Project management and remote monitoring for a Proof of Concept SS-149

Customer: SBB, Switzerland

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. The customer could rely on PROSE to manage the project without needing to build up internal resources. In addition our independent advisory role ensured a neutral perspective, while maintaining alignment between the various stakeholders involved in the project.

 

  

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.

Aerodynamics simulation (CFD)

Customer: Various customers

Project tasks

​During the development process or during modernisation, aerodynamic influences such as crosswind or vehicle air conditioning of a vehicle must be assessed. Often the final verification requires investigations in a wind tunnel or climatic wind tunnel. However, CFD (Computational fluid dynamics) simulations are ideal for an initial assessment and optimisation, as they generally provide reliable results at significantly lower cost.

Analyses:

  • Crosswind stability (aero-dynamic coefficients and wind characteristics curves) according to EN 14067-6
  • Climatic studies and thermal comfort

Our Approach

Crosswind assessment according to EN 14067-6

The EN 14067-6 provides for the evaluation of crosswind with aerodynamic coefficients, which can be obtained either by wind tunnel tests or by CFD simulations. PROSE can determine these coefficients by CFD simulations and derive characteristic wind curves. The influence of the vehicle design on the crosswind stability can be considered in the design phase. In the case of changes to the vehicle exterior shape during conversions, the influence can be assessed and in the case of minor changes, proof of crosswind stability can also be provided.

Investigation of vehicle air conditioning

CFD simulations allow first estimations for climatic-technical investigations according to European standards, which are based on tests in the climatic wind tunnel. An optimisation with CFD simulations within the scope of the design of the air conditioning system generates additional safety and can avoid costly adjustments and repetitions of measurements in the climatic wind tunnel.

Customer benefit

PROSE can support you during the development process or during a modernisation with CFD simulations to reduce costs and risks of wind tunnel and climatic wind tunnel tests.
