  • 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.

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.

High-speed rail track symbolising strategic procurement and commercial project management for international rolling stock programmes by PROSE.

Strategic commercial project management for the procurement of high-speed rail vehicles

Project tasks

  • Strategic support in the procurement process
  • Project planning and management (deliverables, deadlines, costs, quality, risks)
  • Preparation and implementation of pre-qualification for lessors
  • 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.

Innovative service and operating concept for S-Bahn transport

Customer: Forchbahn AG, Switzerland

Project tasks

  • Scenario and variant supply and operating concept 2035+
  • Concept for on-demand operation with ATO
  • TARGET system architecture and gap analysis to the ACTUAL system landscape
  • Determination of requirements for later migration of the new vehicle

Our approach

PROSE supported Forchbahn in the tendering process for a new vehicle fleet. This also raised questions about the future service and operating concept of the S18 Zurich Stadelhofen – Esslingen line. In order to utilise the opportunity of a new vehicle fleet, PROSE developed various scenarios regarding vehicle lengths and the change in the current service concept through the use of automatically operated vehicles in the direction of on-demand operation at off-peak times. The scenarios were developed for different service levels, depending on the time horizon.

Based on the existing old vehicles, the timetables, the planned timetable and the frequency surveys of current operations, we analysed possible vehicle concepts and the resulting number of new vehicles. We specifically analysed the possibilities with long and short trains as well as the operational and technical reserves. We also developed a 2035+ service and operating concept using fully automated multiple units on the Forchbahn’s infrastructure. In addition to the migration and service steps in the introductory phase, this also included the concept for the introduction of on-demand operation during off-peak times. The tender process defined a target system architecture and vehicle requirements for future migration.

Customer benefit

Based on the actual data, PROSE conceptualised the target state and derived opportunities and risks for the respective thrusts in the service and operation. These were reflected in workshops with those responsible at Forchbahn. The results were integrated directly into the tender documents. This ensures that the vehicles are suitable for operation in the long term and that nothing stands in the way of the subsequent implementation of ATO-on-demand operation. PROSE’s knowledge helped Forchbahn make well-informed decisions early in the process, reducing future risks and supporting long-term operational efficiency.

 

 

Cybersecurity Awareness

Project tasks

  • PROSE presentation on the current state of the railway industry
  • PROSE presentation on the future development of the railway industry
  • In-depth discussion on TS 50701, security vs. safety and discussion on standards
  • Interactive brainstorming on the gap analysis
  • Consolidation of the results of the gap analysis and prioritisation
  • Analysis of the customer’s security documentation
  • Summary and definition of the next steps and goal

Our approach

The digital transformation of the rail industry is accelerating at an unprecedented pace. With increasing connectivity comes the urgent need to improve cybersecurity frameworks to ensure resilience against evolving threats. A recent industry workshop highlighted key findings on the current state of cybersecurity in railway systems and the expected regulatory changes that will shape the future.

Security in the railway sector has traditionally focused on protecting people and machines. However, cybersecurity has now become a critical factor in protecting IT systems, infrastructure and sensitive data. Despite their relevance, many existing railway standards provide only limited guidance on cybersecurity. Important standards such as EN 50126, EN 50716 and EN 50129 recognise security concerns but do not provide concrete measures. The IEC 62443 series, which emerged in the 2010s, has become a fundamental security framework, but its full integration into railway systems is still a work in progress.

A key challenge in cybersecurity is the human factor. Unclear role definitions in projects can lead to security risks – for example, through software updates that are implemented without sufficient validation and can compromise critical systems. Clear role definitions and structured safety processes are necessary to minimise such risks.

The future of railway safety will be shaped by new guidelines and harmonised standards designed to close existing safety gaps. Several regulatory developments will redefine safety requirements in the sector. The NIS 2 Directive obliges operators of critical infrastructure, including the railway industry, to take comprehensive cybersecurity measures. Companies in the supply chain will also have to prove their compliance in future.

The Cyber Resilience Act (CRA) places strict security requirements on manufacturers and suppliers of digital products, including railway technology. IEC 63452 is expected to become a global benchmark for cybersecurity in railway systems and combines elements from IEC 62443 and TS 50701 to create a standardised security framework. In addition, there is a trend towards common cybersecurity services – for example in the areas of authentication, logging and network security to ensure standardised protective measures for critical rail systems.

Customer benefit

Railway operators, manufacturers and suppliers must proactively adapt to these new regulations. Key recommendations include:

  • Identification and inventory of all assets (especially SW)
  • Conducting cybersecurity risk assessments to identify vulnerabilities
  • Establish clear security requirements for suppliers and ensure compliance throughout the value chain
  • Implementing security-by-design principles in the development of new products
  • Strengthen security incident response capabilities to effectively manage threats

By taking a proactive approach, the industry can ensure the safety, reliability and resilience of railway systems in an increasingly connected world.
