Railroads are receiving more and more attention as means for solving social issues such as global warming and concentration of populations in cities, with refurbishment of existing rail lines and construction of new rail lines underway in locations worldwide. Together with expansion of IoT technologies and digitalization, tasks to improve customer service that employ these technologies to increase railroad sector efficiency are also taking place. In addition to rolling stock and drive control devices, Hitachi is a systems integrator that can provide a full lineup of services that includes train drive control systems, power control systems and information services to support critical railway infrastructure.
As a global company, we are actively involved in railway projects in Europe, Asia and other locations outside Japan.
A total railway system integrator supporting the railway business with superior technologies and a proven track record.

Rolling Stock
@ Next generation Shinkansen train technologies
We are developing the next generation of Shinkansen trains while responding to transport needs such as faster rolling stock with increased accuracy in driving that applies diverse new technologies that are even more comfortable and environmentally friendly, with control of noise inside and outside rolling stock, controlled drive vibration, energy conservation, and smaller and more compact rolling stock that are easier to maintain.
A A-train (Hitachi's new processing technology and module-based production system developed in-house for rolling stock)
The "A" in "A-train" incorporates the meanings of the words "advance," "amenity," "ability," and "aluminum."
EUse of lightweight aluminum materials stabilizes costs during the life cycle, including maintenance and makes it easier to recycle and reuse materials.
EFriction stir welding (FSW), in which the welded surface is finished without any change in shape or color due to heat enables us to create beautiful outer surfaces.
EModule construction increases production efficiency and a flexible body structure that responds to a variety of needs.
B Environmentally friendly technologies (battery electric vehicle)
Battery electric vehicles can be driven on electric power from storage batteries in nonelectified sections, are environmentally friendly, reduce noise through an electrified drive system and improve passenger comfort.
Drive control devices
@ SiC inverter (SiC: Silion carbide)
Most rolling stock inverters utilize power devices made of silicon-based materials, but application of an inverter that uses SiC power devices that have a smaller device footprint, are lightweight and reduce power loss to further reduce energy use and improve performance to bring to life small rolling stock that are exceptionally environmentally friendly.
A Hybrid drive systems
We deployed hybrid drive systems to reduce environmental burden, lower fuel consumption of diesel railcars running in non-electrified sections and reduce carbon dioxide emissions. Energy during rolling stock acceleration and deceleration is stored in a lithium battery, which is reused as power from a supplemental power source and as energy during acceleration. Power generation is controlled as necessary based on acceleration of the rolling stock and the amount of energy stored in order to reduce noise when the rolling stock is stopped or coasting or when the driver stops the engine.
B Autonomous decentralized Train Integrated System (ATI)
Comprising the information network inside the rolling stock, the ATI controls drive control devices mounted to the rolling stock and brake devices, displays the device data and operating tire data based on turn signals mounted to the steering wheel, and controls service devices such as air conditioning and car interior LED displays and automatic announcement equipment. Automatic testing functions that link to self-diagnosis functions of the devices, and drive condition recording functions that record driving history are helpful when conducting maintenance and diagnosing malfunctions.
Safety devices and operation control systems
@ Digital ATC (Automatic Train Control Device)
ATC transmits position data of the train in front to trains in operation, and controls speed to ensure safe train operation. Digital ATC transmits the necessary limit position signal from the ground to the brake controller in order to stop, and the device on the vehicle automatically controls the distance from the lead train to ensure stable operation. Passenger comfort improves, making it possible to maintain shorter distance between trains and effectively increase the amount of transport possible.
A CBTC (Communication Based Train Control), ETCS (European Train Control System)
International standards for train signal systems include the CBTC for urban traffic such as suburban trains, subways and monorails, and the ETCS, for traffic between urban centers that can handle mutual entry between routes that cross national borders in Europe.
Hitachi became the first Japanese company to obtain the CBTC's highest level of safety certification from a European certifying institution and were the first Japanese company to successfully bring a vehicle-mounted signal device that conformed to the uniform signal system regulations of Europe (ETCS) to market in December 2013. We condensed our long record of rolling stock performance in Japan into a form that conforms to European standards.
B Operation Control Systems
This system monitors current train line conditions to control operation of trains on time. We are using the latest data processing and communication technology to develop drive organization systems to support speedy recovery when a train is delayed, and network functionality to connect distant stations. Monitoring control of power equipment and station facilities secures safe, stable transport, makes transport command operations more efficient and provides better passenger service.
Substation System
Railroad incoming and transforming systems require a system product that can achieve stable supply of power for safe, high-density transportation as well as incoming and transforming equipment for highly reliable railroad power that contributes to disaster prevention, environmental friendliness and energy conservation, yet does so with a small footprint.
In response to this need, Hitachi provides optimized railroad incoming and transforming systems that capitalize on our deep knowledge of railroad systems and IoT technologies.
Global Business Expansion
The world's railway market is forecast to continue growing. The Railway Business Unit views the demand for railway systems that supports social infrastructure in these countries around the world as a business opportunity to make an aggressive push into overseas markets. In 2015, we acquired the Italian railway vehicle systems manufacturer Ansaldo Breda (now the Hitachi Rail S.p.A.) and Ansaldo STS Company (now the Hitachi Rail STS S.p.A.) to have bases in Italy and other European countries as well as America and other regions. Doing so allows us to grow our product lineup to include better turnkey (bulk) solutions business ventures, a world-class product pool to enhance and expand our portfolio and enable us to focus more on IoT/ digital business, as we aim to further develop total solutions as a leading company in the railway system business. With a number of projects underway not only in Europe, but in the Americas, Asia and emerging nations, and other regions, a diverse team of human resources who can lead Hitachi's railway system business together with our global partners.
