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.

Co-leading the Driver Advisory System and trackside platform for Automated Train Operation

Customer: Rhätische Bahn AG, Switzerland

Project tasks

  • Project management
  • Requirements capture
  • 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.

Our approach

As part of the ERTMS strategy of the Federal Office of Transport (FOT), Swiss infrastructure operators developed a long-term implementation concept for the network-wide introduction of cab signalling based on the European Train Control System (ETCS) Level 2.

PROSE supported BLS Netz AG in finalising the integrated rollout plan. We reconciled the different requirements of long-distance, regional and freight transport companies regarding rolling stock with the operational needs of the infrastructure. In parallel, we took the life cycles of existing systems and their depreciation effects into account.

On this basis, we developed a consolidated best-case scenario that defines the section-by-section implementation and commissioning, while transparently outlining the resulting investment and depreciation effects.

PROSE supported BLS in project management during the final phase of the implementation concept. Based on the selected best option:

  • We refined the planning with the involvement of all stakeholders
  • Quantified the resulting costs and depreciation
  • Coordinated the final draft resolution internally and externally with the other infrastructure operators.

The implementation concept is based on an integrated consideration of the life cycles of rolling stock and infrastructure. At the same time, the various potential benefits of ERTMS were systematically taken into account. A key element was to ensure operationally manageable migration through coordinated, coherent implementation, with the clear aim of avoiding fragmented ETCS island solutions.

Customer benefit

BLS Netz AG benefited from our comprehensive understanding of the planning triangle of operations, infrastructure and rolling stock, as well as our in-depth expertise in the field of ERTMS. Our structured methodology and independent consulting services provided a robust, coordinated basis for decision-making. The implementation concept was completed on schedule and in close cooperation with the specialists and programme management. PROSE embodied technical clarity and independent expertise.

  • Maximum vehicle mass: 61 t
  • Minimum vehicle mass: 58 t
  • Maximum wheelset load: 15.25 t

Our approach

The project is part of a shunting locomotive platform programme in which SCHÖMA supplied a shunting locomotive to Alstom for a transport authority in Manila, Philippines. The vehicle is a four-axle, diesel-hydraulically driven shunting locomotive for standard gauge with a total vehicle mass of 60 tonnes. PROSE was commissioned to carry out the complete mechanical development of the bogie.

The scope included the design and engineering of the bogie frame, wheelsets, axle boxes, and the integration of all relevant systems and components. A key technical focus was the limited available installation space and, the safe transmission of longitudinal traction and braking forces from the bogie to the carbody, without significantly altering wheelset loads. The project therefore required a robust, space-efficient, and safety-compliant bogie design suitable for effective production and reliable operation.

At PROSE, rail vehicle development follows the V-model in accordance with EN 50126. For this project, the bogie development was focused on the concept design and final design phases, ensuring an efficient and targeted engineering process. Throughout the development, PROSE placed particular emphasis on a production-oriented design approach, using cost-effective and manufacturing-friendly welded structures wherever possible.

In parallel, the design was optimised regarding both production and life-cycle costs, while consistently meeting safety and performance requirements. Compliance with all relevant safety-related EN standards was embedded in the design process. PROSE’s extensive experience in bogie engineering and our deep understanding of standards and manufacturing constraints enabled a balanced and efficient development approach tailored to the customer’s needs.

Customer benefit

Thanks to the timely and successful completion of the project, the customer received rapid and reliable engineering support within a short timeframe. By selecting PROSE, the customer benefited from in-depth expertise in bogie development, significantly reducing internal effort and development time. PROSE delivered a complete, production-ready bogie design, including a full 3D model, proof of strength, track guidance analysis, and detailed component specifications to support procurement.

All relevant systems, including primary and secondary suspension dampers, gearbox, brake system, and longitudinal and transverse stops, were successfully integrated. The critical challenge of transmitting longitudinal forces without increasing wheelset loads was solved through a cranked pull/push rod with a deep linkage connected to a balancer, resulting in low pitching moments and stable wheelset behaviour. Although no specific standards were required by the end customer, PROSE provided comprehensive and standard-compliant proofs of strength and derailment safety, demonstrating conformity with relevant standards such as EN 13749:2024, EN 13979, DVS 1612 and EN 14363:2016.

Project tasks

  • Project Management
  • Project Planning
  • Solution Architecture
  • Requirements Engineering
  • Sourcing
  • Supervision of the supplier’s Installation, Integration, and Commissioning
  • Data analysis and Reporting

Our approach

​Switzerland, as one of the first ETCS-only countries, required all active fleets to monitor malfunctioning Eurobalises, as per a national requirement (NNTR). With the TSI-2023 release, this NNTR had to be transferred and further developed into Subset–149, Online Monitoring System.

In December 2022, when the draft specification of the Subset–149, Online Monitoring System became available, PROSE was appointed by the rail infrastructure manager of Swiss Federal Railway to develop and conduct a Proof of Concept. The goal was to evaluate the suitability and completeness of the proposed protocol.

PROSE developed the system architecture and related requirements for an online monitoring of the MVB bus in the ETCS Onboard Unit (OBU) manufactured by Siemens and installed in a new Stadler FLIRT EMU owned and operated by Schweizerische Südostbahn. Railnova was identified as a suitable supplier and provided the related solution, both onboard (sniffer and gateway), and wayside. PROSE performed integration engineering as well as authorisation support.

Once the solution was in operation, PROSE closely monitored the wayside infrastructure and analysed the data and feedback to correct and improve the DRAFT Subset-149, contributing directly to its current maturity and reliability.

Customer benefit

With the assignment of PROSE, the customer benefits from the extensive experience of PROSE in the field of on-board signalling, ETCS and online monitoring, both wayside and onboard. PROSE’s combination of technical insight, hands-on experience, and understanding of the market landscape contributed to a solution that was both robust and fit-for-purpose.

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.

Independent technical and operational assessment of ATO GoA2 implementation variants

Customer: Rhaetian Railway, Switzerland

Project tasks

  • Expert interviews
  • Technical and operational assessment
  • Independent evaluation of implementation variants

Our Approach

As part of the development of a technical specification for equipping an existing vehicle fleet with a driver assistance system (DAS) / ATO GoA2 (Automatic Train Operation, semi-automatic operation) , PROSE supported Rhaethian Bahn AG (RhB) with neutral expertise on technical implementation variants.

Specifically, the focus was on the interface and functionality to be implemented for the interface between the DAS and the vehicle control system, as well as the interaction of the locomotive crew with the DAS. In particular, the different implementation variants focused on the DAS activation and implementing the traction/braking force target values on the vehicle.

Based on the European specification analogue to SUBSET-125 and SUBSET-139, the adapted draft specifications, and internal implementation proposals, PROSE carried out a neutral evaluation of the variants using a two-stage methodology.

In the first step, selected RhB representatives from the areas of vehicle technology and locomotive personnel were interviewed. The purpose of the interview was to determine the significance of the individual evaluation criteria.

In the second step, the PROSE experts verified the fulfilment of the criteria for both variants based on the technical specifications and the expert interviews. In particular, the opportunities, risks, suitability for vehicle acceptance, migration capability, acceptance of the systems by the locomotive personnel, and an initial qualitative assessment from the HOF (Human-Organisational-Factors) perspective of the variants were compared and evaluated.

Customer benefit

RhB benefited from the neutral and independent assessment of the PROSE experts and the methodical approach involving the relevant internal representatives. PROSE’s expertise ensured fast and efficient processing and the necessary depth of detail.
