The result is a future-ready solution that supports safe, efficient, and well-documented winter operations.

Integration and Authorisation Management: Polish Train Radio, Radio Stop Module, Interior and Exterior Foliation

2025-08-21

Customer: ODIG – Ostdeutsche Instandhaltungsgesellschaft mbH, Germany

Project tasks

Integration engineering of the Polish train radio
Integration engineering of the radio stop module
Adaptation of the MESA23 system
Consideration of the interior and exterior foliation as well as the modification of the train radio system within the verification process
Homologation management
Authority communication

Our approach

ODEG – Ostdeutsche Eisenbahn GmbH operates passenger transport services in northern and eastern Germany. The fleet consists of Desiro Classic (BR 642) multiple units, among others, manufactured by Siemens Mobility (SMO). The maintenance and repair of the vehicles is carried out by ODIG – Ostdeutsche Instandhaltungsgesellschaft mbH. This is a 100% subsidiary of ODEG. The vehicles currently operate with the existing German authorisation and a German train radio system on a section of line that runs over Polish territory. In future, the vehicles will have to be equipped with Polish train radio system and a radio stop module (RSM). The RSM is a device that is connected to the existing train radio system and integrated into the vehicle’s safety loop via an electromagnetic valve. In this way, the responsible dispatcher can give the “radio stop” command, which opens the vehicle’s safety loop and brings the vehicle to a standstill. In addition, interior foliation in the WC and full-surface exterior foliation had to be installed.

The functionality of the existing MESA23 system will be expanded to include operation with Polish train radio and the radio stop module (RSM). The foliations are handled with regard to all requirements.

Customer benefit

Thanks to the cooperation with PROSE, the customer was able to successfully convert the Desiro Classic railcars (BR 642) to use Polish train radio and the radio stop module (FSM). This not only offers ODEG passengers increased safety during the journey, but also enables smooth operation on the section of line through Polish territory. The application of the interior and exterior foils also contributes to the attractive appearance of the vehicles.

PROSE managed the project from the initial idea to the authorization strategy, preparation of evidence documents and coordination with NoBo/DeBo/AsBo through to communication with the authorities, so that ODIG was able to obtain a significant part of the project scope from a single source.

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

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.
