The decision to procure a second unit confirms that the original solution met the customer’s expectations and that the updated version continues to support their operational needs.

 

 

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.

Project tasks

  • Project audit
  • External advice
  • Second opinion
  • Mediation

Our Approach

​Verkehrsbetriebe Zürich (VBZ) is procuring a new depot management system (BMS) from PSI Transcom GmbH to control its tram depots and bus garages. PROSE carried out an independent project audit on behalf of both parties. The audit aimed to determine whether the project was being handled by both parties in accordance with the requirements for a project in the public transport sector. In addition, VBZ wanted to clarify the extent to which the supplier’s project organisation ensured qualitative and timely project execution. Furthermore, it should be clarified whether any suboptimal project organisation could result in additional financial expenditure on both sides.

PROSE carried out the audit in a two-stage process. In the first phase, both parties were interviewed on-site in an audit meeting about the key issues identified and their respective views were recorded. In a subsequent joint meeting, the first draft of the audit report, including the recommendations of the PROSE auditors, was used as the basis for an initial review. The second phase was organised by focusing on individual key topics in joint meetings of all three parties. Finally, the findings based on the audit report and the recommendations were discussed and finalised.

Customer benefit

VBZ and PSI benefited from the PROSE auditors’ independent perspective and experience in project management and operational issues. By analysing individual key topics, it was possible to illuminate the respective points of view and highlight the perspectives of both parties. As a result, both parties were able to identify potential for improvement in the collaboration.

 

 

Requirements for battery vehicles

Customer: SBB AG, Switzerland

Project tasks

  • Review of the standard requirements catalogue
  • Classification of the requirements
  • Categorisation and adaptation of requirements
  • Integration of the requirements into the requirements management system
  • Evaluation of the offers
  • Conversion and import of the requirements specification

Our Approach

Swiss Federal Railways SBB is preparing for the tender to procure new vehicles that replace the Tm 234 fleets of the first, second, and third series. These new vehicles must fulfil the operational requirements of both existing fleets and be climate-neutral. As the Federal Office of Transport (FOT) has yet to approve finalised regulations for battery-powered vehicles, SBB is facing challenges regarding the approval of battery operation. Therefore, SBB needs support for the battery subsystem to correctly integrate the specific requirements for the battery system into the specifications.

PROSE supported SBB in reviewing the content of the standard requirements catalogue for the battery subsystem (SAK – System Batterie). The task included not only suggesting content adjustments and additions but also classifying the requirements into functional and non-functional categories. In addition, PROSE categorised and adapted the requirements according to the “MUST” and “SHOULD” criteria and submitted proposals for weighting these criteria for the evaluation matrix.

Based on this preliminary work, the specified requirements were integrated into the requirements management system Re-qSuite®. There, the requirements were evaluated individually, and a corresponding binding force was given to evaluate the bids received in the upcoming tender. The specifications were then converted into a format that SBB could import into its requirements management system, Polari-on®.

Customer benefit

SBB received a clear catalogue of questions and an annotated requirement specification, which made the requirements more precise and easier to understand. Checking, evaluating, and identifying requirements that require a risk assessment contribute to quality assurance and minimise potential risks in the project. The risk assessment and the binding nature of the requirements enable better preparation for the tender, which improves the quality of the bids received. Converting the specifications into a compatible format for SBB’s requirements management system ensures smooth integration and utilisation of the requirements by the customer.

 

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.

  • Identification of the requirements that require a risk assessment
  • Creation of a risk assessment
  • Transfer of the requirements into a requirements management system (ReqSuite®)
  • Individual assessment and binding of the requirements

Our Approach

PROSE has drawn up a questionnaire based on these specifications in the sense of “Does a manufacturer have sufficient information? Are the requirements sufficient for the product to be used by SBB”. PROSE checked and evaluated the requirements from the existing specification. The annotated requirements specification was discussed and agreed upon together in a workshop and the requirements requiring a risk assessment were identified. Subsequently, a risk assessment was prepared. The requirements were transferred from the developed basis into a requirements management system (ReqSuite®). The requirements were evaluated individually and given a binding nature in order to evaluate offers received in the subsequent call for tenders.

The requirements specification was then converted into a format that SBB could import into its requirements management system (Polarion®).

Customer benefit

The client received a specification sheet with comments and a supporting questionnaire that allowed him to formulate the requirements more precisely and comprehensibly. Testing, evaluation and identification of requirements that require risk consideration contribute to quality assurance and minimise potential risks in the project. The risk consideration and the binding nature of the requirements enable better preparation for the tender, which improves the quality of the incoming offers. The conversion of the requirements specification into a compatible format for SBB’s requirements management system ensures a smooth integration and use of the requirements by the customer.
