Create a stronger foundation for railway signaling engineering
Railway signaling projects depend on requirements that are clear, complete, consistent, and verifiable.
Prover helps railway teams turn fragmented signaling requirements and specifications into a structured, traceable, and verification-ready baseline for digital twins, V&V, automation, acceptance, safety evidence, and lifecycle change.
From fragmented requirements to a trusted baseline

Different interpretations
Requirements are interpreted differently by different stakeholders.
Late gap discovery
Gaps and conflicts are discovered late.
Unclear assumptions
Design and configuration decisions are based on unclear assumptions.
Weak verification readiness
Verification teams struggle to define what must be proven.
Clarification loops
Suppliers and infrastructure managers spend time on clarification loops.
Expensive change
Changes become more expensive because the original intent is not explicit.
Requirement engineering is the first safety-critical control point
In railway signaling, requirements are not just project documentation. They are the foundation for system behavior, verification, assurance, acceptance, and lifecycle control.
Level 0 — Create the truth
Trusted requirement foundation
Structure and validate requirements, assumptions, data, signaling principles, and system logic.
Level 1 — Build and prove
Verification-ready engineering
Use structured requirements in models, digital twins, simulation, verification, automation, and evidence generation.
What you gain from Requirement Engineering
Create a stronger requirement foundation for digital twins, verification, automation, acceptance, and lifecycle change.
Clearer requirements
Turn fragmented specifications and engineering knowledge into a structured baseline.
Earlier ambiguity detection
Identify unclear, conflicting, incomplete, or unverifiable requirements earlier.
Better traceability
Connect source documents, requirements, assumptions, models, verification activities, and evidence.
Stronger downstream engineering
Support digital twins, simulation, formal verification, data preparation, and design automation.
Reduced rework
Avoid late clarification loops, design changes, and acceptance issues.
Lifecycle control
Preserve structured requirement knowledge for upgrades, maintenance, migration, and future projects.
For teams responsible for trusted signaling requirements
Infrastructure managers
Create stronger requirement baselines before tendering, modernization, supplier handover, digital twin creation, acceptance, or lifecycle change.
Suppliers & integrators
Clarify customer requirements, reduce interpretation risk, and create a stronger foundation for design, configuration, V&V, and delivery.
Consultants & engineering firms
Assess requirement quality, identify gaps, support customer decision-making, and define a practical improvement roadmap.
V&V and safety teams
Ensure requirements are precise enough to be tested, simulated, formally verified, and used as evidence inputs.

Structure existing specifications
Turn existing documents, drawings, tables, and rules into a more organized and traceable requirement baseline.
Can we turn our existing specifications into a clearer and more usable requirement baseline?
Identify gaps and inconsistencies
Analyze requirements to find ambiguity, conflicts, missing assumptions, duplicated logic, and unverifiable statements.
Are our requirements complete, consistent, and clear enough for downstream engineering?
Formalize selected requirements
Convert selected safety-critical or behavior-critical requirements into more precise representations.
Which requirements need to be formalized to be verified with confidence?
Build an object and behavior model
Create structured models of signaling objects, rules, scenarios, interfaces, and dependencies.
Can we create a shared digital understanding of what the system is supposed to do?
Prepare requirements for downstream V&V
Structure and trace requirements so they can be linked to models, tests, proofs, evidence, and acceptance criteria.
Can these requirements support simulation, verification, acceptance, and safety evidence?
Applicable across railway signaling requirement foundations
Interlocking systems
Structure requirements around routes, signals, points, locking principles, release conditions, dependencies, and safety rules.
ERTMS and ETCS programs
Clarify and trace requirements across standards, national rules, site-specific data, operational needs, and supplier constraints.
CBTC and metro systems
Structure requirements for capacity, headway, degraded modes, interfaces, automation levels, and operational scenarios.
Digital twins and synthetic environments
Create the structured foundation needed to build and validate useful digital models.
Open signaling and modular architectures
Define interfaces, responsibilities, constraints, assumptions, and expected behavior.
Migration and modernization programs
Extract and structure the requirement baseline needed for controlled modernization.
