Wear monitoring for meter gauge railway

Customer: Montreux-Oberland-Bahn (MOB), Switzerland

Project tasks

  • Project management
  • Concept development
  • System integration

Our approach

The Montreux Oberland Railway (MOB) was faced with a challenge when it was suddenly confronted with increased noise and heavy wear on the wheels and rails of a large number of vehicles in its fleet. Various vehicles showed unexpectedly high signs of wear.

PROSE carried out two days of acoustic measurements on a vehicle travelling on the MOB network. We used wireless microphones that were magnetically attached under the car body on each side of the train. The acoustic signals were sent wirelessly to a laptop inside the vehicle. With the help of special acoustic software, these acoustic signals were transferred from the time domain to the frequency domain in real time. Based on the amplitudes in certain frequencies, the problem of noise and wear in certain curves of the network could be localised. Additional measurements on the rails showed that the wheel flange lubrication on the rail was inadequate and was causing noise and wear. After manually lubricating around 10 curves on the 45 km network, the wear disappeared completely and the noise was reduced.

Customer benefit

The MOB had to reduce its services as the wear and noise pollution were no longer acceptable. After the problem was analysed and localised by PROSE-experts on the MOB network within a day of the measurement, noise and wear were reduced to a minimum and the MOB was able to resume regular operations.

 

  

Cybersecurity Awareness

Project tasks

  • PROSE presentation on the current state of the railway industry
  • PROSE presentation on the future development of the railway industry
  • In-depth discussion on TS 50701, security vs. safety and discussion on standards
  • Interactive brainstorming on the gap analysis
  • Consolidation of the results of the gap analysis and prioritisation
  • Analysis of the customer’s security documentation
  • Summary and definition of the next steps and goal

Our approach

The digital transformation of the rail industry is accelerating at an unprecedented pace. With increasing connectivity comes the urgent need to improve cybersecurity frameworks to ensure resilience against evolving threats. A recent industry workshop highlighted key findings on the current state of cybersecurity in railway systems and the expected regulatory changes that will shape the future.

Security in the railway sector has traditionally focused on protecting people and machines. However, cybersecurity has now become a critical factor in protecting IT systems, infrastructure and sensitive data. Despite their relevance, many existing railway standards provide only limited guidance on cybersecurity. Important standards such as EN 50126, EN 50716 and EN 50129 recognise security concerns but do not provide concrete measures. The IEC 62443 series, which emerged in the 2010s, has become a fundamental security framework, but its full integration into railway systems is still a work in progress.

A key challenge in cybersecurity is the human factor. Unclear role definitions in projects can lead to security risks – for example, through software updates that are implemented without sufficient validation and can compromise critical systems. Clear role definitions and structured safety processes are necessary to minimise such risks.

The future of railway safety will be shaped by new guidelines and harmonised standards designed to close existing safety gaps. Several regulatory developments will redefine safety requirements in the sector. The NIS 2 Directive obliges operators of critical infrastructure, including the railway industry, to take comprehensive cybersecurity measures. Companies in the supply chain will also have to prove their compliance in future.

The Cyber Resilience Act (CRA) places strict security requirements on manufacturers and suppliers of digital products, including railway technology. IEC 63452 is expected to become a global benchmark for cybersecurity in railway systems and combines elements from IEC 62443 and TS 50701 to create a standardised security framework. In addition, there is a trend towards common cybersecurity services – for example in the areas of authentication, logging and network security to ensure standardised protective measures for critical rail systems.

Customer benefit

Railway operators, manufacturers and suppliers must proactively adapt to these new regulations. Key recommendations include:

  • Identification and inventory of all assets (especially SW)
  • Conducting cybersecurity risk assessments to identify vulnerabilities
  • Establish clear security requirements for suppliers and ensure compliance throughout the value chain
  • Implementing security-by-design principles in the development of new products
  • Strengthen security incident response capabilities to effectively manage threats

By taking a proactive approach, the industry can ensure the safety, reliability and resilience of railway systems in an increasingly connected world.

Validation Maintenace activities- Mälartåg

Customer: AB Transitio, Sweden

Project tasks

  • Validation of the maintenance process

Our approach

Transitio, as the owner, and MTR, as the operator of the Mälartåg trains, are responsible for validating the maintenance processes. This validation serves to complete the maintenance instructions and identify efficiency improvements in the maintenance processes. The train manufacturer Stadler is obliged to fulfil the contractually agreed specifications to ensure that maintenance is carried out to the highest standards.

The validation of the maintenance process is divided into five main phases:

  • Requirements planning and definition: This is where requirements are determined and clearly defined.
  • Definition of specifications and configurations: In this phase, the exact specifications and configurations are determined.
  • Verification: This phase serves to carefully review the previously defined specifications and configurations.
  • Utilisation: After the definition of requirements, design and qualification, which includes testing and commissioning, the utilisation phase follows. During this phase, continuous checks are made to ensure that the validated status is maintained. This is usually the longest phase and aims to ensure that the defined standards are continuously met throughout the entire service life.
  • Decommissioning: The final phase involves the orderly decommissioning of the system while maintaining the documented standards until the end.

The aim of this structured procedure is to maximise efficiency and safety.

Customer benefit

Monitoring the initial qualification of devices and compliance with defined processes during the utilisation phase are essential. This enables effective process verification, which allows potential deviations to be recognised at an early stage. In this way, preventive measures can be taken before deviations occur.

