Railway ISA

In the railway domain our engagement as ISA (Independent Safety Assessor) will be a pre-requisite for the approval by the national railway authority. CertX may inspect or certify your product according to the railway standards  (RAMS – EN 5012x or software on board rolling stock – EN 50657).


CertX is your partner in navigating you through this legal framework and we offer the right but lean assessment and certification services which enable you to introduce safe railway products on-time.

Our assessment services can be applied into a variety of railway systems, e.g. locomotives, metros, EMUs, DMUs, on-track machines, fixed installations and its subsystems, e.g. door -, brake or train control systems, signalling, tunnels, stations and platform screen doors.
