models. Prototyping for the ETR 460 advanced in –1993, involving the development of conceptual designs with independent-wheel trucks and elements. This phase included testing to optimize and reduce train resistance by up to 40% compared to predecessors, alongside simulations for curve negotiation to validate stability at high speeds. These tests built on prior ETR 450 trials, incorporating real-world data from international routes to refine performance. A central was the of an active tilting system, controlled by onboard computers using from accelerometers and gyroscopes, enabling up to 8° of tilt via electro-hydraulic actuators. This computer-managed system sequenced tilting across cars to minimize lateral accelerations during curves, achieving cant deficiencies of up to 280 mm while ensuring comfort and limits (e.g., 0.08g lateral force). The design targeted enhanced curving performance on standard , positioning the ETR 460 as a successor to earlier Pendolinos.

Design

Structure and aerodynamics

The FS Class ETR 460 is configured as a nine-car (EMU), comprising two end power cars, six intermediate cars (including a restaurant car), and articulated joints between cars to enhance flexibility when navigating curves. This semi-articulated arrangement, with three independent traction modules each powering two motor cars and one trailer, distributes weight evenly while allowing smoother passage through bends without excessive track forces. The overall length reaches approximately 236 meters, with each car measuring 26.2 meters long and 2.83 meters wide, supporting a low of 13.5 tonnes to maintain stability on conventional infrastructure. The train's carbody employs a lightweight aluminum alloy structure, utilizing extruded sections and welded stressed-skin construction primarily from alloys such as AA-5083 for sides and bottom panels, providing high strength-to-weight ratio essential for high-speed operations. Designed by , the exterior features a streamlined that tapers sharply to minimize frontal drag and pressure waves, contributing to an overall aerodynamic profile optimized for reduced air resistance. This design, combined with smooth underbody panels and roof contours, achieves up to 40% lower aerodynamic resistance compared to non-streamlined predecessors, enabling at elevated speeds. Aerodynamic enhancements include strategic placement on the roof of non-tilting sections, equipped with aerodynamic fairings to streamline and prevent at high velocities. These features, along with side skirt fairings and gap seals between articulated joints, were rigorously tested in wind tunnels and on-track trials, confirming dynamic stability up to 250 km/h with minimal sensitivity. The body's 95% recyclability further underscores its modern material choices, balancing environmental considerations with performance. For structural integrity, the ETR 460 adheres to UIC 566 standards, incorporating -absorbing zones at the car ends with deformable crush structures and deep transverse girders capable of withstanding 2,000 kN compressive loads. These zones dissipate collision through controlled deformation, protecting the passenger compartment while integrating seamlessly with the tilting mechanism for overall safety.

Tilting system

The FS Class ETR 460 incorporates an active tilting featuring hydraulic actuators that enable the carbody to to 8° relative to the bogies. This mechanism operates independently for each car, with the actuators mounted under the floor to provide smooth, controlled movement during curve negotiation. The is governed by gyroscopes and accelerometers positioned in the lead cars, which detect lateral motion and track superelevation to initiate and adjust the tilt angle precisely. Upon entering a , the activates automatically to lean the carbody inward, directly counteracting centrifugal forces and maintaining stability without relying on track cant alone. This allows the train to achieve speeds approximately 30% higher than non-tilting equivalents on conventional legacy lines, eliminating the need for costly modifications such as increased superelevation or track realignment. The primary benefit lies in substantially lowering the lateral acceleration felt by passengers, limiting it to around 1.4 m/s² even at elevated speeds, which supports comfortable operation up to the 250 km/h service limit on curved routes. As a second-generation design, the ETR 460's tilting system requires specialized maintenance, including regular inspections and fluid replacements for the hydraulic components and calibration of the , which elevate overall upkeep demands compared to non-tilting trains.

