Design and authorisation strategy for a rail-bound maintenance machine

Customer: SCHÖMA, Germany

Project tasks

  • Vehicle authorisation strategy
  • Design assurance (Systems Engineering)
  • Concept development
  • Technical evaluation of offers and technical coordination with suppliers
  • Project management

Our approach

SCHÖMA plans to develop a proven, powered, three-part rail-bound maintenance machine with cab, loading platform and crane called HERO. SCHÖMA needs support in developing the authorisation strategy to fulfil the EN 14033 standards and in defining the design process including verification and validation.

PROSE developed the decision-making basis for the authorisation process enabling a defined combination of the three vehicles of the working machine to be approved and the verifications and evidence according to EN 14033 to be provided. PROSE also supported SCHÖMA in the budget planning phase of the development of the HERO work machine in the evaluation of supplier offers for systems and components such as the power train, braking system, power generation, train protection (ETCS) and heating, ventilation and air conditioning (HVAC). In addition, PROSE defined the design phases and the design assurance process according to the systems engineering methodology to ensure a defined and structured design process.

Customer benefit

PROSE has structured and optimised SCHÖMA’s development process by systematically applying the system engineering methodology. This approach has not only minimised development risks associated with costs and timelines but has crucially enhanced the predictability and likelihood of obtaining the necessary authorisation.

 

          

Vehicle Authorisation

Customer: various customers

Project tasks

  • Carrying out requirements capture and preparing the safety evaluation, including risk analysis
  • Preparation and management of evidence documents
  • Cooperation and coordination of NoBo, DeBo and AsBo
  • Support in preparing several declarations and dealing with online registers like ERATV or ERADIS
  • Management of the change notification to the ERA or national safety authorities like EBA for changes not requiring an authorisation
  • Management of authorisation applications via One Stop Shop to the ERA for changes requiring authorisation
  • Coordination with the ERA and national safety authority

Our Approach

Vehicle operators or leasing companies make changes to their vehicles for very different reasons, e.g. for obsolescence reasons or to offer passengers a better service by customising the interior and adding features such as sockets or WLAN. In addition to providing engineering services, PROSE supports such projects by taking over the entire approval management process, including communication with all the bodies and authorities involved.

The authorisation process ensures safe rail transport and the best possible interoperability throughout the EU. However, implementing changes to rolling stock presents a significant challenge to operators, keepers, and owners.

At PROSE, we recognise that each railway vehicle is unique. Our team of experts develops vehicle authorisation strategies that address the specific challenges of our customer’s products and needs. From Requirements Capture to One Stop Shop, our experts have the knowledge to guide you through the process. Whether you only need assistance with a single task or are looking for a complete solution, we can provide solutions to meet your particular requirements.

Customer benefit

Modernisations and retrofits guarantee enhanced reliability and superior passenger comfort and open up new applications by integrating new systems. Whilst operators and workshops can focus on their primary tasks, PROSE can handle all the “paperwork” from the engineering and the preparation of evidence documents to the assessment and authorisation phases with bodies and authorities involved. Due to our comprehensive service portfolio, we help reduce interfaces and effort because all services are coordinated and come from a single source.

PROSE ensures that our customers’ railway vehicles comply with the latest standards and regulations. From document preparation to submission, we make sure that vehicle approval hurdles don’t derail your success.

 

      

Vehicle procurement – Manufacturing Supervision, Quality Control and Factory Tests

Customer: various customer

Project tasks

  • Acceptance of the welded car bodies / bogie frames
  • Paint inspection and acceptance
  • Intermediate acceptance of main electrical components
  • Intermediate acceptance of interior fittings
  • Factory acceptance/customer acceptance

Our Approach

By regular participation in the vehicle acceptance tests and constant coordination with the team of the vehicle manufacturer, PROSE checks the quality of the production. The customer is permanently kept up to date by the acceptance team regarding the progress of the production as well as possible complications or deadline postponements. He immediately receives the results of the production controls and acceptances and can follow up changes, modifications etc.

The dates for the acceptance of components, intermediate assembly stands and vehicles ready for delivery follow the production plan but are also handled operationally and flexibly in order to be able to react to specific occasions. In this way, control of the construction process is always ensured and there is the possibility of intervention in the event of difficulties such as quality slumps, scheduling, supply, or capacity problems.

Customer benefit

With manufacturing supervision, the manufacturer’s quality assurance process is checked and monitored in addition to the product quality, because every vehicle has gone through this process before it is presented for factory acceptance. Continuous construction supervision ensures consistent quality at a high level.

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.
