As the railway sector undergoes rapid transformation, manufacturers must combine performance, reliability and innovation while securing their supply chains. In this demanding environment, choosing the right partners has become a strategic priority.
Against this backdrop, Crouzet will take part in InnoTrans 2026, the world’s leading international trade fair for transport technology. It will be an opportunity to showcase an approach built on five pillars: expertise in critical environments, a long-term commitment to rail, global manufacturing capabilities, broad application coverage, and technologies dedicated to the most demanding functions.
Crouzet: an expert in critical environments
In the railway industry, trust is built over time. It rests on a thorough understanding of operational constraints, consistent performance, and the ability of equipment to operate reliably over the long term despite mechanical, electrical and environmental stresses.
For more than 60 years, Crouzet has supported railway applications. This experience gives the company a deep understanding of the sector’s specific requirements: long life cycles, exacting reliability standards, controlled maintenance, traceability, continuity of supply, and adaptation to different system architectures. Every solution is therefore backed by practical knowledge of the conditions in which components will be integrated and used.
Expertise inherited from aerospace
Crouzet’s railway expertise also benefits from a technological heritage rooted in two other particularly demanding fields: aerospace and industries operating in harsh environments. In these sectors, components must retain their accuracy and reliability when exposed to repeated vibration, shock, temperature fluctuations or challenging operating conditions.
These capabilities are directly relevant to rail, where equipment is subjected to continuous stresses over long periods. Whether installed on board a train or integrated into infrastructure, components must perform consistently, even when their operating environment becomes especially demanding.
A culture shaped by critical environments
For manufacturers, integrators, equipment suppliers and operators, this culture of critical environments is a significant advantage. It enables railway projects to be approached with a detailed understanding of the required robustness, from the design phase through to operation in the field.
Crouzet therefore does more than supply technology. The company brings experience gained from applications in which availability, repeatability and endurance are essential. This expertise helps anticipate integration constraints, select the right technologies and contribute to the overall reliability of equipment.
At InnoTrans, Crouzet will highlight its ability to provide components designed to withstand shock, vibration and extreme conditions. The promise is simple but decisive: to give railway stakeholders solutions they can rely on, both today and over the long term.
A partner committed to the growth of rail
The railway industry is being driven by powerful long-term trends. Demand for sustainable mobility is growing, networks are being modernised, and both onboard systems and infrastructure are becoming smarter, more connected and more automated.
To support this evolution, suppliers must go beyond one-off responses. They need a long-term vision and must invest continuously in their technologies, expertise and manufacturing capabilities.
Supporting the long-term growth of rail
Crouzet brings a genuine growth mindset to the railway market. This begins with a lasting commitment to the sector. The goal is not only to meet today’s needs, but also to contribute to the next generations of railway systems by anticipating technical and industrial developments.
This commitment takes the form of continuous investment in technology and manufacturing resources. Developing new solutions, improving performance, adapting processes and strengthening industrialisation capabilities are all essential levers for keeping pace with market transformation.
In a sector where programmes can span many years, this continuity is a major source of confidence for customers. They must be able to rely on partners with a clear vision, enduring expertise and an organisation capable of supporting their projects throughout their entire life cycle.
This ambition is also underpinned by engineering expertise dedicated to future railway systems. Crouzet’s teams work closely with application requirements to understand integration constraints, performance targets and reliability challenges.
Addressing real-world needs
This proximity encourages a collaborative approach and helps identify the solution best suited to actual use. Technology is therefore considered as a response to a concrete need, rather than as an isolated element of the system into which it will be integrated.
In this context, innovation is not an end in itself. It must deliver tangible value: improving detection accuracy, securing a switching operation, simplifying control, optimising integration or increasing equipment durability.
By applying this approach to rail, Crouzet aims to support market players on their modernisation journeys without losing sight of the need for robustness and industrial control. The company therefore combines technological development with a clear understanding of the sector’s operational realities.
InnoTrans 2026 will provide an ideal setting in which to discuss upcoming projects, compare perspectives and identify new opportunities for collaboration. For Crouzet, taking part in the exhibition means looking beyond immediate needs and working with its partners to build the solutions that will equip the railway of tomorrow.
A resilient supply chain backed by global manufacturing capabilities
Recent years have highlighted just how strategic supply-chain resilience has become. In the railway industry, where programme continuity, parts availability and stable production are essential, a supplier’s industrial robustness is now a selection criterion in its own right.
A global manufacturing network
Crouzet operates a network of 15 production sites worldwide. This international footprint provides the capacity needed to serve customers across different markets, support a wide range of volumes and bring manufacturing expertise closer to regional requirements.
It also helps distribute capacity and reduce dependence on a single source. For international railway programmes, this coverage is a significant advantage, particularly when supporting several sites belonging to the same customer or deployments across different regions of the world.
At the heart of this organisation, Crouzet maintains a strong industrial footprint in France. This is complemented by carefully selected, cost-optimised production sites that combine competitiveness, quality and process control.