Passenger accommodations

The FS Class ETR 460 features a nine-carriage configuration optimized for passenger comfort on high-speed routes, consisting of three first-class cars, five second-class cars, and one dedicated car. The first-class cars provide 137 reclining seats arranged in a 2+1 layout, offering wider spacing and enhanced legroom compared to second class, while the five second-class cars accommodate 341 seats in a 2+2 arrangement for efficient capacity. Additionally, two dedicated spaces for users are integrated into the layout, ensuring throughout the train. In the end cars, seats are designed to rotate for directional flexibility, allowing reconfiguration based on the train's operating direction without requiring turnaround maneuvers. The entire interior is fully air-conditioned, with dedicated luggage racks positioned near entrances and overhead for convenient storage, minimizing disruption to seated passengers. Onboard amenities include accessible toilets in multiple cars, power outlets available at each seat for charging devices, and courtesy lighting for reading and ambiance. The car serves as a with counter seating and tables for light meals and refreshments, complementing the overall focus on comfort. Noise insulation is achieved through and the train's tilting mechanism, which up to 8 degrees counters centrifugal forces on curves for a smoother, quieter ride. Total seated capacity is limited to passengers to optimize the tilting system's and prevent excessive load shifts during high-speed .

Technical specifications

Power and propulsion

The FS Class ETR 460 employs a distributed traction system powered by twelve three-phase asynchronous AC motors, one per powered axle, delivering a continuous power output of 5,880 kW (7,885 hp) and an hourly rating of 6,000 kW (8,046 hp) under the 3,000 V DC overhead catenary. These motors, manufactured by Alstom, are integrated across six of the nine cars to optimize weight distribution and enhance stability during high-speed operations up to 250 km/h. Propulsion control is managed through GTO (Gate Turn-Off) thyristor-based chopper-inverter units, which provide variable voltage variable frequency (VVVF) operation for precise torque regulation and smooth acceleration. This system converts the DC supply to AC for the motors, enabling efficient power delivery and reducing mechanical wear. is a key feature, where excess is converted back to electrical power and fed into the , recovering a significant portion to improve energy efficiency. The design incorporates Jacobs-style articulated bogies in the intermediate cars, which share axles between adjacent vehicles and facilitate the train's tilting mechanism without requiring speed reductions on curved tracks. This arrangement across the trainset ensures balanced propulsion and compatibility with the hydraulic tilting system for maintaining high speeds on conventional lines.

Dimensions and capacity

The FS Class ETR 460 measures 236 m in overall length, comprising nine cars designed for efficient operations on the Italian rail network. Its body width is 2.83 m, allowing compatibility with standard loading gauges while optimizing space for passengers. Weighing 440 tonnes when empty, the ETR 460 maintains an below 16 tonnes—specifically 13.5 tonnes per axle—to ensure compatibility with existing without necessitating extensive track upgrades. It operates on the standard gauge of 1,435 mm, the prevalent track width across the Italian State Railways (FS) system. These dimensions and weight characteristics enable the train to navigate conventional lines at high speeds while adhering to structural limits. In terms of passenger capacity, the ETR 460 accommodates 477 to 480 seats across its nine , including dedicated spaces for first-class, second-class, and a Frecciabistrò , plus provisions for two passengers with disabilities and their companions. This configuration supports high-density intercity travel, balancing comfort and throughput on routes like those served by services. Dedicated spaces enhance for users and those with reduced mobility, aligning with standards for inclusive rail design.

Production and introduction

Manufacturing

The FS Class ETR 460 trainsets were manufactured by FIAT Ferroviaria at its facility in Savigliano, , which later became part of following the company's acquisition in 2000. In response to an initial order placed by (FS) in 1992, FIAT Ferroviaria produced a total of 10 nine-car trainsets between 1993 and 1995. The first ETR 460 unit rolled out of the Savigliano factory on June 12, 1994, with all deliveries completed by early 1995 to enable revenue service commencement that May. Each trainset was assembled from a combination of six motor cars and three unpowered trailer cars, featuring aluminum double-skin bodyshells for lightweight construction and enhanced . The hydraulic tilting mechanisms, capable of up to 8 degrees of lean, were incorporated during the assembly phase to ensure seamless integration with the car's structural framework, followed by rigorous testing of the hydraulic components for reliability under high-speed conditions. This modular approach to carbody and systems integration allowed for efficient production while maintaining the series' focus on curve negotiation at speeds up to 250 km/h.

