Experiences

General:

• Preparation and documentation of electrical concepts for technical offers for new vehicles, refurbishments, component retrofits; presentation of the concepts for different target groups in different bid phases
• Cooperation in projects for the implementation of electrical concepts
  • Analysis and commenting on customer requirements
  • Preparation of requirement specifications
  • Concept adaptation / support in clarification with customers
  • Concepts for functional electrical circuit diagrams
  • Descriptions of concepts and components
  • Support in the commissioning of vehicles
  • Support in the homologation of vehicles (safety verification, clarifications with approval/acceptance authorities, etc.

Special Knowledge:

• Design of conventional electrical safety circuits (up to SIL4), e.g.

• Deadman
• Safety loops
• Vital traction inhibit
• Vital train control (e.g., central door control)
• Monitoring loops

• Diagnostic concepts (incl. preventive diagnostics)
• Integration of train protection systems in trains (hardware)

• Automatic train stop, LZB, ATC (general, different manufacturers)
• Communication Based Train Control (CBTC), suitable up to GoA4

• Driverless and unattended operation up to GoA4:

• Hazard and risk analyses, definition of safety requirements
• Definition of the operational concept
• Remote control in GoA4 operation
• Analysis and description of failure scenarios (use cases)

• Qualitative safety verification for conventional electrical systems

Creation of Concepts Specifically for Metro Vehicles:

In the past, I have often developed concepts for complete systems and for individual components that should be integrated into the overall vehicle system. In my professional life, I have created all types and kinds of electrical circuits of rail vehicles. I have a very good overview of the electrical equipment of the vehicles, especially with metros.

In the past, I have dealt with the following issues, sometimes very intensively:

• Main circuit (design, components, control)
• Auxiliary power supply (AC/DC, design, and control)
• Concept for train control (electronic components, data bus systems)
• Conventional vehicle control including operating mode selection
• Fire alarm systems
• Speed measuring equipment
• “Black boxes”
• Safety loop for emergency brake including components that intervene in it
• Traction interlocking
• Integration of train protection systems
• Passenger emergency intercom systems
• Passenger information systems
• Passenger counting systems
• Radio systems
• Auxiliary equipment
• Interior and exterior lighting
• Heating, ventilation, air conditioning
• Doors (local and central door control, monitoring)
• Compressed air supply
• Integration of mechanical/pneumatic braking systems including control system
• Coupling devices including control
