Customer: Rhätische Bahn AG, Switzerland

Project tasks

  • Project management
  • Requirements capture
  • Conceptdevelopment
  • Bogie andcarbody development
  • System integration

Our approach

Rhätische Bahn AG (RhB) plans to introduce a smart cruise control (SCC) function on its latest generation of multiple units as part of their automation strategy. The SCC function specifies an optimised speed and controls acceleration and braking between two station stops. In accordance with SN EN 62267, the SCC function is classified as Grade of Automation 1 (GoA1), as speed monitoring under the operating regulations (FDV) continues to be carried out by the locomotive crew.

A trackside platform (xx-TS) is planned for the SCC function. This trackside platform provides the necessary route and timetable data. It is based on existing specifications such as Automated Train Operation over European Train Control System (ATO over ETCS) in accordance with the Technical Specification for Interoperability relating to Control-Command and Signalling Subsystems (TSI CCS) and Connected Driver Advisory System (C-DAS). After registering with the train number, the train receives journey and segment profiles in accordance with SUBSET-126/SFERA. Transmission takes place via a mobile communications interface.

With the introduction of a Traffic Management System (TMS), a networked driver assistance system (C-DAS) will also be implemented, which displays energy-efficient and conflict-free driving recommendations based on optimised production specifications from the TMS.

PROSE was involved in the railway automation programme as co-project manager. We implemented a four-stage approach within the ATO-TS/C-DAS project:

  1. Existing requirements and specifications for the operational target vision were recorded and compared with the status quo of the ATO, TMS and C-DAS systems.
  2. Once the target vision and target architecture had been defined, a structured market evaluation was carried out and interviews were conducted with various system providers.
  3. Based on the market evaluation, a two-stage assessment of the solution options was carried out and proposals for the procurement strategy were developed.
  4. Further steps were implemented for the ATO-TS and C-DAS subsystems, including the execution of an RFI and in-depth analyses with selected providers.

Customer benefit

Thanks to our previous involvement in the railway automation programme and our combined operational and technical expertise, we were able to structure and advance the project with clear direction and efficiency.

Based on our market knowledge and cross-project experience, we were able to develop solution scenarios tailored to RhB’s operating environment. We moderated structured discussions with internal experts and programme participants, creating transparent decision-making and a solid foundation for the next implementation phase.

PROSE provided independent technical assessment, clear methodology and procurement support, laying the foundation for a clearly defined architecture and reduced implementation risk.

Conducting a feasibility study for fully automated shunting operations

Customer: tpf SA, Switzerland

Project tasks

  • Project management
  • Operational target
  • Technical feasibility assessment
  • Analysis of operational processes
  • Cost-benefit analysis

Our approach

The metre-gauge rolling stock used by the transport publics fribourgeois (tpf) operating on the Palézieux – Bulle – Montbovon line is maintained at the Planchy depot in the industrial zone of Bulle. The distance between Bulle station and the depot is around one kilometre. In current operations, staff must walk between the station and depot to perform shunting movements, which limits operational efficiency.

As part of recent service expansion , the infrastructure around Bulle has been modernised to current technical standards. In parallel with the planned modernisation of the Planchy maintenance facility, tpf investigated whether fully automated shunting operations using Automatic Train Operation Grade of Automation 4 (ATO GoA4) could be implemented with the existing vehicle fleet within the Planchy – Bulle area. The study assessed technical feasibility, operational implications, and the economic viability of introducing automated shunting.

PROSE supported tpf SA throughout the entire feasibility study in a structured, multi-stage process involving operational, technical, and management stakeholders. We first analysed the current operational processes, infrastructure, and regulatory conditions. Based on this, we jointly developed a target operating concept for automated shunting.

To evaluate possible implementation strategies, PROSE performed a risk analysis and developed several technically consistent solution variants using a morphological analysis method. These options were then compared through a transparent cost-benefit assessment, enabling a structured evaluation of technical feasibility and operational impact.

Customer benefit

tpf SA received a clear and independent decision basis for the further development of the Planchy maintenance site.