Entry into service

Following dynamic testing on the Milan-Bologna line, the FS Class ETR 460 received approval from Ferrovie dello Stato (FS) in 1994, verifying its capability to operate at speeds up to 250 km/h. The ETR 460 entered revenue passenger service in May 1995 on intercity routes, though initial operations were restricted to a maximum speed of 200 km/h to ensure system stability and passenger comfort. These early runs focused on major domestic corridors, allowing FS to monitor real-world performance before full-speed deployment. Based on feedback from trial operations, early adaptations included software updates to enhance tilting system reliability, addressing minor issues identified during testing, such as component wear in the transmission bearings. These refinements facilitated smoother integration into FS's existing schedules, with the assigned to peak services. The complete fleet of 10 units was fully operational by 1995, marketed under the brand to emphasize their innovative tilting technology and speed advantages over conventional . This rollout marked a significant step in FS's modernization efforts, enabling more efficient use of the national network without extensive infrastructure upgrades.

Operational history

Early operations

The FS Class ETR 460 entered in 1994, initially deployed on major intercity routes including to and to , where its active tilting system enabled higher speeds on existing conventional tracks without the need for extensive infrastructure upgrades. These trains were incorporated into Eurostar Italia's daytime network, which was later rebranded as , providing comfortable high-speed connections at operational speeds limited to 220 km/h despite a design capability of 250 km/h. The tilting technology, limited to an 8° angle for passenger comfort, allowed the ETR 460 to negotiate curves at up to 35% higher speeds than non-tilting , significantly shortening travel times on Italy's winding legacy lines. Early operations were marked by high utilization, reflecting intensive deployment to meet growing demand for faster rail travel. However, the saw initial reliability challenges, particularly with the electronic controls for the tilting system and curve detection, leading to occasional operational disruptions that were addressed through mid-2000s redesigns and improvements by manufacturers like Ferroviaria. The introduction of the ETR 460 contributed to economic benefits by reducing journey times on curvy routes, thereby enhancing rail's competitiveness against air and road travel and increasing ridership on intercity services.

Later years and routes

In the 2010s, the ETR 460 series achieved peak operational intensity as a core component of Trenitalia's Frecciabianca services, primarily on north-south Italian corridors such as Rome to Milan, Turin, and Genoa. These tilting trains were particularly valued on non-high-speed lines, where their design enabled faster travel times compared to conventional rolling stock by navigating curves at up to 35% higher speeds. The fleet's average service speeds ranged from 180 to 200 km/h, providing reliable connectivity across diverse terrains while avoiding direct competition from faster Frecciarossa sets on dedicated high-speed infrastructure. International operations expanded the ETR 460's role modestly, with three units temporarily modified to ETR 463 for 1.5 kV DC operation on cross-border Turin-Lyon routes in before being re-converted. Domestically, the Adriatic coast line from to exemplified the train's utility, where the tilting mechanism maximized efficiency on winding coastal tracks, supporting daily schedules that connected northern industrial hubs with southern ports. This route diversity underscored the ETR 460's adaptability in the later years, sustaining high passenger volumes until progressive phase-out pressures emerged. Adaptations during the decade focused on sustaining reliability amid aging infrastructure; units underwent modernization starting from , including enhancements to electrical and electronic systems, which carried into routine overhauls in the to maintain performance standards. By mid-decade, the fleet demonstrated robust , though escalating maintenance demands due to the trains' 20-plus years of service began to influence operational planning.

Retirement

The phase-out of the FS Class ETR 460 fleet began in late 2023, marking the end of nearly 30 years of service for these second-generation tilting trains. Introduced in 1994, the 10 units produced by FIAT Ferroviaria were progressively withdrawn due to their age, escalating maintenance requirements, and the need to replace them with more modern high-speed trains capable of better performance on upgraded lines. By November 2024, the operational life of the entire fleet had concluded, with the withdrawal coinciding with the discontinuation of Trenitalia's brand. One unit, ETR 460.029 ("Botticelli"), was lost following the derailment on January 12, 1997, where it partially derailed at the station entrance, resulting in eight fatalities and at least 29 injuries; the damaged train was subsequently partially demolished after investigations. Of the remaining nine units, six continued in active service on conventional lines until early 2024, while three had been stored or withdrawn earlier due to in their electronic systems and reduced efficiency on high-speed . The obsolescence of the ETR 460's original 3 kV DC-only electrical systems and tilting mechanisms made them unsuitable for full integration into Italy's expanding high-speed network, accelerating their replacement by bi-voltage and more advanced EMUs. Total retirement was completed by late 2024, with several units sent for dismantling and potential cannibalization for spare parts to support related variants still in use elsewhere.

