Labels and nameplates on railway equipment have a harder life than most. They face vibration, weather, cleaning chemicals and decades of service, and on rolling stock they also have to meet fire safety requirements. This guide explains what rail buyers typically need to specify, so the labels you order are accepted first time.
Rolling stock vs infrastructure
The first question is where the label will be used, because the requirements are quite different.
- Rolling stock (trains, trams and other rail vehicles) — interior and exterior labels, equipment identification, electrical cabinet labels and nameplates on vehicle systems. Materials used on vehicles are subject to fire safety requirements, covered below.
- Infrastructure (track-side, signalling, power and stations) — asset identification, location cabinet labels, equipment plates and signage. Requirements are usually set by the infrastructure manager or the main contractor's specification, and the priority is long-term outdoor durability.
If you are unsure which applies, the project specification or your customer's engineering team will tell you.
Fire safety on rolling stock: EN 45545-2
EN 45545 is the European standard for fire protection on railway vehicles, adopted in the UK as BS EN 45545. Part 2 sets the fire behaviour requirements for materials and components, covering flammability, smoke and toxicity. The current edition is EN 45545-2:2020+A1:2023.
Three ideas matter when ordering labels:
- Hazard level (HL1, HL2 or HL3) — set by how and where the vehicle operates. HL1 is the least demanding and HL3 the most.
- Requirement set (R1 to R26) — each type of material or component, and its location in the vehicle, maps to a requirement set with its own tests and limits. Labels are not a "listed" component, so they are usually assessed as non-listed items. Your customer will tell you which requirement set applies.
- Small components — the standard includes provisions for small items by mass. Whether a label qualifies depends on the exact rule your customer applies, so do not assume.
Some operators also have their own requirements. London Underground, for example, has its own materials fire safety standard. Always ask which standard and which requirement set applies before ordering.
Choosing a material for rail
| Material | Typical rail use | Fire safety considerations | Durability |
|---|---|---|---|
| 316L stainless steel | Exterior plates, underframe, track-side assets | Metal is non-combustible; check any paint infill or adhesive | Excellent, corrosion-resistant |
| Anodised aluminium | Equipment plates, cabinet labels | Metal is non-combustible; check any infill or adhesive | Very good, lighter than steel |
| Traffolyte / acrylic laminate | Interior electrical cabinets, panel legends | Plastics need test evidence for the specific requirement set and hazard level | Good indoors; not ideal for long-term UV |
Metal plates are usually the simplest route on rolling stock because the base material does not burn. Paint infills, adhesives and plastic labels still need checking against your requirement. For outdoor and track-side use, 316L stainless steel offers the best corrosion resistance, while anodised aluminium saves weight where it matters.
For interior electrical labelling, Traffolyte labels are common, but only where test evidence covers the application. Our guide What Is Traffolyte? explains the material and its limits.
Fixing and vandal resistance
Vibration and tampering are the two main reasons rail labels fail in service.
- Mechanical fixings (rivets or tamper-resistant screws) are more secure than adhesive alone on vehicles and public-facing equipment.
- Adhesive fixing suits flat, clean surfaces inside cabinets. Check that the adhesive is covered by your fire evidence.
- Plate thickness and corner radius affect how well a plate resists bending and snagging.
Traceability and serialised plates
Rail projects often need serial numbers, part numbers, barcodes or QR codes linked to an asset register. Laser marking suits variable data such as sequential numbering, while chemical etching suits long runs of identical plates. Our guides on asset tagging with QR codes and barcodes and chemical etching vs laser engraving vs UV printing explain the options.
What to send us for a rail quote
- Rolling stock or infrastructure, and interior or exterior
- The fire standard, requirement set and hazard level, if applicable
- Drawings or a label schedule (spreadsheet preferred)
- Material, thickness and finish, if specified
- Fixing method and hole positions
- Quantities, serial ranges and delivery dates
We can send the material data sheet for each material we use, so you can check it against your requirement before you order.
