Our approach

The project addressed the need to strengthen organisational knowledge and capability in relation to Technical Specifications for Interoperability (TSI) certification and the accreditation process for acting as a Notified Body (NoBo). The customer is involved in high-speed rail systems and required a structured understanding of authorisation processes applicable to rolling stock and infrastructure projects.

Increasing regulatory complexity and evolving European authorisation requirements made it necessary to build internal competence in certification workflows, roles, and responsibilities. The objective of the project was to establish a clear, practical and reliable framework for understanding, structuring, and managing TSI-related authorisation activities across different project types.

PROSE delivered interactive, on-site training workshops tailored to the customer’s specific role and regulatory context. Our approach combined structured theoretical input with practical examples drawn from real TSI certification and authorisation projects across the European railway sector.

Key elements of the TSI framework, the NNTRs, the CSM Regulation, the role of a Notified Body (NoBo), a Designated Body (DeBo), an Independent Assessment Body (AsBo), and typical certification and authorisation processes were explained step by step and discussed in detail with the participants. Throughout the workshops, PROSE addressed customer-specific questions and scenarios, ensuring direct applicability to ongoing and future activities.

Customer benefit

Through its collaboration with PROSE, the client gained a clear, structured and practical understanding of the certification and approval processes in accordance with the TSI, NNTR and other safety regulations. The training strengthened internal competence and confidence in dealing with regulatory requirements and interactions with external stakeholders.

PROSE’s independent position and broad industry experience ensured an objective and practice-oriented perspective, grounded in real-world railway projects. This enabled the customer to build sustainable internal know-how, reduce dependency on external clarification, and establish a solid foundation for future certification and accreditation activities.

Customer: HYPERLOOP Transportation Technologies Inc., USA

Project tasks

  • Review and assessment of existing conceptual bogie and chassis designs
  • Technical clarification with the customer and co-development partners
  • Development of a multibody simulation (MBS) model of the HyperTransfer vehicle
  • Representation of magnetic levitation forces using simplified spring models
  • Modelling all relevant kinematic degrees of freedom
  • Integration of mechanical backup suspension systems (wheels and/or skids) to analyse limit cases and residual clearances

Our approach

The project supported the early development and feasibility assessment of a magnetic levitation vehicle within the HyperTransfer concept developed by HYPERLOOP Transportation Technologies. The vehicle represents a new class of guided transport systems, combining railway vehicle engineering principles and magnetic levitation (maglev) technology.

In an initial step, the customer required an independent assessment of a conceptual bogie and chassis design to support ongoing feasibility studies and early design decisions. This required engineering expertise with proven experience in rolling stock design as well as magnetic levitation systems.

In subsequent development phases, the feasibility assessment of the HyperTransfer vehicle required a detailed multibody simulation (MBS) model. The model enabled dynamic simulations, derivation ofload assumptions, and kinematic analyses, providing a technical basis to support further design and validation activities.

PROSE applied a structured two-step engineering approach tailored to the early development phase of the HyperTransfer vehicle.

In the first step, we reviewed the existing design documentation, formulated targeted technical questions, and performed an independent assessment of the conceptual bogie and chassis design. This work was carried out in close collaboration with the HYPERLOOPTT design team and its co-development partners through technical meetings and focused design reviews.

In the second step, PROSE developed a multibody simulation (MBS) model representing the HyperTransfer vehicle. The model includes the capsule, the secondary suspension between capsule and chassis, and the load-carrying chassis components up to the primary suspension interface to the levitation magnets.

PROSE’s combination of railway vehicle engineering expertise and specific know-how in magnetic levitation systems differentiated our approach and ensured a technically robust and application-oriented solution.

Customer benefit

By working with PROSE, the customer received independent and experienced engineering support during a critical early development phase of the HyperTransfer concept. PROSE’s in-depth expertise in chassis and railway vehicle design, combined with practical experience in magnetic levitation systems provided valuable technical assurance.

The structured assessment and simulation-based approach enabled the customer to make informed design decisions identify technical constraints at an early stage, and reduce development risks.

PROSE’s ability to bridge conventional railway engineering and advanced maglev concepts enabled the customer in progressing efficiently from concept evaluation towards detailed development, with a clear and technically robust basis for further design activities.

AI-based tram rail lubrication system showing data acquisition from acoustics and GPS, fleet swarm intelligence, and predictive lubrication decisions.

Noise and wear reduction for trams with AI-based rail head lubrication

Customer: BERNMOBIL, Switzerland

Project tasks

  • Project management
  • Concept development
  • System integration
  • Data analysis

Our approach

The operation of a railway vehicle causes noise and wear on wheels and rails. These issues can be reduced by lubricating the wheel-rail contact point. However, excessive lubrication can pose a safety problem, as it reduces traction forces and increases braking distance, potentially causing ecological pollution.

Together with our partners, we have developed a system as part of a research project supported by the Federal Office of Transport (FOT) that makes it possible to condition the rail head as needed. Sensors installed on the vehicle measure status parameters and feed them to an AI installed on the vehicle. The machine learning model analyses the data, determines the need for conditioning and synchronises this with other vehicles operating on the rail network. Based on this information, each vehicle decides for itself at which point in the rail network conditioning must be initiated by the on-board lubrication system.

