Modernisation – Our solutions

Fire protection monitoring technology IC 2000

Customer: SBB, Switzerland

Project tasks

  • Risk analysis for fire protection of the technical components
  • Conceptual design of fire protection monitoring
  • Integration concepts for the different vehicles
  • Electrical integration
  • Complete installation and maintenance documentation
  • Verification documents for approval

Our Approach

Beforehand, PROSE had already developed an initial concept for the cable routing and carried out a risk analysis of the affected components. Together with the component supplier, PROSE then developed a detailed concept for the mechanical integration of the LHD cable and the other components required for monitoring in the vehicles. After the conversion of the first prototypes, the complete documentation as well as the proofs for the approval were prepared by PROSE.

Customer benefit

In particular, the customer was able to benefit from the comprehensive know-how of PROSE’s experts, who were able to comprehensively narrow down the complex topic of fire protection monitoring and its integration based on their knowledge of the vehicles. Due to the intensive support of the workshop, questions could be clarified immediately and thus the target dates could be optimally met.

Finite element analysis and strength verification for folding seats in the AS coach

Customer: FAINSA, Spain

Project tasks

  • Strength calculation of the folding seats
  • Proposals for optimisation and recalculation of the design
  • Final verification calculation with final report

Our Approach

In order to be able to implement the project, CAD 3D models of three seat types were provided by the customer. The models were read into the FEA software by PROSE and analysed. Based on the results and in close cooperation with the customer, various optimisations of the designs were made. These optimisations were recalculated and, if necessary, further improved in the construction. After the optimised designs met the requirements of UIC566, a final report could be prepared with the proof of strength requested by SBB. This report was required as an initial type test document and also served the end customer as a verification document for the seats in order to obtain approval for the passenger coaches.

Customer benefit

Our engineering services provide the customer with optimised seat designs whose strength can be verified. The knowledge of the approval processes and the end customer-specific requirements enable PROSE to create “approval-proof” documents that can be accepted by the end customer. Our knowledge of local conditions and experience as an internationally active company enables us to build a technical and formal bridge between the seat supplier and the end customer.

Brake and thermal calculation locomotive Aaem841

Customer: Müller Technologie AG, Switzerland

Project tasks

  • Define and obtain input data
  • Brake calculation in TrainBrac
  • Thermal calculation in ANSYS
  • Specification and selection matrix for brake blocks

Our Approach

PROSE defines and procures the input data based on the relevant standards, which are required for the approval of the vehicle. Subsequently, the calculations were carried out and optimized so that the defined requirements were met. For this purpose, a brake calculation in TrainBrac was created in close coordination with the customer, as well as a thermal brake calculation in ANSYS, in order to prove the performance of the brake.  PROSE also contacted various brake block suppliers for possible linings on the basis of the specifications and calculation results and prepared a selection and decision matrix for Müller Technologie AG, including recommendations for the selection of a suitable lining.

Customer benefit

Thanks to PROSE’s expertise in this field, the customer receives documents to prove the performance of the modernised brake, which comply with the relevant standards and can thus be submitted 1:1 to the assessor/expert to achieve approval. Furthermore, the specification and pre-evaluation of the brake blocks material with decision support enables an efficient enquiry of possible suppliers.

Computational evidence of derailment safety for rack railway wagons

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 rack railway container wagon to be investigated, as well as of the coupled train configuration
  • Execution and evaluation of the simulation
  • Documentation in an evidence report

Our Approach

At first, PROSE compiled all parameters required for modelling and simulation based on the customer’s data. Subsequently, the braking scenario relevant to the approval was determined and agreed upon with the customer. PROSE created the rack railway container wagon’s multi-body simulation model (MBS model) in the required modelling depth. The overall model of the train included a simplified MBS model of a flat wagon and the already at PROSE existing model of an HGe 4/4 II locomotive. PROSE simulated the most critical operational cases and documented the results and assessment of the simulations in an evidence report for the approval authority.

Customer benefit

The customer received an evidence report for the approval documentation, which clearly and comprehensibly documents the computational proof of the safety against the derailment of the rack railway container wagon. Based on the evidence, the customer received the approval for the wagon.

Engineering project IC2020-fleet

Customer: SBB, Switzerland

Project tasks

Our Approach

In a first step PROSE investigated the measures identified by SBB in the study phase and worked out the concept. PROSE prepared the technical procurement documents, such as specifications, technical requirement catalogues and interface drawings. The offers submitted by the potential suppliers were technically evaluated by PROSE and adjusted in the course of the technical negotiations. In the detailing phase, the system to be delivered was integrated into the vehicle documentation in cooperation with the suppliers who were awarded the contract by SBB.

Customer benefit

An international team of specialists from 4 countries is involved in the project at PROSE. Due to the project organisation PROSE is close to the customer SBB and therefore part of the overall project team. The creation of the production documents was done directly in the IT environment of SBB.
