Development of rail operation and technology strategy 2050

Customer: Rhätische Bahn AG, Switzerland

Project tasks

  • Strategy development
  • Analysis and conception
  • Stakeholder management & methodology
  • Project management, incl. Stakeholders, Communication and Change-Management

Our Approach

Due to the technology’s long life cycle and high investment volume, investments in railway technology require a comprehensible focus and demonstrable benefits. In collaboration with the RhB specialists, PROSE developed an operational target picture and operational use cases for the year 2050 based on the identified challenges of daily operations. Based on this target picture, the benefits created by technology and target systems are clearly identified, and the technology strategy can be aligned with the fulfilment of the target picture.

Based on the operational target picture, the ACTUAL system architecture and the known life cycles were recorded with the RhB experts. Based on the information on the current situation, PROSE was able to develop a proposal for the TARGET system architecture, including migration planning and implementation concepts.

With the help of modern methods and targeted workshops, PROSE and RhB achieved the project goal in a very short time and presented the first results to the strategic steering committee.

Customer benefit

RhB benefited from the PROSE experts’ overall system knowledge and technical expertise in railway operations & automation. In combination with the methodical and analytical approach of the PROSE project team, RhB was able to develop and discuss initial approaches for the implementation of the strategy across all areas. This includes, for example, a migration map with the life cycle of systems and vehicles to identify possible migration windows for the systems, the visualisation of the operational target processes with the target degree of automation and possible implementation variants on the RhB route network.

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 optimization, 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 optimization 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 modernization with CFD simulations to reduce costs and risks of wind tunnel and climatic wind tunnel tests.

 

 

Optimisation of the heavy overhaul program for the Tram “Cobra”

Customer: Verkehrsbetriebe Zürich, Switzerland

Project tasks

  • Development of an evaluation matrix based on the VBZ vehicle structure
  • Determining which measures are to be implemented within the framework of R3
  • Development of a project manual applicable to the project

Our Approach

PROSE develops an evaluation matrix based on the VBZ vehicle structure so that it can be determined which measures should be implemented within the framework of R3. The evaluation matrix contains criteria according to which the measures can be evaluated, including an evaluation. PROSE is developing a project manual applicable to the CR3 project. The focus is on the definition of the different phases including their objectives, duration and contents. It also explains which project participants and stakeholders should be involved, when and how, and how responsibilities should be defined.

Customer benefit

The methodology and tooling provided by PROSE in the first phase enables VBZ to efficiently plan and implement Revision 3 and the life extension measures. The evaluation matrix enables VBZ to make informed decisions about which measures should be implemented as part of R3. This helps to use resources effectively and to keep the trams in the best possible condition. The project manual is the basis for VBZ to implement the Cobra tram overhaul and service life extension project in a structured and effective way, resulting in cost savings and efficiency gains.

     

MBS simulation – trailer load with container car

Customer: Matterhorn Gotthard Bahn AG, Switzerland

Project tasks

  • Compilation and preparation of parameters for modelling and simulation
  • Determination of the braking scenario to be considered
  • Creation of a multi-body simulation model (MBS model) of the cogwheel supporting wagon to be investigated as well as of the coupled train configuration
  • Execution and evaluation of the simulation
  • Documentation in a verification report

Our Approach

PROSE is to prove by simulation that derailment safety is given with the new requirements and to develop a set of arguments that can be submitted to the BAV to adapt the driving service regulation.

In a first step, PROSE compiled all the parameters required for modelling and simulation on the basis of customer data. Subsequently, the braking scenario was determined and agreed with the customer. PROSE created the multi-body simulation model (MBS model) of the container car in the required modelling depth. The overall model of the train set included a simplified MBS model of the necessary vehicles for the combinations to be verified in addition to the carrying car to be investigated. PROSE simulated the operationally most critical cases and recorded the results and evaluation of the simulations in a verification report for the attention of the approval authority.

Customer benefit

The customer received a verification report for the approval documentation, which clearly and comprehensibly documents the mathematical proof of safety against derailment of the cogwheel carrier car. On the basis of the proof, the customer was able to obtain the adjustment of the driving service regulation from the BAV.

Leadership Coaching and Strategy Consulting Digital Interlocking

Customer: SBB Infrastructure, Switzerland

Project tasks

  • Leadership Coaching
  • Strategy Consulting
  • Stakeholder Management

Our Approach

PROSE is carrying out the leadership coaching and strategy consulting for the SBB project manager “EESA 3.1 – Industrialised Rollout”. The leadership coaching was conducted between the poles of the rollout implementation, defined in the directional decision, and the call for tenders, which had to be prepared concurrently. On the one hand, the time constraints associated with the implementation were addressed, which led to good progress in the conceptual and content-related work. On the other hand, the strategy consultation dealt with prioritising the tender contents, whereby the implementation of innovations and the inclusion of essential rollout requirements were subordinated to securing the contract.

Customer benefit

In addition to more minor and continuous further developments of concepts, significant successes were also achieved in some areas. From a project management perspective, the following topics deserve special attention:

  • Publication of EULYNX Baseline 4.1 with the necessary adaptations for Switzerland.
  • Concluded procurement of a proof-of-concept platform for the Object Controller to demonstrate software separation, security features and a reference implementation of the Rail Safe Transport Application (RaST).
  • Results of the first iteration in the study, “Expandability using the example of the Dagmersellen – Emmenbrücke line”, showing a cost-saving potential between 50% and 75%.
  • Make-or-buy workshop with infrastructure management