Customer benefit

In addition to fully automatic lubrication, the customer has access to comprehensive noise monitoring, which allows sources of noise to be localised at an early stage if they have not already been completely eliminated by the system. Since relevant influencing variables are known through the machine learning model, most noise sources can already be detected predictively and avoided altogether.

Communication between the vehicles creates a form of fleet-wide intelligence, enabling complete coverage of the fleet and the entire route network without having to equip each individual vehicle with expensive measurement technology. Thanks to the measuring system installed, other conditions can be monitored in addition to noise, such as ride comfort, wear between wheel and rail, and the infrastructure.

The customer benefits from our deep understanding of wheel–rail interaction and tram system behaviour, as well as our hands-on technical engagement throughout development.

  • Conceptdevelopment
  • Bogie andcarbody development
  • System integration

Our approach

Rhätische Bahn AG (RhB) plans to introduce a smart cruise control (SCC) function on its latest generation of multiple units as part of their automation strategy. The SCC function specifies an optimised speed and controls acceleration and braking between two station stops. In accordance with SN EN 62267, the SCC function is classified as Grade of Automation 1 (GoA1), as speed monitoring under the operating regulations (FDV) continues to be carried out by the locomotive crew.

A trackside platform (xx-TS) is planned for the SCC function. This trackside platform provides the necessary route and timetable data. It is based on existing specifications such as Automated Train Operation over European Train Control System (ATO over ETCS) in accordance with the Technical Specification for Interoperability relating to Control-Command and Signalling Subsystems (TSI CCS) and Connected Driver Advisory System (C-DAS). After registering with the train number, the train receives journey and segment profiles in accordance with SUBSET-126/SFERA. Transmission takes place via a mobile communications interface.

With the introduction of a Traffic Management System (TMS), a networked driver assistance system (C-DAS) will also be implemented, which displays energy-efficient and conflict-free driving recommendations based on optimised production specifications from the TMS.

PROSE was involved in the railway automation programme as co-project manager. We implemented a four-stage approach within the ATO-TS/C-DAS project:

  1. Existing requirements and specifications for the operational target vision were recorded and compared with the status quo of the ATO, TMS and C-DAS systems.
  2. Once the target vision and target architecture had been defined, a structured market evaluation was carried out and interviews were conducted with various system providers.
  3. Based on the market evaluation, a two-stage assessment of the solution options was carried out and proposals for the procurement strategy were developed.
  4. Further steps were implemented for the ATO-TS and C-DAS subsystems, including the execution of an RFI and in-depth analyses with selected providers.

Customer benefit

Thanks to our previous involvement in the railway automation programme and our combined operational and technical expertise, we were able to structure and advance the project with clear direction and efficiency.

Based on our market knowledge and cross-project experience, we were able to develop solution scenarios tailored to RhB’s operating environment. We moderated structured discussions with internal experts and programme participants, creating transparent decision-making and a solid foundation for the next implementation phase.

PROSE provided independent technical assessment, clear methodology and procurement support, laying the foundation for a clearly defined architecture and reduced implementation risk.

Conducting a feasibility study for fully automated shunting operations

Customer: tpf SA, Switzerland

Project tasks

  • Project management
  • Operational target
  • Technical feasibility assessment
  • Analysis of operational processes
  • Cost-benefit analysis

Our approach

The metre-gauge rolling stock used by the transport publics fribourgeois (tpf) operating on the Palézieux – Bulle – Montbovon line is maintained at the Planchy depot in the industrial zone of Bulle. The distance between Bulle station and the depot is around one kilometre. In current operations, staff must walk between the station and depot to perform shunting movements, which limits operational efficiency.

As part of recent service expansion , the infrastructure around Bulle has been modernised to current technical standards. In parallel with the planned modernisation of the Planchy maintenance facility, tpf investigated whether fully automated shunting operations using Automatic Train Operation Grade of Automation 4 (ATO GoA4) could be implemented with the existing vehicle fleet within the Planchy – Bulle area. The study assessed technical feasibility, operational implications, and the economic viability of introducing automated shunting.

PROSE supported tpf SA throughout the entire feasibility study in a structured, multi-stage process involving operational, technical, and management stakeholders. We first analysed the current operational processes, infrastructure, and regulatory conditions. Based on this, we jointly developed a target operating concept for automated shunting.

To evaluate possible implementation strategies, PROSE performed a risk analysis and developed several technically consistent solution variants using a morphological analysis method. These options were then compared through a transparent cost-benefit assessment, enabling a structured evaluation of technical feasibility and operational impact.

Customer benefit

tpf SA received a clear and independent decision basis for the further development of the Planchy maintenance site.

Thanks to the efficient approach, initial results were quickly developed in collaboration with tpf experts and presented to management. Technical feasibility, operational implications and economic effects were presented in a comprehensible and transparent manner.

With our expertise in railway operations and ATO realistic implementation scenarios were developed and efficiently aligned with internal stakeholders. PROSE also supported tpf in initial discussions with potential system suppliers, strengthening tpf’s technical and strategic position.
