Railway rolling stock
You weld for rail
A welded bracket on a bogie frame is railway work, and the standard treats it that way. EN 15085 ties your certification level to the most demanding weld you make, names the person who owns welding coordination, and expects the traceability to prove it. Worgify builds all three as you fabricate.

What it costs you today
Where the record breaks.
The weld performance class sets the certification level
EN 15085 assigns each weld a performance class from its safety relevance and stress, and your certification level — CL1 to CL4 — is fixed by the highest performance class you actually produce. Take on one CP A joint and the whole shop is judged against CL1, whether the rest of the work needs it or not.
Cost Bidding work your certification level does not cover, or carrying a CL you cannot evidence when the auditor asks
Welding coordination has to be a named person, with a deputy
EN 15085-2 requires responsible welding coordination personnel to ISO 14731 — a named coordinator with the competence for your level and a named deputy who can stand in. When that authority lives in an org chart instead of in the records, a signature on a joint cannot be traced back to a qualified person who was actually authorised on the day.
Cost A coordination gap that reads as a systemic finding, not a one-off
Traceability the notified body can follow from joint to certificate
EN 15085-5 wants inspection, testing and documentation that ties every safety-relevant weld to its performance class, its procedure, the welder, the coordinator and the acceptance result. Reassembled from folders after the fact, that chain always has a link missing exactly where it matters.
Cost Documentation nonconformities on welds that were made correctly but never fully evidenced
Who this is for
You weld railway vehicles or their components — car bodies, bogie frames, underframes, couplers, and the brackets, mounts and sub-assemblies that hang off them. You may be the vehicle builder, or a sub-supplier who welds one part that ends up on a train.
It makes no difference to the standard: a bracket welded to a bogie frame is railway work, and it is in scope. If you weld safety-relevant parts for rail, EN 15085 governs you the same as it governs the prime.
The regime that governs you
EN 15085 — Railway applications: Welding of railway vehicles and components — is the sector standard, layered over the general welding quality requirements of ISO 3834.
Two mechanisms shape how you work:
The weld performance class drives your certification level. EN 15085-3 assigns each weld a performance class — CP A, CP B, CP C1, CP C2, CP C3 or CP D — from its safety category and the stress it carries.
Your manufacturer certification level then follows the most demanding weld you produce:
- CL1 for the highest performance classes,
- down to CL3 for the lightest welding,
- CL4 reserved for organisations that design or coordinate but do not weld.
One CP A joint pulls the whole certification to CL1.
Welding coordination is named, and stricter than the baseline. EN 15085-2 requires responsible welding coordination personnel in line with ISO 14731, with competence matched to your certification level.
It expects a named coordinator and a named deputy, so authority over a safety-relevant weld never sits vacant. This is deliberately more demanding than general fabrication.
Underneath, ISO 3834 supplies the welding quality management requirements. EN 15085 is the rail-specific layer on top of it, never a separate product.
The specific pain of proving it
The recurring trap is that all three of these have to reconcile on every safety-relevant weld:
- the performance class,
- the certification level it implies,
- the coordinator who was authorised on the day.
The notified body follows that chain per EN 15085-5.
When performance class is a note on a drawing, coordination is an org chart, and traceability is a folder, the links only look connected until someone audits them.
Where Worgify fits
Worgify Fabrication is one system for the shop, with the EN 15085 and ISO 3834 layers switched on per job:
- Welding management that holds your WPS, WPQR and welder qualifications as live records and computes the qualified range from the essential variables — so whether this welder and this procedure cover this joint, at this performance class, is answered by the engine rather than from memory. Performance class travels with the joint, and the responsible coordinator and deputy are recorded against the work, not implied by a title.
- The MRB/MDR dossier built as work happens — each safety-relevant weld linked to its performance class, procedure, welder, coordinator sign-off, NDT result and the material certificates (EN 10204) behind it, so the EN 15085-5 documentation a notified body follows is assembled continuously instead of reconstructed before the audit.
Your certification level is only ever as sound as the weakest link you can evidence. Worgify makes that evidence a by-product of doing the work correctly.
