Traila Active Steering technology for urban rail

At Traila, our ambition goes beyond a single solution; we are developing a suite of comprehensive Active Steering products and services that utilize sensor technology, advanced control automation systems, and state-of-the-art simulation analysis to create more efficient, robust, and safe rail transportation system designs.

Our technology expertise gained in the lab and in the field

To provide robust and reliable solutions for next generation rail vehicles, our engineers transcend traditional R&D boundaries by immersing themselves directly in the operational realities of the rail industry and bringing innovation directly to the tracks.

Sensors & Laser Scans

We are specialists in various sensor technologies, and our engineers develop new and interesting ways to apply advanced sensing for active steering postioning, track scanning and simulations improvement and validation.

HIL, SIL and Digital Twins

Our state-of-the-art Hardware and Software in the Loop (HIL & SIL) systems combined with digital twins provide an unparalleled testing and validation platform. These virtual replicas of our hardware enable us to optimize performance across countless situations before deployment. This accelerates development and ensures the highest precision and safety for our active steering systems.

Multi-Body Simulation, Vehicle Dynamics

Using the industry standard SIMPACK® we can predict how our system works, and ensure that our solutions work in a variety of vehicles and configurations.

Control System Development

Our control systems are built to interpret complex sensor inputs. Through rigorous testing and continuous improvement, we ensure our solutions are both innovative and practical for everyday use.”

Mechanical Design

Real world testing of simulated solutions is the only way to prove our systems work in all situations. Our engineers are experts in turning ideas and concepts into reality.

Field Testing

Field testing is crucial for validating our innovative active steering solutions. At Traila, we have a dedicated test tram, enabling us to conduct rigorous real-world trials. This hands-on approach allows us to refine our technology under actual operating conditions, ensuring reliability, efficiency, and safety.

Our development principles

Collaboration with partners in the field

By partnering with local operators, leading rail engineering consultants, and specialists in our niche areas of interest, we ensure that our solutions are deeply aligned with the operational realities and needs of the rail industry.

Safety at the core

Driven by a deep understanding of past challenges in active steering projects, we prioritize safety and rigorous testing protocols. Our strategy avoids over-complication by introducing innovation in a measured and agile manner, allowing us to better determine risk profiles.

Agile development

Using agile development methods, we combine rapid prototyping, control automation systems, and state-of-the-art simulation analysis. This approach allows us to iteratively refine our active steering solutions, respond quickly to new challenges, and continuously improve through feedback loops.

Developed with our partners in the field

We work with selected partners on the biggest challenges to solve system costs, curve speed and safety.

How it all comes together:

Here we can see how our multi-body simulation matches our tx4 tram during testing. We use our laser scan algorithms to improve our simulations environment and validate our sensor readings for our active steering development. As you can see, even in the curve, the flange does not touch the rail.

Our scientific papers

Traila is at the forefront of scientific innovation. Our achievements include groundbreaking proprietary algorithms that significantly improve the precision and efficiency of rail vehicle maneuverability, advances in control system theory, new approaches to rail simulation, tribology, machine learning, and artificial intelligence, as well as several patents for mechanical solutions in the rail industry.