Thanks to the efficient approach, initial results were quickly developed in collaboration with tpf experts and presented to management. Technical feasibility, operational implications and economic effects were presented in a comprehensible and transparent manner.

With our expertise in railway operations and ATO realistic implementation scenarios were developed and efficiently aligned with internal stakeholders. PROSE also supported tpf in initial discussions with potential system suppliers, strengthening tpf’s technical and strategic position.

  • Commercial support for operational leases, contract drafting and LCC assessment

Our approach

The project aimed to ensure that a major European railway operator was well and strategically prepared for an upcoming procurement process for new international high-speed rolling stock. The key challenge was to clarify complex commercial, contractual and strategic requirements at an early stage, to structure them and to coordinate them with each other. This particularly concerned the operating lease model, life cycle costs, contract structures and the prequalification of suitable lessors. Without this targeted preparation, significant risks related to cost, quality, and schedule, as well as limited and ineffective market engagement, would have been likely. The project therefore focused on creating a solid commercial and strategic foundation for a complex international procurement procedure.

PROSE approached the task strategically, systematically and methodically, first analysing and clearly defining the commercial, contractual and time-related requirements of the procurement project. Based on our expertise in international procurement projects and rolling stock leasing models, PROSE developed a clear and practical methodology to prepare the customer for the tender process. We established a transparent project structure and consistently managed deliverables, costs, quality, and risks. In parallel, PROSE supported the pre-qualification of potential lessors and established the basis for well-founded commercial decision-making. Our advisory services also covered the development of robust and market-aligned contractual models. We worked closely with the customer as external commercial project managers on a mandate basis, focusing on solutions and open exchange in order to identify risks at an early stage and create a solid basis for decision-making.

Our approach

The project is part of a shunting locomotive platform programme in which SCHÖMA supplied a shunting locomotive to Alstom for a transport authority in Manila, Philippines. The vehicle is a four-axle, diesel-hydraulically driven shunting locomotive for standard gauge with a total vehicle mass of 60 tonnes. PROSE was commissioned to carry out the complete mechanical development of the bogie.

The scope included the design and engineering of the bogie frame, wheelsets, axle boxes, and the integration of all relevant systems and components. A key technical focus was the limited available installation space and, the safe transmission of longitudinal traction and braking forces from the bogie to the carbody, without significantly altering wheelset loads. The project therefore required a robust, space-efficient, and safety-compliant bogie design suitable for effective production and reliable operation.

At PROSE, rail vehicle development follows the V-model in accordance with EN 50126. For this project, the bogie development was focused on the concept design and final design phases, ensuring an efficient and targeted engineering process. Throughout the development, PROSE placed particular emphasis on a production-oriented design approach, using cost-effective and manufacturing-friendly welded structures wherever possible.

In parallel, the design was optimised regarding both production and life-cycle costs, while consistently meeting safety and performance requirements. Compliance with all relevant safety-related EN standards was embedded in the design process. PROSE’s extensive experience in bogie engineering and our deep understanding of standards and manufacturing constraints enabled a balanced and efficient development approach tailored to the customer’s needs.

Customer benefit

Thanks to the timely and successful completion of the project, the customer received rapid and reliable engineering support within a short timeframe. By selecting PROSE, the customer benefited from in-depth expertise in bogie development, significantly reducing internal effort and development time. PROSE delivered a complete, production-ready bogie design, including a full 3D model, proof of strength, track guidance analysis, and detailed component specifications to support procurement.

All relevant systems, including primary and secondary suspension dampers, gearbox, brake system, and longitudinal and transverse stops, were successfully integrated. The critical challenge of transmitting longitudinal forces without increasing wheelset loads was solved through a cranked pull/push rod with a deep linkage connected to a balancer, resulting in low pitching moments and stable wheelset behaviour. Although no specific standards were required by the end customer, PROSE provided comprehensive and standard-compliant proofs of strength and derailment safety, demonstrating conformity with relevant standards such as EN 13749:2024, EN 13979, DVS 1612 and EN 14363:2016.
