RIS-3279-TOM explained: orange hi-vis for GB rail
RIS-3279-TOM is the Rail Industry Standard from RSSB that sets the minimum high-visibility clothing for people working on or near the GB mainline railway.
Updated
Quick answer
RIS-3279-TOM (Issue 2) requires fluorescent orange hi-vis that also meets EN ISO 20471, typically at least Class 2 on the upper body. Network Rail and other duty holders call it up in their own rules. Older garments may still be labelled GO/RT 3279. It is a GB rail standard; Irish Rail and Translink set their own requirements, so check with them.
