Our Sectors

Railway

Railway and signalling systems are the lifeblood of safe, efficient mass transit and freight networks. Yet they operate in a demanding environment: evolving safety regulations, high expectations for availability, reliability, and maintainability, and the relentless pressure to modernize legacy systems. Hardware, software, and control logic must interoperate seamlessly, satisfy stringent standards, and survive harsh environments. Certification pathways are rigorous, documentation is exhaustive, and any oversight can compromise system acceptance, cause delays, or threaten safety.

Your Experienced Engineering Partner

Engineering for Compliance

At DMD Solutions, we bring the rigor of aerospace-grade safety engineering to the railway domain. We partner with original equipment manufacturers, system integrators, signaling suppliers, and transit agencies to translate high-level safety and availability goals into proven, certifiable engineering designs. From system architecture to hardware, firmware, communications, and safety cases, we embed RAMS discipline from day one.

‍

RAMS & Safety Lifecycle Engineering: Applying EN 50126 (or equivalent) to specify, allocate, and validate reliability, availability, maintainability, and safety requirements throughout system development.
Hardware / Electronics Design & Validation: Design hardware for signaling or control systems conforming to environmental, electromagnetic, vibration, and shock constraints (e.g. EN 50155).
Firmware, Embedded & Software Safety: Develop software under EN 50128 or EN 50716, define safety integrity levels, perform V&V, tool qualification, and integration.
Communication & Interface Assurance: Design and verify safe communication channels in accordance with relevant standards (e.g. EN 50159), ensuring integrity even under failure or interference.
Safety Case & Independent Assessment Support: Prepare safety justification, hazard analyses (FMEA, FTA), safety arguments, and support independent safety assessor reviews.
Regulatory & Certification Consulting: Guide the pathway through assessment bodies, coordinate with Notified / Designated Bodies, and manage compliance in different national markets.

Regulation

Certification or assessment to CENELEC standards typically involves:

RAMS demonstration following the EN 50126 lifecycle model.
Safety Integrity Levels (SIL 0–4) allocation for both hardware and software functions.
Independent Safety Assessment (ISA) by accredited assessment bodies (Notified or Designated).
Safety Case preparation under EN 50129, showing that all hazards are mitigated and the system is safe for operation.
