Railway Clothing

Understanding RIS-3279-TOM and Network Rail Compliance

RIS-3279-TOM replaced GO-RT 3279 in 2017 as the UK Railway Industry Standard for high visibility clothing worn on or near operational railway lines. It's based on EN ISO 20471:2013 but adds rail-specific requirements that make railway hi vis clothing distinct from construction or highways workwear. The critical difference? Colour. RIS-3279-TOM mandates fluorescent orange with chromaticity coordinates X:0.588, Y:0.371 and luminance factor minimum 0.4 – zero tolerance. This specific orange provides maximum contrast against railway infrastructure including signals (red, yellow, green lights), overhead line equipment, rolling stock, and natural lineside vegetation.

Network Rail's Full Orange Policy requires all personnel working on or near operational railway to wear orange hi vis meeting RIS-3279-TOM standards. Railway workers wearing non-compliant yellow hi vis from other industries risk disciplinary action and may be refused trackside access by protection controllers. Train drivers need instant recognition at dawn, dusk, and in overcast conditions when visibility is most challenged.

Key Selection Criteria for Railway Work Clothes

RIS-3279-TOM garments must meet EN ISO 20471 Class 2 minimum visibility: 0.50m² fluorescent orange material and 0.13m² retro-reflective tape positioned for 360-degree visibility. Many railway safety clothing options in this collection achieve Class 3 (0.80m² fluorescent, 0.20m² reflective) – worth specifying for roles involving prolonged trackside exposure or overhead line equipment work. Retro-reflective tape must meet the highest photometric performance criteria in EN ISO 20471, ensuring visibility when illuminated by locomotive headlights at 400+ metres.

Common specification mistake: assuming any orange workwear qualifies for railway use. Only garments certified to the RIS 3279 TOM standard meet Network Rail requirements. Check product listings for explicit RIS-3279-TOM certification before purchase – supervisors inspect clothing before granting railway access.

Care and Compliance Maintenance

Wash railway orange clothing at 40°C maximum using colour-safe detergent. Fluorescent orange dyes fade faster than yellow – maintaining colour integrity is essential for continued RIS-3279-TOM compliance. Avoid chlorine bleach which accelerates degradation. Replace railway work clothes after 50–75 industrial washes or when: • Orange colour noticeably fades (reducing luminance below 0.4) • Reflective tape shows cracking or peeling • Fabric develops tears or damage

Network Rail mandates pre-access inspection. Faded or damaged garments that no longer meet the RIS 3279 tom standard result in refused entry to operational railway lines.
