Posted on November 1, 2025

Siemens Mobility has officially broken new ground in rail automation with the launch of its Mireo autonomous electric train, a major step towards reshaping the future of rail transport. This innovation integrates the latest technologies, including the European Train Control System (ETCS), Automated Train Operation (ATO), and advanced obstacle detection sensors, making the Mirio Electric Train a pioneer in the next generation of automated railway systems. Autonomous capabilities promise to enhance safety, efficiency and sustainability, while significantly reducing operating costs. With this move, Siemens is not only developing Germany’s digital railway network, but also setting a new global standard for autonomous, environmentally friendly and cost-effective transportation, marking a pivotal moment in the evolution of rail travel around the world.

Siemens Mobility has made a major leap forward in transforming rail transport with the innovative improvement of its Mireo electric train. The latest version of this cutting-edge train includes advanced technologies aimed at achieving autonomous operations. Key innovations include the integration of the European Train Control System (ETCS), Automated Train Operation (ATO), and advanced obstacle detection sensors. These developments not only enhance system efficiency but also significantly improve safety standards and operational reliability.

This development represents a pivotal moment in the journey towards a smarter and more sustainable future for rail travel, making it more efficient, environmentally friendly and cost-effective.

Leading the way to autonomous rail travel

In 2023, Siemens Mobility began cooperation with Deutsche Bahn to develop the GoA4 autonomous train (automation grade 4) as part of the digitalization efforts of Germany’s rail network. The overarching goal is to automate every aspect of train operations, from initial setup to autonomous journeys between depots and station platforms. This represents a decisive step towards achieving full automation in rail transport, eliminating the need for human intervention during train operation.

The GoA4 system represents the highest level of automation, allowing the train to operate autonomously under the control of on-board systems. This eliminates the need for human operators while maintaining optimal safety, efficiency and reliability. The train’s advanced sensors, including smart cameras and LiDAR technology, enable it to detect obstacles, navigate the tracks and ensure smooth operation throughout its journey.

Real world testing and continuous development

The initial phase of testing of Siemens’ Mireo autonomous train was conducted at the Wegberg-Widenrath Test Center, a state-of-the-art facility designed to simulate real-world conditions. These early experiments allowed engineers to closely monitor the performance of autonomous train systems under controlled conditions. From now on, the testing will move to real-life railway scenarios, allowing Siemens to evaluate how the technology performs under actual operating conditions.

These tests are crucial to improving autonomous systems and ensuring their reliability in the fast-paced world of commercial railway operations. As the trials progress, Siemens intends to incorporate lessons learned to improve the train’s performance and improve its use in real-world service.

Unlock cost savings and enhance safety

One of the most compelling benefits of self-driving trains is the potential for significant cost reductions. With the automation of train operations, the need for on-board staff, such as conductors and drivers, has been greatly reduced. This transformation helps reduce labor costs while enabling more efficient use of resources. Furthermore, the ability to automate train scheduling and operations reduces delays, making services more accurate and efficient.

In addition to cost savings, integrating autonomous technology into railway systems will enhance safety. Through the use of intelligent sensors and on-board systems, autonomous trains can react faster and more accurately to their surroundings than human operators. This reduces the risk of accidents caused by human error and ensures safer and more reliable railway services for passengers and freight alike.

Furthermore, self-driving trains can improve energy consumption, which is a key aspect of sustainability. By adjusting speeds and operations in real time, these trains can reduce their environmental footprint and contribute to creating greener and more sustainable railway networks.

The role of the BR 430 train in the project

In addition to Siemens’ Mirio electric train, the project also includes the participation of the Bombardier BR 430 train, another major player in the development of autonomous rail transport. The collaboration between Siemens and Bombardier is a big step towards realizing the vision of fully autonomous trains. Together, they provide expertise in digital systems, sensor technologies, and rail automation, pushing the boundaries of what is possible in modern rail systems.

The results of this ambitious collaboration will be presented at the InnoTrans 2026 trade fair in Berlin. The event will highlight developments in the railway industry, in particular the ongoing development of self-driving trains, which promise to change the way railway networks operate around the world.

Siemens Mobility’s role in shaping the future of railways

Siemens Mobility’s work in developing autonomous rail transport underscores its continued leadership in the digitalization of the rail sector. The company has always been at the forefront of technological advancement in the transportation industry, and this project reinforces its commitment to innovation.

By developing automation in rail transport, Siemens is not only developing new technologies, it is also paving the way for a more sustainable, efficient and safer future of rail travel. Siemens Mobility’s developments lay the foundation for the widespread adoption of self-driving trains, which will redefine the rail industry and transportation sectors globally.

As testing continues and technology evolves, Siemens Mobility’s contributions to the future of autonomous rail transportation are shaping the future of transportation in ways that benefit passengers and operators alike. These advances in automation may be the key to creating a smarter, greener and more efficient railway network for generations to come.
