abstract

Alstom is the world's leading manufacturer of rail transit and energy equipment, and its controllers are widely used in train traction, signal system, power grid management and other fields. The following is a systematic summary of its core functions, technical features and typical applications:

I. Core functions

1. High-precision motion control

Traction and braking control:

Adjust the motor torque/speed in real time, support vector control (DTC/FOC), and the dynamic response time is less than 10ms.

Integrated electric braking regenerative braking, energy feedback efficiency of 85%.

Multi-motor cooperation:

Support multi-axis synchronous control of trains (such as load balancing of metro marshalling motors).

2. Safety monitoring and protection

Fault diagnosis:

Real-time monitoring of current, voltage, temperature and other parameters, triggering overcurrent/overvoltage/overheating protection.

Built-in SIL4 safety logic (EN 50129) ensures the reliability of train emergency braking.

Redundant architecture:

Double CPU lock step operation or two-out-of-three (2oo3) voting system, single point failure does not affect the operation.

3. Intelligent communication and integration

Multi-protocol support:

Vehicle networks: MVB(TCN standard) and Ethernet (IEEE 802.3).

Industrial bus: PROFIBUS DP, CANopen, Modbus RTU/TCP.

IIoT is ready:

Data is uploaded to Alstom HealthHub platform to realize predictive maintenance.

4. Human-computer interaction

Local operation interface:

Support touch screen or physical keys, parameter configuration/fault inquiry (such as MITRAC HMI).

Remote monitoring:

Connect the control center through GSM-R/5G, and transmit the running status in real time.

Growth by offering greater value to our customers

Alstom has strong market shares in all of its activities and geographies and we can now build on our ability to offer the best value proposition for its customers based on the most complete and a high performing portfolio in the industry, with Rolling Stock ranging from light rail to very high speed train, parts, maintenance and operations services, and a complete portfolio in Signalling.

Signalling and Services will continue to have the fastest growth potential. Alstom aims to be market leader in Signalling by 2025 benefiting from its technological leadership in ETCS, a presence in each strategic market and strong engineering hubs in mature and emerging markets.

In Services, Alstom targets to grow, leveraging on the widest installed base of the industry with, 150,000 vehicles, the most extensive depots network and 15,000 highly skilled service employees.

In Rolling Stock, Alstom comprehensive and best-in-class portfolio, continuously fuelled with innovation, is positioning the Group ahead of the game, and Alstom will focus most particularly on increasing competitiveness and profitability.

Innovation by pioneering smarter and greener mobility for All

Alstom has significantly reinforced his Research and Development (R&D) resources and intends to expand its leadership in rail innovation. With the new scale and combined expertise, the Group now has more than 9,400 patents and a unique scale and talent base in the industry.

The Group is the only railway company that provides all-round green traction solutions and internal fuel cell technology. Hydrogen trains have been running in Germany since 2018. The group has obtained firm contracts for 59 trains in Germany, France and Italy, and established various partnerships with other European countries. For smart mobile, the group's goal is to prepare fully automatic train prototypes for freight and passenger transport by 2023.

Alstom will also be able to leverage data from the 35,000 vehicles currently maintained and can count on its 7,500 software engineers and systems architects working on digital mobility solutions to further advance its offering to enable fully connected metros, trams as well regional trains.

Efficiency at scale, powered by digital

The continued transformation and efficiency gains combined with the successful integration of Bombardier Transportation will be a key focus to deliver on the Group’s ambitious profitable growth targets. The Group will continue to deploy its proven ability in operational excellence and project management, leverage its balanced global footprint, drive the digitalization of its value chain to optimise sites and projects and transfer its expertise throughout the new organisation.

One Alstom Team: Agile, Inclusive and Responsible

The Group reiterates its Corporate Social Responsibility convictions to aim for carbon neutrality in transport and increase social equity and inclusion by increasing the availability and efficiency of public transport. These convictions are driven by one Alstom team with one set of values: Agile, Inclusive and Responsible.

We have further extended its ESG 2025 targets and will bring this to the scope of the new organisation. Its priorities are: Enabling decarbonisation of mobility, Caring for our people, Creating a positive impact on society and Acting as a responsible business partner.
