GO/RT 3279 replaceD with RIS-3279-TOM
The RSSB replaces Railway Group Standard GO/RT 3279 issue 8 with RIS-3279-TOM, with effect from 4th March, 2017. GO/RT 3279 Issue 8 has been withdrawn as it could not be retained as a National Safety Rule and is therefore reclassified. All existing garments certified to GO/RT3279 Issue 8 remain valid but all new garments will be certified to the new RIS-3279-TOM standard. This has no effect on the garments we manufacture and sell but you may notice changes to labels and certification in due course.
