Rolling Stock & Vehicle Engineering
New, upgraded and refurbished locomotive design for manufacturing; wagon structure design, build and approval; and integration of battery, dual-fuel and hydrogen powertrains into rail applications.
Entra Engineering is a specialist railway and vehicle engineering consultancy — designing rolling stock from first principles, simulating it in the cloud, and advising on the corridors, fleets and decarbonisation strategies that move heavy transport forward.
Multidisciplinary rail engineering — rolling stock and components designed, tested and homologated under one team.
We were founded on a simple idea: that the greatest opportunities in heavy transport lie at the intersection of the transport and energy sectors.
Entra Engineering is a specialist railway and vehicle engineering consultancy operating from South Africa and serving clients internationally. Our work helps rail operators, rolling-stock owners and infrastructure developers modernise their assets, decarbonise their fleets, and plan new corridors with confidence.
We combine deep, hands-on locomotive and wagon design experience with advanced simulation, electrical and electronic engineering, and a pragmatic, commercially-aware approach to consulting — from a single component to a full corridor study, with the same rigour throughout.
Finding the balance and synergies between energy and transport — technically, commercially and operationally — is the thread that runs through everything we do.
From concept and feasibility, through detailed design and simulation, to procurement, testing, commissioning and in-service fleet support.
New, upgraded and refurbished locomotive design for manufacturing; wagon structure design, build and approval; and integration of battery, dual-fuel and hydrogen powertrains into rail applications.
Rail-freight corridor feasibility, demand modelling and traffic forecasting, fleet sizing, service development, and capital and operating cost estimation — engineering reality brought to commercial planning.
Multi-physics simulation on cloud-resourced platforms: structural FEA (EN 12663 loads), CFD, heat transfer, electromagnetics, and multi-gas modelling including hydrogen leakage and plume propagation.
Large vehicle assemblies in CAD with live client interaction, manufacturing drawings and weld maps, driveline and HMI design, plus configuration control, BOM creation and strategic procurement.
Locomotive electrical systems design, integration and testing; schematics, wiring and component selection; large power-electronics testing; and embedded software for vehicle control and monitoring.
Rolling-stock strategy and fleet renewal, technical due diligence and market valuation of locomotives and wagons, facility due diligence, and strategic sourcing and procurement to client requirements.
Static and dynamic testing of locomotives and wagons, regulatory approval and safety-regulator submission support, telematics and monitoring, and fleet and asset lifecycle management.
Specialist capability in decarbonisation — dual-fuel, hydrogen and battery rolling stock — where most consultancies have to subcontract.
Discuss a briefThrough our own licences and partnerships we run engineering and simulation software on cloud infrastructure — for speed, parallel processing and remote collaboration, with clients given live access to results.

From a single bracket to a full corridor study, we cover concept, design, simulation, procurement, testing and fleet support under one roof.
Specialist capability in decarbonisation — dual-fuel, hydrogen and battery rolling stock — where most consultancies have to subcontract.
Web-based CAD and simulation give clients live access to designs and results, with faster turnaround and parallel processing.
We quantify uncertainty, set out clear frameworks, and give clients deliverables they can act on with confidence.
Led by a team with deep, hands-on experience in locomotive and wagon design, simulation, electrical systems and project delivery.
Our core leadership is supported by a full-time team of mechanical, electrical, electronic and software engineers, part-time specialists, and a standing network of retired railway engineers who contribute deep institutional knowledge to our projects.