Incidents

1997 Piacenza derailment

On January 12, 1997, at approximately 13:26, the ETR 460 Pendolino unit No. 29, named "Botticelli" and operating as Eurostar train 9415 from Milan Centrale to Rome Termini, derailed on the approach to Piacenza station in northern Italy. The nine-car train, carrying 167 passengers and crew, was traveling at 160 km/h through a left-hand curve immediately after crossing the Po River bridge, exceeding the 105 km/h speed limit for that section of the conventional Milan-Bologna line. The excessive speed caused the lead car to overturn and all cars to derail, resulting in extensive damage to the tracks and infrastructure near the station, about 400 meters from the passenger building. The claimed eight lives and injured 36 others, with fatalities including both drivers, two railway police officers (Polfer agents), two onboard hostesses, and two passengers, while the deceased included both drivers, two railway police officers (Polfer agents), and two onboard hostesses. Rescue operations involved local fire services and medical teams, who extracted survivors from the wreckage amid reports of passengers being thrown from their seats due to the sudden deceleration. Initial news coverage highlighted the dramatic scene, with luggage and scattered across the site, but the tilting mechanism of the ETR 460 functioned as designed during the , unable to fully compensate for the speed violation on the tight radius. An expert perizia (judicial ) submitted in mid-1997, based on analysis of the train's and data, attributed the primarily to driver error in maintaining excessive speed, compounded by a signaling anomaly: a mandatory speed reduction signal had been relocated 300 meters closer to the curve in 1992 to optimize , providing insufficient . No of mechanical failure, , or impairment (such as alcohol) was found among the crew, and 25 Ferrovie dello Stato executives were later acquitted of charges in 2001. The investigation underscored factors in the absence of advanced at the time. In the aftermath, the severely damaged ETR 460-29 was deemed uneconomical to repair and scrapped, marking the only such loss in the class. The incident triggered a parliamentary and nationwide audits by Ferrovie dello Stato, culminating in the accelerated rollout of the SCMT (Sistema di Controllo della Marcia del Treno) automatic train protection system across the fleet and conventional lines to enforce speed limits and trigger emergency braking for violations. These measures addressed vulnerabilities exposed by the signaling error and driver oversight, enhancing overall rail protocols in .

Safety record

The FS Class ETR 460 has demonstrated a low incident rate over more than 30 years of service, with one fatal accident recorded during its operational history. The train's active tilting mechanism, limited to 8° for enhanced stability, has significantly reduced risks on curved tracks by compensating for lateral forces, allowing safe operation at speeds up to 250 km/h on conventional lines without compromising track integrity or passenger safety. Following the 1997 , which involved one ETR 460 unit and resulted in 8 fatalities and 36 injuries, the entire fleet was temporarily suspended for safety assessments, leading to mandatory enhancements in the Automatic Train Protection (ATP) systems, regular inspections of the hydraulic tilting actuators, and updated crew training protocols to improve response to overspeed conditions on high-curvature sections. These measures ensured the fleet's safe return to service and addressed vulnerabilities in the original design related to signal override and performance. The ETR 460 fleet has exhibited reliability in demanding Italian rail networks. This performance contributed to the establishment of Italy's national standards for tilting , emphasizing fault-tolerant hydraulic systems and low loads (13.5 tonnes) for curve negotiation. In comparisons with non-tilting electric multiple units (EMUs) on similar routes, the ETR 460 exhibits superior due to its stability features, including reduced climb risks (L/V ratios below 0.5 at high cant deficiencies) and lower unsprung (1.5 tonnes per ), which minimize track wear and overturning potential during high-speed curving. These attributes have set benchmarks for subsequent Italian high-speed designs, promoting broader adoption of tilting technology while maintaining a focus on preventive maintenance and .