Digitalisation of maintenance requirements

Customer: SBB Historic, Switzerland

Project tasks

  • Research: Review and analysis of the existing documentation (e.g., old regulations)
  • Expert Interviews: Enrichment of the database with know-how from specialists
  • Documentation: Creation of maintenance plans for the 14 rail vehicles and 3-4 wagon fleets
  • Approval: Incorporation of client feedback and final adjustments

Framework conditions:

  • Utilisation of old regulations as the basis
  • Supplementation through reverse engineering and other methods to address data gaps
  • Collaboration with the client, particularly in providing knowledge and feedback

Our approach

The project was initiated by SBB Historic to gradually align the existing maintenance organisation and fleet management with European standards. The core challenge lies in transforming a fragmented documentation base. Many of the historic vehicles have only partially available operational and maintenance manuals, as the original manufacturers either no longer exist or the documentation has been lost over time.

Additionally, the introduction of the ZEDAS maintenance software is intended to support and future-proof the maintenance processes. The project aims to create a consistent and standard-compliant maintenance plan landscape for the historic rail vehicles, enabling efficient, safe, and resource-conscious maintenance. At the same time, the transition will ensure compliance with European norms and facilitate maintenance activities carried out by in-house teams, associations, and third parties.

To achieve these objectives, PROSE adopts a structured approach comprising several interconnected work steps. The process begins with extensive research, focusing on reviewing and analysing old maintenance regulations to compile and prepare existing content. Subsequently, PROSE conducts expert interviews to incorporate historical knowledge from specialists, fill existing gaps, or update outdated guidelines. Based on this, maintenance plans are developed for the 14 rail vehicles and three to four wagon fleets. These plans are created iteratively, incorporating client feedback to ensure a tailored solution. Finally, the plans are integrated into the new maintenance concept and adapted to the requirements of the ZEDAS software.

The PROSE team, consisting of experienced experts, guarantees a professional and quality-orientated implementation. If necessary, the team is supported by other experts to ensure the quality and efficiency of the implementation.

Customer benefit

The project provides the client with numerous advantages that go beyond merely developing maintenance plans. By establishing a consistent, standards-compliant planning framework, the maintenance of historic vehicles can be carried out safely, efficiently, and cost-effectively. The integration of existing regulations and the supplementation of missing content through expert interviews not only reduces time and financial expenditure but also ensures that the plans are highly practical and relevant.

Another significant benefit lies in the introduction of the ZEDAS maintenance software, a key component for future digitalisation and optimisation of processes. The combination of technical and operational expertise provided by PROSE ensures that the plans are seamlessly integrated into the new software ecosystem, creating a high level of efficiency and transparency.

With transparent pricing and an agreed cost ceiling, the project remains financially predictable and manageable. At the same time, SBB Historic and the participating organisations benefit from PROSE’s extensive experience and proven competence. PROSE delivers tailored and sustainable solutions in the railway sector. The outcome is not only technically flawless but also an economically viable solution that guarantees the long-term safe operation of the historic fleet.

 

 

General Contract of Use for freight wagons (GCU) in Railway Undertakings (RU)

Customer: SBB Cargo, Switzerland

Project tasks

  • Analyse the current state, identify weaknesses and strengths, and document responsibilities and workflows
  • Develop a target model with clear responsibilities, efficient processes, and the use of new digital tools such as the GCU-Broker
  • Implement the new processes, including employee training and the establishment of overarching responsibility for GCU

Our Approach

The project to optimise the GCU (General Contract of Use for freight wagons) tasks within SBB Cargo’s RU (Railway Undertaking) role addressed the growing demands of European freight transport and the increasing expectations for legal and process compliance. The primary goal was to establish a clear and robust organisation of responsibilities within the RU role, meeting both the requirements of the GCU and relevant EU regulations. This realignment was achieved through a systematic review of existing processes and structures. Key challenges included the precise delineation of roles between the railway undertaking and the wagon keeper, as defined by the GCU provisions. In particular, the requirements arising from oversight by the Swiss Federal Office of Transport (FOT) necessitated reorganisation, as unclear responsibilities had previously hindered audit outcomes.

Additionally, action was required for key operational processes such as the re-commissioning of freight wagons after repairs, the verification of GCU-compliant wagons within train formations, and the retrieval of technical wagon data from third-party keepers. These areas are critical for ensuring safety and quality standards. At the same time, the entire scope of GCU tasks is subject to increasing regulation, which will be further intensified by the BAV (Federal Office of Transport in Switzerland) from 2026 onwards. To meet these demands, SBB Cargo’s internal processes must not only become more efficient but also legally sound.

The project was implemented in multiple phases. In the first phase, the current state of GCU tasks was documented, and key strengths and weaknesses were identified. This analysis was completed by May 2024. Building on this, by August 2024, a target process was developed that defines clear responsibilities, optimises existing workflows and incorporates digital solutions such as the GCU-Broker. This tool is intended to replace the manual processing of damage reports, thereby modernising data exchange. Starting in January 2025, the target process will be implemented, with a focus on appointing a central overall responsibility for GCU tasks, covering both strategic and operational duties. The project team included PROSE internal experts and external consultants from BAHNVERSTAND, who provided methodological support and strategic recommendations.

Customer benefit

​The implementation of the project delivers significant benefits for customers through more efficient and reliable handling of GCU tasks. Clear responsibilities and improved processes reduce delays and enhance legal certainty in operations. The integration of digital solutions, such as the GCU-Broker, lowers administrative costs and accelerates data exchange. Furthermore, compliance with new legal requirements, particularly EU and FOT regulations, ensures long-term legal security and minimises liability risks. Overall, the project strengthens SBB Cargo’s position in the European freight transport market and ensures sustainable future viability.
