Design of a 100% low-floor tram

Customer: CRRC Sifang Co Ltd, China

Project tasks

  • Tram concept
  • Design and development of bogie and carbody conceptual design and development
  • Electrical concept
  • Mechanical system integration

Our Approach

In cooperation with the client, PROSE developed the system specification for the whole tram and several of its components. One of the most challenging tasks in 100% low floor-trams is the design of the bogie, which had to be both compact and offer a quality ride. Single wheels were the solution.

Customer benefit

The newly designed 100% low-floor tram is a major upgrade of CRRC Sifang’s tram portfolio. The integration of CRRC Sifang’s production know-how and related processes into PROSE’s design work means lower production costs for CRRC Sifang.

 

Development of a gauge-changing facility for operator MOB

Customer: Chemin de fer Montreux Oberland bernois MOB, Switzerland

Project tasks

  • Feasibility analysis
  • Mechanical and control engineering development

Project tasks

  • Definition of requirements management
  • Creation of a standardisation framework
  • Delimitation of life cycle phase
  • Obsolescence management
  • RAMS & LCC Management

Our Approach

PROSE supports Knorr-Bremse and Rail Vision within their endeavor and defines the normative maintenance framework that builds the basis for a life cycle service contract upon installation of the electro-optic sensor systems.

Customer benefit

After prototype testing is successfully completed at the end of the first quarter of 2021, the partners will examine further business opportunities for integrating these systems into rail freight vehicles.

Car body (bodyshell) development

Customer: Vossloh Kiepe GmbH, Düsseldorf, Germany

End customer: Public transport company of Wuppertal, Germany

Project tasks

  • Development of the mechanical vehicle modules, i.e. car body and bogie
  • Project management
  • Definition and supervision of component tests
  • Homologation support

Our Approach

PROSE was responsible for the complete engineering of the main mechanical modules of the vehicle, which were the car body and the bogie.

Customer benefit

Given that PROSE was in charge of the vehicle development, customer VKD, who previously had been a component supplier, was able to expand its portfolio to the delivery of complete vehicles to the end customer. The know how of PROSE’s engineers in the field of turnkey engineering of complete vehicles, which is based on many years of experience with light-weight construction, was a basic condition for the successful results.

Development and delivery of module test stands for railroad construction machines

Customer: Plasser & Theurer, Export von Bahnbaumaschinen, Gesellschaft m.b.H., Austria

Project tasks

  • Development, delivery and commissioning of test benches for vehicle modules for construction machinery (e.g. power pack, cabin)

Our Approach

For the specific implementation of the tests, PROSE developed suitable algorithms for an optimal test process. PROSE was responsible for the complete delivery of the test stand in the project, from the conception and construction to the delivery of the fully assembled test benches.

Customer benefit

Plasser&Theurer benefited from PROSE’s engineering experience during the project. By outsourcing the entire development and engineering project, the customer had the advantage of having fully designed and assembled test benches available by the time the first vehicle modules were completed. The commissioning of the test benches by PROSE ensured that the components to be pre-tested only had to be mounted and connected to the test frame, which significantly reduced the overall production and commissioning time.

 

Cost Estimation for Object Controlling Software Development

Customer: SBB, Switzerland

Project tasks

  • Analysis of the modular concept
  • Verification of the basis technology
  • Estimation of the development time
  • Estimation of the development efforts
  • Evaluation of risks

Our Approach

As part of the industry program SmartRail 4.0, SBB are developing a concept for a geometric ETCS interlocking system. The Object Controller is the connecting element between the existing interlocking system, the new generation of interlocking systems and the existing trackside assets. To be able to estimate the basis technology and the development time as well as the development effort, PROSE was commissioned to evaluate the existing concept documents and to create the evaluation documents.

PROSE put together a team of experienced vehicle maintenance experts. The work contents and processes were systematically analysed and proposals for adjustments and possible improvements were formulated. In a second phase, the identified areas were discussed in workshops with specialists from RAlpin and the maintenance service provider and the final formulation of the work contents and processes for the regulations were determined. The documents were revised by PROSE and a new revision was prepared for release.

Customer benefit

SBB already has experienced employees in the field of safety-related systems. But since the Object Controller was very important for the migration, and to assure a higher precision in the estimation of development effort and time, as well as to identify further possible risks, PROSE was contacted for a second opinion. PROSE has employees experienced in signalling and software development as well as safety-related issues. These experiences are combined in a wellversed team to the benefit of the customer.

Leadership Coaching ECM2 Manager for life cycle extension locomotive Re620

Customer: SBB Cargo, Switzerland

Project tasks

  • Review of contents Re620
  • Technical Mentoring old Locomotives Fleet Manager
  • Leadership Coaching ECM2-Manager in Conceptualisation

Our approach

PROSE developed a three-stage concept as part of a professional coaching phase for the current ECM2 manager of SBB Cargo; taking into account the stabilisation of reliability and availability up to 2035 at the level of 2020 and the completion of revision R2 with a defined content, a planned annual mileage up to End of Life (EoL) of 120 thousand kilometres p.a. or 1.8 million km and a removal of the separation between light (SBB Cargo) and heavy maintenance (SBB-P, Bellinzona industrial plant), which had arisen as a result of the organisational split-up within the SBB Group.

Customer benefit

This concept gave SBB Cargo a sustainable opportunity to operate the strategically important Re6/6 fleet for a further fifteen years. The current ECM2 manager received management coaching at the appropriate level for the conception of a fifteen-year life extension for the Re620 (SLM) old locomotive from the 1970s.