Variants

Italian variants

The ETR 470 represented an evolution of the ETR 460 designed specifically for cross-border operations, featuring dual-voltage capability for 3 kV DC and 15 kV 16⅔ Hz AC electrification systems to enable service on Italian and Swiss networks. Nine nine-car units were constructed by Ferroviaria between 1993 and 1997, incorporating minor upgrades to the electronic systems while maintaining the core 9-car formation for consistency with the base model. These trains supported speeds up to 200 km/h and a power output of approximately 6,000 kW, enhancing operational flexibility across electrified borders without the limitations of DC-only infrastructure. Some units were later transferred to in for service on the – line (as of 2025). The ETR 480 further advanced the series for domestic high-speed routes, introducing compatibility with 25 kV 50 Hz AC alongside 3 kV DC to access Italy's expanding AC-electrified lines. Fifteen nine-car sets were built by Ferroviaria starting in 1997, delivering an improved power output of 5,880 kW and a maximum speed of 250 km/h for efficient long-distance services, including those near international borders. This variant emphasized enhanced traction and braking performance to handle the demands of mixed-voltage networks. Both the ETR 470 and ETR 480 retained the hydraulic tilting system of the ETR 460, allowing up to 8 degrees of active body leaning to maintain passenger comfort on curved tracks, as well as the distinctive exterior styling by featuring aerodynamic nose cones and streamlined profiles. Across the ETR 460, 470, and 480 series, a total of 34 Italian second-generation units were produced, forming the backbone of operations for . Key differences from the DC-only ETR 460 included the variants' multi-voltage transformers and , optimized for 25 kV AC lines to extend operational range to high-speed corridors like those connecting major cities and extending toward neighboring countries. These enhancements allowed the ETR 470 and ETR 480 to operate seamlessly beyond traditional Italian DC networks, supporting broader integration into Europe's electrified rail systems.

International derivatives

The FS Class ETR 460's tilting technology and overall design principles were licensed and adapted for international use, marking the export of Italian innovation beyond domestic lines. In the , the , developed under a agreement following 's acquisition of Ferroviaria in 2000, was built for the . This derivative incorporated the ETR 460's hydraulic tilting mechanism, allowing up to 8° of tilt to navigate curves at higher speeds, with a maximum operational speed of 225 km/h. The initial fleet comprised 11 nine-car sets and 7 eleven-car sets, assembled by in Birmingham, enabling enhanced capacity and performance on upgraded infrastructure (fleet expanded and in service as of 2025). In Portugal, the Alfa Pendular trains for Comboios de Portugal (CP) represented a direct adaptation of the ETR 460 platform, ordered in 1996 from Fiat Ferroviaria for operation on the electrified network. These nine-car electric multiple units featured electric-hydraulic tilting systems derived from the Italian design, modified for Portugal's 25 kV AC overhead electrification, and achieved a top speed of 220 km/h on routes like Lisbon-Porto. A total of 10 units were delivered between 1998 and 2001, assembled locally by ADtranz in partnership with Fiat Ferroviaria, and remained in premium intercity service through the 2020s following mid-life refurbishments (9 units active as of 2025). The ETR 460's influence extended to other European operators through licensed technology sharing, particularly its hydraulic tilting principles that improved curve negotiation without extensive track upgrades. In , the Alaris series (classified as S-490) were built in the late as close derivatives of the ETR 460, with Ferroviaria supplying the core design for 10 tilting EMUs adapted for 3 kV DC systems, operating at up to km/h on regional high-speed services until their withdrawal in 2014, with six units reintroduced in 2022 for medium-distance services at up to 160 km/h (as of 2025). The ETR 460's exported expertise laid the groundwork for subsequent generations of trains, demonstrating the scalability of Italian tilting technology globally. This legacy is evident in third-generation models like the ETR 600, which built upon the ETR 460's aerodynamic and electronic advancements for international markets, further solidifying Fiat Ferroviaria's (later Alstom's) role in exports.