This structure makes it possible to adapt the manufacturing strategy to the nature of the products and customer expectations while maintaining consistent industrial governance. Depending on the need, projects can therefore benefit from specialist expertise, appropriate production capacity and an organisation designed to ensure continuity.
Resilience by design
Resilience, however, does not depend solely on the number of factories. It also relies on the quality of planning, secure flows, supplier management and the ability to respond to unforeseen events.
The challenge is to build a robust supply chain that can absorb disruption while maintaining the expected level of service. The ability to anticipate risks and adapt the industrial organisation is particularly important for programmes that require a high degree of consistency over time.
For railway stakeholders, the combination of a global presence, strong roots in France and rigorous selection of production locations provides a concrete advantage. It allows them to work with a partner capable of supporting their projects over the long term, meeting international requirements and deploying an industrial approach suited to both economic and quality expectations.
At InnoTrans, Crouzet will present this global capability not simply as a measure of scale, but as a means of delivering continuity, flexibility and confidence.
In a market where project performance also depends on the strength of the industrial ecosystem, a resilient supply chain has become essential. Crouzet’s international organisation addresses this challenge by combining global capabilities, customer proximity and industrial control.
Solutions for the entire railway ecosystem
Rail is a complex system in which rolling stock, infrastructure, human-machine interfaces, signalling systems, control devices and monitoring equipment all interact. Each function contributes to the network’s overall performance and must be integrated into a coherent whole.
Crouzet’s expertise spans applications both on board trains and within railway infrastructure. This breadth allows the company to operate at several levels of the ecosystem and meet the needs of many stakeholders: rolling-stock manufacturers, subsystem suppliers, integrators, signalling specialists and infrastructure equipment providers.
Supporting rolling stock—and beyond
In rolling stock, detection, switching and control technologies can support functions as varied as driver interfaces, control desks, access systems, auxiliary systems, and mechanisms requiring reliable information about a position or status.
In each case, the component must integrate precisely, provide a repeatable response and maintain its performance throughout its expected service life. Its role may be unobtrusive at train level, but it remains critical to the proper operation of the function it supports.
Interfaces used by drivers illustrate this challenge perfectly. They must enable precise, intuitive and reliable actions, repeated every day under varying operating conditions. The quality of control and switching devices directly contributes to the effectiveness of these interactions.
Components for railway infrastructure
On the infrastructure side, requirements include signalling and control systems in particular. These applications demand robust technologies capable of transmitting information or triggering an action reliably in environments subject to severe operational constraints.
Component performance therefore contributes directly to the availability and control of the overall system. Accurate detection, reliable switching or a correctly executed command can play an essential role in the day-to-day operation of an installation.
This presence across several application families also facilitates technical dialogue. Rather than considering each need in isolation, Crouzet can take into account the system architecture, interactions between functions and the customer’s overall objectives.
This broader perspective helps identify the most suitable technologies and optimise their integration. It also encourages the sharing of experience across different applications, environments and markets.
Through its participation in InnoTrans, Crouzet aims to demonstrate that its offering is not limited to a single application or one part of the train. From driver interfaces to signalling and control systems, the company supports the functions that transmit information, trigger actions and enable railway equipment to operate safely and reliably.
Performance tailored to critical functions
In many railway applications, incorrect information, imprecise switching or a failed command can have significant consequences for equipment availability, operation or safety.
The technologies integrated into these functions must therefore meet particularly demanding standards. They must be designed to operate reliably, repeatedly and durably despite the constraints to which they are exposed.
Solutions for critical applications
Crouzet develops detection, switching and control solutions for these demanding environments. Their role may appear basic, but it is often decisive: detecting a position, confirming a status, transmitting an instruction or activating a function at the right time.
In a complex system, the quality of these operations contributes directly to overall performance. Every interaction must be controlled, from the very first operating cycle through to the repeated operations performed throughout the equipment’s service life.
These technologies have proven themselves in critical railway functions. This experience makes it possible to build on feedback from use, better understand stress profiles and incorporate real-world constraints from the design stage onwards.
Reliability does not result from a single technical characteristic. It is built through the choice of architectures, mastery of materials, process precision, manufacturing repeatability and the suitability of the component for its environment.
Designed for demanding environments
Crouzet solutions are designed for demanding operating environments. They must continue to perform their function despite vibration, shock, temperature fluctuations, repeated cycles or long periods of operation.
This robustness is essential to reduce failures, support equipment availability and help keep maintenance operations under control. It also enables customers to integrate components with confidence into equipment whose performance must be maintained for many years.
In the railway industry, safety-related performance also depends on trust between partners. Customers must be able to rely on a supplier that understands the challenges of their applications and can translate those challenges into relevant technical and industrial choices.
Drawing on its experience in critical sectors, its commitment to rail and its mastery of detection, switching and control technologies, Crouzet is positioned as a partner capable of supporting the most demanding functions.
