Shaping the Future of Engineering & Manufacturing

Rail, Transportation & Infrastructure

Rail and transportation infrastructure engineering requires specialized knowledge of the regulatory, safety, and technical standards governing railway systems, rolling stock, signalling and control software, civil infrastructure, and urban transit — where EN 50126 RAMS requirements, EN 50128 safety-critical software, and EN 50129 safety cases define how every system component must be designed, analysed, and verified for authorization by national safety authorities. EMUG delivers rail and transportation infrastructure engineering for rolling stock OEMs, railway system integrators, civil infrastructure contractors, urban transit operators, and transportation infrastructure authorities — covering rolling stock structural design to EN 12663, RAMS analysis to EN 50126, railway signalling and control software to EN 50128 SIL 1 through SIL 4, EN 15085 weld quality engineering for railway vehicles, civil and track engineering, bridge and viaduct structural analysis to EN 1991-2, and railway certification and homologation support for ERA TSI compliance.

Head of Structural Engineering, RAMS Managers, Safety-Critical Software Directors, and Railway Certification Managers at rolling stock OEMs, railway system integrators, and infrastructure organizations engage EMUG when programs require specialist structural analysis for EN 12663 compliance demonstration, RAMS analysis and EN 50129 safety case development for national safety authority authorization, EN 50128 safety-critical software at SIL 3 or SIL 4, EN 15085 welding quality system certification, civil and structural analysis for railway bridges and infrastructure, or TSI compliance assessment for rolling stock entering EU interoperability areas.

All rail and transportation programs at EMUG are structured through the EMUG TRACK Framework — a five-phase delivery methodology covering Technical standards and certification scope definition, Requirements and RAMS analysis planning, Architecture and structural design execution, Compliance verification to EN 50126, EN 50128, and EN 12663, and Knowledge transfer and operational handover. TRACK stands for: Technical scope, Requirements analysis, Architecture execution, Compliance verification, and Knowledge transfer. The framework ensures that railway engineering programs address the complex interdependency between structural, safety, software, and certification requirements.
